The Perseus Constellation: The Milky Way
Perseus Constellation The Perseus constellation is a constellation that appears in the northern
hemisphere and is named after the Greek mythological hero "Perseus." The constellation can be seen
during fall and early winter (August to March). The constellation can also be seen from mid–spring
to early summer in the southern hemisphere. The three spiral arms of the Milky Way can be seen
behind Perseus (stardate.org). The Perseus constellation was first taken note of by Ptolemy in the
2nd century. Perseus was a Greek hero who was a son of Zeus. After Perseus' birth, he was locked in
a chest with his mother and cast out to sea. This was because an oracle told his grandfather, Acrisius,
that he would die by the hands of his grandson. ... Show more content on Helpwriting.net ...
This galaxy is home to supernova SN 2006gy, which was a supernova that was spotted in 2006. This
supernova was the second brightest object in the observable universe (constellation–guide.com).
There is a cluster of galaxies in the Perseus constellation called the "Perseus Cluster." This cluster is
home to thousands of galaxies and one the most massive objects known in the universe. This cluster
of galaxies is moving away from us at the rate of 5366 kilometers a second. At the moment, it's
about 240.05 million light years away (constellation–guide.com) . Another interesting celestial
object in the constellation is NGC 1275, which is a type 1.5 Seyfert galaxy. This galaxy is located in
the heart of the Perseus Cluster mentioned earlier. This galaxy gives off powerful radio emissions
and x–rays. It is believed that there is a supermassive black hole in the center of this galaxy. NGC
1275 is a dominate galaxy in the Cluster and spans more than 100,000 light years. The galaxy has a
delicate network of filaments that should have been destroyed by collisions with smaller galaxies,
but strangely haven't been. It is believed that these filaments are held together by very strong
magnetic fields

Planetary Nebulae Clouds
Nebula or the plural nebulae is derived from the Latin word for cloud(s), and is a term traditionally
used by astronomers to describe the vast gaseous structures which exist throughout the universe.
Nebulae now have been divided into five major categories due to their reflective and observational
characteristics, these being emission nebulae, reflection nebulae, dark nebulae, supernova remnants
and planetary nebulae.
In fact, the term planetary nebula is a misnomer as they have nothing to do with planets or planetary
systems as the name was derived by eighteenth–century astronomers, William Herschel et al, who
due to the restrictions of observational technology available at that time i.e. small telescopes first
thought they either looked like the gas–giant planets of our solar system or stars forming new
planetary systems.
Planetary nebulae are often given the connotation PN or PNe for the plural by astronomers and
exhibit the final stage of a star's life whose initial size is approximately between 1 and 8 solar
masses, where the unused gases and elements left from nuclear fusion are blown away from the
remaining core producing a luminous colourful halo around it. These phenomena can be very short
lived in astronomical terms, possibly just tens of thousands of years.
To reach this final stage of existence all stars go through the same accepted pattern of evolution,
except in the case for large mass stars who have much shorter lives due to burning their hydrogen
fuel

Extrasolar Planets Essay
Humans have longed to believe in extrasolar planets, as surely there have to be planets elsewhere in
the universe. Claims of supposedly discovered extrasolar planets can be dated back to 1855 when
Captain S. W. Jacobs from the Madras observatory, claimed that he had discovered a planet orbiting
a binary system (Jacobs 1855), all the way up until 1991 when a team of astronomers announced
then retracted the alleged discovery of an extrasolar planet around a pulsar star (Lyne and Bailes
1992). Planets are extremely hard to detect as they are a very faint light source and the light from its
parent star is much brighter and essentially blocks out light from a planet (Winters 1996). It was not
until 1992 when the first exoplanets were confirmed ... Show more content on Helpwriting.net ...
Planets have mass and therefore have an effect on their stars orbit causing it to wobble. The wobble
in the case of a pulsar star is seen as the periodic delay in the arrival of the pulses from the pulsar
star (Wolszczan 1994). Due to the nature of a Pulsar star we can detect perturbations in its orbit
through its pulses but to detect perturbations in other stars orbits, astronomers use a stars radial
velocity.
The radial velocity method was used to detect the first exoplanet, 51 Pegasi b (51 Peg b) around a
main sequence star, 51 Pegasi (51 Peg). The radial velocity method uses the variations in velocity of
a star due to the gravitational pull from an exoplanet (Lissauer 2002). Furthermore the velocity isn't
measured in terms of actual speed but in terms of light based on the Doppler effect. The Doppler
effect occurs when a star moves. When it moves toward us, its wavelengths of light are shortened
and when a star moves away from us, its wavelengths of light are lengthened. Through the
continued observation of the Doppler effect on a stars spectrum of light, the velocity of a star is
inferred. Any change in a stars velocity is caused by a sufficiently massive companion, an exoplanet
(Lissaeur 2002).
The first exoplanet found, Peg 51 b, challenged the then present theory of giant planet formation.
Models of giant planet formation stated that Jupiter–like planets form at distances of 4–5 AU, AU
being the distance from

Why Are Stars Mistaken For Stars
Also known as the ¨Stellar nurseries¨ – i.e. The place where stars are born. And for many centuries,
distant galaxies were often mistaken for these massive clouds. Approximately 99% of the ISM is
composed of gas, while about 75% of its mass takes the form of hydrogen and the remaining 25% as
helium. The interstellar gas consists partly of neutral atoms and molecules, as well as charged
particles (aka plasma), such as iron and electrons. The gas is extremely dilute, with an average
density of about 1 atom per cubic centimeter. In contrast, Earth's atmosphere has the density of
approximately 30 quintillion molecules per cubic centimeter (3.0 x 10¹⁹ per cm³) at sea level.

Black Holes And Its Effects On Society
Supermassive black holes are so mysterious when it comes to the knowledge we know about them.
We still don't know much about them and there will always be conspiracies about them, but we still
need to find more information about them to understand more. Black holes are developed when a
star's core collapses and then mass is getting eaten by the core which leads to the star to die in a
supernova explosion. This can go two ways, one is that the star turns into a neutron star, and the
second is it turns into a black hole but only if the star is massive enough. There are known to be
three kinds of black holes. Intermediate, stellar, and supermassive black holes. We still don't know
how supermassive black holes are formed, but most scientists ... Show more content on

It is called Cygnus X–1. Rockets that were carrying a device called Geiger counter that measure
radioactivity by counting ionizing particles. Eight X–ray sources were found and scientist detected
radio emissions from Cygnus X–1. A massive hidden companion was found and that was considered
the first black hole to be discovered. (6) We have a lot of evidence to prove that supermassive black
holes exist in galaxies. Scientist found evidence of a supermassive black hole in the center of the
Milky Way, the galaxy NGC 4258, galaxy M87, and several more. Scientist verified the existence of
black holes by studying the speed of the clouds of gas orbiting the galaxy regions. In 1994, the
Hubble space telescope measured an unseen object that had an estimated mass of about 3 billion
times the mass of the sun in our solar system. The unseen object was located in the center of the
galaxy M87. Scientist measured the mass of the object through the motion of the object whirling
around the center. (2) More evidence for the existence of supermassive black holes is the existence
of quasars. Quasars are a massive and extremely remote celestial object that emits large amounts of
energy. They are also one of the brightest objects in the universe. They are typically more than 100
times brighter than the galaxies they're in. Quasars emit light through disks of gas and stars that are
known as an accretion disk. The accretion disk surrounds black holes. The closest quasars are

Cepheus is an inconspicuous constellation, which is dimmer than most and in the northern
hemisphere located west of Cassiopeia. It has been recognized that the binary star Cephei from its
constellation, will be the next Polar star between AD 3000 and 5200 (fourth and sixth century), and
will be in a position adjacent the celestial pole around AD 4000 (fifth century). The constellation
encompasses various nebulae, star clusters and galaxies such as the Milky Way which transverses an
area of the Cephus constellation by way of its adjoining southern space with Lacerta. The
constellation Draco is another circumpolar constellation, which is observable in the Northern
Hemisphere from the September equinox to the December solstice. It is a very luminous
constellation that consists of four stars resembling a trapezoid. Draco's constellation consists of
various interacting galaxies whose gravitational fields causes disturbances to one another and along

Throughout the history of humanity, numerous scientists have been intrigued by the search for
inhabitable exoplanets. To date, such ventures are still in the developmental stages and the discovery
of life beyond earth and the solar system , regardless of how primitive it may be, may soon be
regarded as a fundamental breakthrough in astronomy (Jones & Mukai, 2007). The fundamental

2011). The closest known exoplanet orbiting star is called Epislon Eridani, which is 63 trillion miles
away – it is close to 14,000 times away from Neptune, the farthest planets in our solar system
(Horner & Jones, 2010). Due to the great distance, exoplanets cannot be viewed directly since the
amount of light they reflect is too faint to be detected from a far off distance (Horner & Jones,
2010). Alternatively, scientists infer the presence of an exoplanet from the changes in wavelength of
light illuminating from the star, this may be caused by the gravitational pull from an orbiting planet
or the regulation of brightness of the star due to transiting planets. When Fermi Paradox was
proposed initially, most people thought planets were rare. Nevertheless, since then the astrological
tools have discovered the existence of numerous exoplanets. However, with each new discovery of
an earth–like planet for instance Epislon Eridani, it becomes less likely that there could exist a
planet apart from the Earth that can support life. Using methods such as those stated above,
scientists have been able to discover hundreds of exoplanets and the first detection was in 1995.
Once they detect one, they begin evaluating it to ascertain whether it can support life. Further, they
analyze the light spectrum that radiates from the star in order to reveal the properties of the planet.
The hunt is still on for planets, which are about the size of earth and those that are

Exoplanets
An exoplanet can be defined as a planet that orbits a star outside the solar system. One of the many
exoplanets that could possibly be habitable in the near future are far away. For example, Kepler–186

First off, the most common way to find new planets is Radial Velocity. The Radial Velocity method
relies on the fact that a star does not remain completely stationary when it is orbited by a planet. It
moves, ever so slightly, in a small circle or ellipse, responding to the gravitational tug of its smaller
companion. When viewed from a distance, these slight movements affect the star's normal light
spectrum, or color signature. If the star is moving towards the observer, then its spectrum would
appear slightly shifted towards the blue; if it is moving away, it will be shifted towards the red.
Secondly, Transit Photometry is the second most common method. This method detects distant
planets by measuring the minute dimming of a star as an orbiting planet passes between it and the
Earth. The passage of a planet between a star and the Earth is called a "transit." If such a dimming is
detected at regular intervals and lasts a fixed length of time, then it is very probable that a planet is
orbiting the star and passing in front of it once every orbital period. Lastly, the method of
Microlensing is Microlensing is the only known method capable of discovering planets at truly great
distances from the Earth. Whereas radial velocity searches look for planets in our immediate galactic
neighborhood, up to 100 light years from Earth, and transit photometry can potentially detect planets
at a distance of hundreds of light–years, microlensing can find planets orbiting stars near the center
of the galaxy, thousands of light–years away ( How to Search for Exoplanet.). These methods are
detrimental to the discovery of new planets from far

Limitations:
In a tree network, a failure to one cable will isolate the workstation that links to the switch of the

when trying to communicate with the workstation that is down from the tree network.
If the central system goes down, the entire network that relies on it will suffer in performance or

The Discovery Of Interstellar Travel
The idea of interstellar travel was explored methodically in order to answer why one would want to
travel to other stars, where in space could humanity realistically travel to, what factors are
preventing mankind from reaching these stars and how can they could be overcome. The
inquisitiveness of the human mind and the fact that Earth will not be habitable forever is a
substantial motivation in favour of interstellar travel. The main requirement for a habitable planet is
that it is in the "Habitable Zone" where it is not too close nor too far from the star it is orbiting, but
is situated where the water on the surface of the planet is in liquid form. There are many issues that
limit one 's ability to travel to the stars. The most significant issue being the vast distances between
the stars and the time it would take for the journey to be complete, which would permanently
damage the human body. The most promising rocket that could handle the voyage would be a
nuclear rocket, however there are still many developments that need to be made in that field to
render it a strong possibility. One of the biggest reasons as to why humanity wishes to explore
interstellar travel is to fuel its curiosity. Civilization would not be where it is today if it wasn 't for
the previous species ' desire to discover more about the universe in which they lived.
Many speculate that the idea of voyaging across the universe to other stars is straightforward as it
portrayed this way in

If you know the planets orbital speed and orbital period, we can work out the orbital radius. The
mass of the planet can also determine by the wobble method. As the planet orbit the sun,
gravitational pull of the planet makes the star wobble, changing the sun velocity. This change of
velocity can be detected by astronomical spectroscopy using redshift and blueshift. When the star
wobble closer to us, the star emits higher frequencies, longer wavelength, and showing bluer colour
when detecting to a spectroscope. When the star wobble away to us, the star emits lower
frequencies, shorter wavelength, and showing reddish colour in the spectroscope. How the planet
change the velocity of the sun determine the planet mass as gravitational pull of the planet depends
on the mass of the planet. This transit can also give the astronomer the estimated linear diameter of
the planet. When you know the star size, you can work out the size ratio of the planet and the star
when the planet transit the star. As I mentioned before, knowing the linear diameter of the planet
gives the astronomers the volume of the planet and volume of the planet and its mass determine the
density of the planets.
Knowing the properties of the planets, the astronomers can tell the conditions of the planets like
their atmosphere, and surface environments especially to the exoplanets because this is the only

The original Hotel was a four–storey, rectangular, grey structure built in 1960 in a dull
Russian style. By 1993, the provincial government had funded a new extension and the Hotel now
consisted of two parts: the old four–storey section joined by a modern sixteen–storey extension
perched on a hill behind the old Russian. There was a contrast in the standard of accommodation.
Room rates were cheaper in the old section and so it attracted Chinese visitors searching for quality
economy accommodation. Visiting government officials and higher–end customers on the other
hand felt more comfortable in the newer and naturally more expensive section. There were two
guarded entrances to the Hotel, one on each level. A series of stairways, elevators and a warren of
banquet rooms, hallways, storage areas, offices, cafeterias, and a laundry untidily connected the two
buildings.

Analysis : The Night Sky Planisphere
Summary: For the first part of the lab we measured the right ascension and declination of certain
stars and constellations; we used the star chart like a graph with measurements of time and angles.
Another part of the lab we used a star and planet locator also known as a planisphere to determine
the time and date certain stars and constellations are visible, set, or rise at. Using the planisphere
was quite easy to determine stars and how they correlate to time because it 's pleasant to visualize
and address smaller stars that are not so apparent in the sky to the naked eye.
Questions:
What do your planispheres represent?
Our planispheres are diagrams that depict the date and time a constellation or star will be visible by
it passing through the meridian while facing North to Polaris. The night sky planisphere also depicts
what stars can be seen during any time of the year in specific direction in the sky.
Is it possible to predict a celestial event using planispheres?
Planispheres can only locate stars according to time and position but cannot predict celestial events
like eclipses or asteroids.
What is right ascension?
Right ascension is a measurement of hours and minutes in eastward motion on the celestial equator.
What is declination?
Declination is the opposite of ascension, meaning it 's a horizontal measurement. It is the
measurement of how far the sun is from the celestial equator in degrees from 0 to 90.

to any device within the network has to pass through every device, if one device fails the entire
network goes down. (Ethernetpedia) A Star topology is the second type of topology represented.
This topology is easy to install as well as being easy to expand by connecting additional nodes or
devices. Faults are easily detected and parts are easy to remove. In a Start topology, when devices
need to be added or removed, it does not cause disruptions to the network. This type of topology is
used for many different applications, ranging from small to large networks. (FCIT, Univ. of Florida)

The mesh topology provides multiple routes between devices. Not only does this provide alternates
for file transmission should there be a failure anywhere along the network, but it makes it easy for
additional devices to be connected and will not slow down network traffic. Since networks built
using mesh topology can be large one of the main disadvantages is the difficulty involved with
installation, configuration as well as the on–going maintenance involved. The expense of cabling is
also a disadvantage of mesh topologies as they can take more cabling and more devices than other
topologies. (Networking

The Planet Jay Comes From The Earth
The planet Jay comes from is known as Mir to its inhabitants.
In this universe, there are several sapient species, who originate both in outer space and on Mir. The
human–equivalent, mortal species are lovek, who live down on Mir and, at the time of Jay 's entry
into Ryslig, are just starting to venture into outer space. However, besides lovek there are several
species that should be discussed in some detail for a proper understanding of the setting.
Most immortal species in the setting fall under the umbrella of Spirits, based on the fact they are
composed of Spirit (substances relating to magic and the soul) rather than Flesh (you know, meat).
The universe is dualist and most living things within it fall under one of the two broad categories of
Spirit and Flesh.
First, there are the stareczi, who live in deep space and generally stay away from Mir. They 're
something akin to sapient fungus (or possibly slimes). They have two instars (life stages), which
dictate their place in society.
The first instar is a haploid, unfused individual that grows from a spore. Unfused stareczi live in
loose groups of about five to ten individuals, though pods as large as twenty–five are not
uncommon. The second instar is trickier.
The second instar of stareczi is something between a proper life–stage and pair–bonding. At
maturity, two haploid stareczi fuse into a single, diploid individual who is capable of sporing. Fused
stareczi are solitary and live away from others of their

Short Story
Mh'ale wasn't like the other stars. He was dark, cold, with no light of own to brighten his way
through life. The others, so beautiful and radiant and brimming with energy, had no love for the
freakish thing that inhabited the Nothing with them. Mh'ale envied and despised them in equal
measure, and would weep and wail miserably when they taunted him, the tears puddling and pooling
all around. The stars paid no heed to his misery; they were too perfect to cry, and didn't understand
why the ugly little star was drowning himself. He only ever felt happy when he was bathed in light,
but no matter how hard he begged, the stars refused to share the gifts that came to them so naturally.
They teased and taunted him, allowing slight flickers ... Show more content on Helpwriting.net ...
They didn't deserve the power they so carelessly wore like incandescent cloaks. Only he understood
the importance of the light.
In a fit of rage, he ripped a large chunk of his body away and in one swift motion, threw it at the
nearest cluster of stars. It bodily slammed into Man, one of the largest, taking him by surprise and
expelling an enormous burst of life as it ricocheted off. The piece absorbed the damage it had done
as it collided with one star after the after, each shouting in pain and shock as their light was ripped
away and rolled into the ever–growing ball. By the time Mh'ale had retrieved it, the chunk of rock
had gathered almost of the light the stars had. They were pitiful now, tiny whining things that
angrily flickered at him. He smiled at his prize and took delight at downfall of his tormentors.
Finally, he had their gift. He could become a true star, the largest one of all. He braced himself and
tried to absorb the enormous mass.
It was unlike any feeling he had ever experienced. Something like pain and euphoria shot through
his body as he tried to merge with his creation, the energy permeating his being. It wildly scrabbled
along his surface, the sensation forcing gooseflesh to rise. Once he had swallowed it whole, his
whole body was singing with light, and he was satisfied.
But the light still wouldn't stay. He was a broken star, an ugly star, and holding life wasn't something
he could do. The light tried

The Features Of Distant Planets : How Do We Know?
ESS AS 3.6: The features of distant planets – how do we know?
1 INTRODUCTION
Exoplanets, also referred to as extra solar planets, are planets which orbit around stars in planetary
systems other than our own Solar System. The first exoplanet that was ever discovered was of PSR
B1257+12 A in 1992, since then we have discovered approximately 1932 extra solar planets, 1222
planetary systems and 484 multiple planet systems. A wide range of techniques are used by
astronomers to find exoplanets, most of which uses observation from Earth to deduce exoplanet
locations and properties, features and conditions. There are also many reasons why the astronomers
research into exoplanets, with one of the main reasons being the desire for humanity to leave Earth,
as we would not be able to live in this world forever, whether it is due to induced causes like global
warming or natural causes like the sun aging and eventually exploding as a supernova. Humanity's
time on Earth is finite, which is the main drive for scientists and astronomers alike to discover life as
we know it on extra solar planets in other planetary systems. (Gammon 2013, Exoplanet.eu 2015,
Phoenixpics 2009)
2 SPECTROSCOPY
A fundamental technique that is used for the exploration of exoplanets and their features, properties
and components, is through spectroscopy. Through this technique, astronomers are able to discover
new exoplanets, while also determining its composition, temperature, density, luminosity and
rotation.

The Universe and It’s Phenomena
The Universe and It's Phenomena The universe is an unknown place. Most of it has not been
explored. Some things are known, however. Scientists know a lot about things like the Big Bang and
our Asteroid Belt. Some of the universe's natural phenomenons are yet to be discovered. This article
will explain some of them and why they happen. In the year 1929, Edwin Hubble made a
revolutionary discovery. He learned that the universe is expanding. He saw that the galaxies were
each moving away from us. Edwin knew that for one instance of time, almost 14 billion years ago,
all of the mass of the universe was contained in a single spot. There had to have been a huge
explosion that pushed all the matter away. This explosion is known as the Big Bang Theory.
(www.science.nasa.gov) NASA is now monitoring the expansion of the universe in spacecraft such
as the Hubble Space Telescope and Spitzer Space Telescope. A goal of these telescopes is to decide
if the universe will expand forever, or if it will go backwards and return to the original spot of the
universe. (www.science.nasa.gov) What did the universe look like when it was born? To certain
theories, if we went back and watched the Big Bang, we would see "... a sea of neutrons, protons,
electrons, anti–electrons (positrons), photons, and neutrons" (www.science.nasa.gov.) With time, the
universe would cool and neutrons would either decay or combine with other things. The universe
would look opaque. This is because

Instances like this one where a pop star dies from something they have brought themselves into
overshadows any other important news. A prime example is how Whitney Houston's daughter
Bobby Kristina Brown who passed away through the same means and received the same attention as
Whitney. It is easy to understand why society praises pop stars because they want to live the lavish
life of money, riches and no worries. This can also go back to the sense of individuality pop stars
have compared to military members. It is very easy for someone in Whitney's position to be very
unique and recognizable compared to Lt. Murphy. These reasons are why the majority of people
give more recognitions to Whitney but, it does not make the situation acceptable. Although social
influences and un moral urges should not fully dictate our thoughts it seems that they have. The

or five star Hotel status. Hotel International started taking changing few established policies of
Roaring Dragon Hotel, though the intention was to succeed, but those policies resulted in loss and
also did not help to improve the quality standards, main cause being conflict between the employees
of RDH and HI management.
After RDH was taken over by HI, and since it was a Chinese hotel the its relationship with the
families was given more importance and they were treated friendly with respect, (Grainger, 2008)
but after the contract everything changed, they were not treated friendly which led to depression
among the employees. RDH staff was facing lots of issues like working for long hours under HI and
they were feeling the pressure and fear of being laid off in case they don't work and much of the
staff which was working for past 30 years had to speak in English, all these factors also lead few of
them to start looking at opportunities outside RDH.
The turnover rate at RDH should have be reduced, HI should have taken care of the staff with little
more respect. They should also have appointment managers who at least had done their education in
the west but whose roots are

The Lifecycle of a Star Essay
'There are more stars than all of the grains of sand on earth.'(Star Facts, 2005:1)
Looking up at the sky on a vibrant night, the vision is naturally lit one with millions of vivacious,
glistening stars. The tenacity of this essay is to explore the lifecycle of a star, thence, signify its
manifestation in the universe. A fundamental part of our universe is stars. Hence, these miniature
luminous forms are essentially very immense in magnitude and it is merely due to their substantial
distance from Earth that they appear so trivial. Scientifically, a star is a ball of hydrogen and helium
with sufficient mass that it can endure nuclear mixture at its core. A huge, shining ball of plasma,
whose lustre is an outcome of thermonuclear fusion are ... Show more content on Helpwriting.net ...
The transportation of energy from the core of the protostar to the visible surface layer of the star
begins in a circular motion (as a gas). As a result, this stage connects the gas temperature inside the
protostar to the gas density–this enables it to have a polytropic structure. As a protostar emits, it
shrinks in scope to produce the energy that replaces the discharged energy. This shrinkage increases
both the self–gravity and pressure at the protostar's core correspondingly. This balance produces a
connection between the temperature of the protostar and the gravitational resistance of the star.
Eventually, as the radius of the star shrinks, the temperature will surge to the factor that it reduces,
thus, its density will further increase. However, the visible layer of the star doesn't become affected
in terms of increase in temperature because its location is set by the skill of light to spontaneously
escape from it. Thence, the protostar begins to become more opaque, less luminous, and as an
outcome the radiation of light decreases. It takes a long time for the star to reach its main sequence
because the decreasing luminosity and the increasing thermal energy cause the rate of shrinkage to
slow dramatically. Therefore, the protostar begins its brief life as a charismatic star that diminishes
in lustre on a timescale of hundreds of years. As years goes by, the

Glance upward on a clear, unlit night and one of the most majestic sights available to us on this
Earth reveals itself. Splattered across the asphalt sky, millions –– nay, billions of white droplets hang
as if suspended by the night. Throughout human history, these seemingly infinitely small points of
light enthralled children and adults alike due to their usefulness in navigation, their connect–the–
dot–ability, and their mystery. Who put them there? Why are they there? Questions like these
plagued philosophers for hundreds of years. Finally, around 1590, Giordano Bruno came to a
conclusion that shook the world of Astronomy. He suggested that the sun join the same category of

Also like cars, a much larger star burns more fuel than a smaller star. This difference in "fuel
efficiency" forms the basis for how stars receive categorization. In the eco–friendly section of the
star dealership, one may find the most humble of all celestial objects: The red dwarf. As the name
implies, they usually only possess half the size of our sun or less. The red dwarf's small size and
lack of resources in its creation places it firmly as the most common star in the universe; though,
their lack of size hides from the naked eye. Despite this shortcoming, red dwarfs possess one
advantage over their larger and brighter counterparts: Life expectancy. Of course, these monstrous
spheres of ignited hydrogen possess no life, but scientists consider them "alive" until they run out of
fuel and burn out, and red dwarfs take a long time to burn out. In fact, in the Universe's 13 billion
year long existence, every red dwarf to ever form remains burning to this day. This longevity,
combined with their abundance, makes a planet in a red dwarf star system the perfect candidate for
the first interstellar colony; so despite their relatively quiet existence, these little guys potentially
hold the future of humanity. Want more power than one of those red dwarfs could ever provide?
Look no further than the Blue Giant. These monsters range from twenty–five to one hundred times
the size of our sun. Unlike the relatively cool (3,500 degrees celsius) red dwarfs, blue giants burn

Are Black Holes The Same?
Are all black holes the same?
Introductionhttp://upload.wikimedia.org/wikipedia/commons/8/89/PIA16695–BlackHole–Corona–
20130227.jpg
Once confined to science fiction and a mere mathematical prediction in general relativity by
Einstein in 1916 (although he didn't believe they were possible) and still believed theoretical only 30
years ago, black holes are now believed to be in among the millions within the Universe.
Furthermore latest research predicts there is one in the centre of most galaxies and they are seen as
the ultimate governing body in the formation and destruction of the galaxy. But are these black holes
fundamentally different to others within the galaxy? [1]
Formation

For smaller stars when the nuclear fuel is exhausted and there are no more nuclear reactions
opposing gravity the repulsive forces among the electrons within the star eventually generate
enough pressure to prevent further gravitational collapse. The star then starts to cool and "die
peacefully" comparatively, this type of star is called a white dwarf. When a very massive star about
fifteen times the mass of the Sun collapses after it has exhausted its nuclear fuel it explodes as a
supernova (currently the largest explosions that are known to take place in space) eventually
forming a black hole. [1.1][2]
The second type is supermassive black holes which tend to be around 100 million times the mass of
the Sun, these are believed to be found at the centre of most galaxies, with our own galaxy the
Milky Way having a supermassive black hole Sagittarius A* with a mass of 4 million times the mass
of the Sun at its centre. There are many theories as to how supermassive black holes are formed and
astrophysicists are yet to agree on a consensus theory.[2][4]
One popular theory that involves a large gas cloud which before the first stars were formed which
collapsed into a quasi–star. With an initial mass of that of around 20 solar masses meaning the
supermassive black hole starts off as an intermediate black hole and whether it will develop into a

4. Advantages of the Star Network Design
It is the most cost effective strategy for "cash–strapped" businesses with no special emphasis on
security. Sometimes the cheapest design doesn't always translate into the easiest design. In this case,
the translation is a success. The hub will serve as the intermediary between the computers and the
internet (via cable modem). Also, in this case, easy design also translate into easy troubleshooting of
any network problem. The star network allows troubleshooters to isolate issues on the network
instead of taking the entire local network offline. Moreover, the star network implies direct data
flow from the computers (via hub) to the internet instead of the data flowing through the nodes first.
Hence, speed is a benefit of such a network. In addition, because of the direct data flow
methodology (nodes–to–hub–to–modem–to–internet–and–vice–versa), the data is safe. Finally, the
star network allows for expansion of nodes, hubs, and gateways without losing any of the networks
advantages listed on this page. The owner plans to eventually add 7 more computers to the network.
My recommendation is to purchase an additional hub to manage the 7 additional computers. Also,

an additional modem is needed for load balancing purposes.

Features Of A Network Topology Essay
2.1 Topology:
Actually here we are discussing about a network topology. A topology is the physical configuration
of a network that determines how the network 's computers are connected. The way in which
constituent parts are arranged. The physical topology of a network is the actual geometric layout of
workstations. There are several common physical topologies based on the configuration. They are
Star Topology, Ring Topology, Buss Topology, Mesh Topology, Hybrid Topology and Tree
Topology.
2.2 Star Topology:
Star topology is one of the most common network setups. In this arrangement, every node connects
to a central hub, switch or computer; the hub acting as a server and the peripheral devices as clients.
A major disadvantage of this network topology is that if the central hub fails, all of the connected
devices are disconnected. In a star network layout, each workstation is connected by its own cable
directly to the server. Star networks are usually the layout of choice in schools and offices because
they tend to be the most reliable of the topologies. The visual example shows how this setup gets its
name as it is shaped very much like a star.
FIGURE 2.1: Star Topology
Advantages:
Star networks are very reliable. If one connection fails, it does not affect other users
Very few data collisions as each workstation has its own cable to the server
Good security – no workstation can interact with another without going through the server first

Introduction
Hotels were made popular around Perth region. Most were designed for the purpose of travelers or
tourists accommodations, while others were for business concerns; though some preferred both.
Regardless of the type of purpose, their establishment is for the sake of everyone who needs to be
entertained. However, the preference of guests to choose a suitable hotel depends on its industry
profile. They usually consider factors like price, services provided and accessibility to name the few.
This essay will introduce and propose Pan Pacific Perth hotel by discussing its industry profile.
Essentially, the discussion starts with how it was established, what are its features and probably
would end to convince anyone why to choose Pan Pacific Perth hotel.
Services Provided and their Clientele
Pan Pacific Perth specified seven executive boardrooms, with Meeting Concierge services, in
'Meetings on 5' where clients can discuss business matters. The rooms are packaged with "natural
light, high–speed Internet access, presentation equipment and various other facilities" with hotel
associates that would assist the clients' planning (Pan Pacific Perth, 2016). 'Meetings on 5' can
accommodate 8 to 36 guests for boardroom meetings or 40 to 100 guests theatre style (Aime, 2016).
For bigger events, the hotel provided 600–metre Golden Ballroom with high ceilings and the pillar–

Local Area Network ( Wan )
LAN stands for local area network and is normally a group of computers that share a common
communications line typically, connected devices share the resources of a single processor or server
within a small area such as an office. A LAN may serve as few as two or three users such as in a
home network or as many as thousands of users such as a FDDI network.

A Wide Area Network (WAN) is a communication network made up of computers that are far away
from each other. The most common example of a Wan is the Internet although a WAN doesn't need
to be global to qualify as a wide area network.

The tree allows you to have many servers on the network and you can branch out the network in
many ways. This is useful for colleges, universities and schools so that each of the branches can
identify the relevant systems in their own network.
Advantages
A Tree Topology is supported by many network vendors and even hardware vendors.
A point to point connection is possible with Tree Networks.
All the computers have access to the larger and their immediate networks.
Best topology for branched out networks.
Disadvantages
The Tree Topology network is reliant on the trunk which is the main backbone of the network. If
that has to fail then the entire network would fail.
In a Network Topology the length of the network depends on the type of cable that is being used.
Star Star Topology is the most common type of network topology that is used in homes and offices.
In the Star Topology there is a central connection point called the hub which is a computer hub or
sometimes just a switch.
Advantages
A Star Network Topology is very easy to manage because of its simplicity in functionality.
The problems can be easily located logically in a Star Topology and therefore is easy to troubleshoot

also.
The Star Topology is very simple in format so it is very easy to expand on the Star Topology.
Disadvantages
The Star Topology has to fully rely on the hub and the whole working of the network depends on the
hub.

Personal And Professional Characteristics Of Star Performers
About the Author Robert Kelley, the author of this book is a professor at Carnegie Mellon
University in Pittsburgh, Pennsylvania. He spent years researching the personal and professional
characteristics of star performers. His ideas and work have appeared on NBC Today Show, CBS
Evening News, ABC, CNN, National Public Radio, The New York Times, Fortune, Forbes, Business
Week, The Wall Street Journal, Industry Week, Nation's Business, Barron's, Atlantic Monthly, and in
many other major U.S newspaper. This book, How to be a Star at Work was on the best–sellers list
on Amazon for 20 weeks.
Introduction
How to be A Star at Work focuses on how to improve work ethics and become a star performer. Star
performers are workers who add more value than average workers. They tend to produce better
results and earn quicker promotions than the average worker. They attract a great amount of interest
and admiration within the company. People who admire star producers, assume the results are from
an high IQ or ingrown ability to reason that is better than most people in their situation. It is also
from exceptional personality factors such as self– confidence, and a highly refined social factor such
as being able to gather a team of motivated workers. An academic study of star performers found
high producers were similar to their co–workers in terms of IQ, personality, and social skills.
According to the book, being a star performer has little to do with having a high IQ. It has to do

Network Topologies Network topologies are an important part of the network. Without the proper
topology, the network may not meet the needs of the organization. The layout of a network is
referred to as the topology. How nodes in a network are connected to each other and communicate is
determined by the topology. There are three basic topologies with several typical variations, or
combinations. A description of four topologies follows. Mesh Topology Mesh topology is the first
topology discussed. In a mesh topology, the devices are connected with many redundant
interconnections between nodes. Each device in the mesh topology is connected to every other

Data is transferred quickly without congestion. All computers have the same amount of access to the
rest of the network. Disadvantages to the ring topology are, failure of the network if one computer
fails, isolating problems with the network is difficult, and the addition or subtraction of computers to
or from the network causes disruption in the network. Star Topology The star topology consists of
one central switch, hub, or router to transmit messages. The computer will send a signal to the hub,
which receives and then retransmits the message to all the other computers or devices attached to the
hub. Good performance is an advantage to using the star topology. Centralization of resources, ease
of set up and expansion, and the network still performs properly when one computer fails are all
advantages to the star topology. The expense of installation, extra hardware required, and if the
central hub fails the entire system fails, are disadvantages to the star topology. Ethernet Ethernet is a
network technology for local area networks (LAN). "Ethernet uses a bus or star topology and
supports data transfer rates of 10Mbps."(Webopedia, 2007). Ethernet is the most popular
architecture used today. One advantage to Ethernet is the ease of installation. Ethernet costs less
than other network architectures and is easy to use. Ethernet supports many different kinds of
networking media, which makes it more popular

Entry 11: The American star system and paparazzi was the focus of this lecture and topic of this
entry in the journal. The development of cameras led to the progression of the idea of paparazzi. In
1959 the United States was introduced to the portable zoom lens, this was a drastic advancement in
technology and opened the door for curious fans to discover more of the personal lives of
celebrities. In a sense, they outsmarted the persona that was portrayed publically and strived to learn
