The document discusses the universe, galaxies, and the solar system. It begins by explaining that the universe contains everything that exists, but its size and boundaries are unknown. Galaxies are gravitationally bound systems of stars, gas and dust, such as the Milky Way galaxy. The solar system is located in the Milky Way and contains the Sun and objects that orbit it directly or indirectly, including planets, dwarf planets, asteroids and comets. Black holes are regions of spacetime where gravity is so strong that nothing can escape. The document then provides brief descriptions of asteroids, comets, meteorites and other astronomical objects that make up the observable universe.

Galaxy presentation
There are four main types of galaxies: elliptical, spiral, barred spiral, and irregular. The Milky Way is a giant barred spiral galaxy containing 200 billion stars. Galaxies range in size from thousands to trillions of stars. The Milky Way is approximately 10,000 light years in diameter and contains a supermassive black hole at its center.
Our universe
The document discusses key facts about our planet Earth. It begins by providing context about our solar system and universe. It then explains that Earth is the third planet from the sun and the only planet that supports life. The document goes on to describe how Earth formed from a hot cloud of gases and cooled over millions of years, developing a crust, mantle and core similar to an egg. Volcanoes are mentioned as openings where molten material from the core is forced out of the crust.
Solar System
The Solar System consists of the Sun and objects that orbit it, including 8 planets, dwarf planets, asteroids, and comets. The inner Solar System contains terrestrial planets like Earth that are composed of rock and metals. The outer Solar System contains gas giants like Jupiter and Saturn that account for most of the mass. Objects follow elliptical orbits around the Sun, with closer objects moving faster according to Kepler's laws of planetary motion. The Solar System is believed to have formed 4.6 billion years ago from the gravitational collapse of a giant molecular cloud.

This document provides an overview of human understanding of the universe over the past 3000 years. It begins with ancient Greek philosophers' early concepts of astronomy and the structure of the universe. It then discusses the major scientific breakthroughs from the 15th century onward that led to modern cosmological theories, including the work of Copernicus, Kepler, Galileo, Newton, Maxwell, Einstein and others. The document concludes by noting some of the key discoveries of the early 20th century that helped establish modern physics and our current understanding of the universe.
Stars
A star is a ball of plasma held together by gravity that undergoes nuclear fusion at its core, releasing electromagnetic radiation. Stars exist along a spectrum from hot, blue stars to cooler, red stars and can be classified based on their temperature, luminosity, and color. A star's life cycle begins as a contracting nebula and progresses through stages such as the main sequence, red giant, planetary nebula, and white dwarf before ending as a neutron star or black hole.

A star's life cycle begins as a contracting nebula and progresses through stages such as the main sequence, red giant, planetary nebula, and white dwarf before ending as a neutron star or black hole.
Space
The document discusses several celestial bodies:
- Space is the three-dimensional extent in which objects exist and have position and direction. Modern physics views it as part of a four-dimensional spacetime continuum.
- The Sun is a nearly perfect sphere of hot plasma at the center of the solar system, producing most energy for life on Earth. It accounts for over 99% of the solar system's mass.
- The Moon is Earth's only natural satellite. On average it is about 384,400 km from Earth. It is thought to have formed from debris after a collision between Earth and a Mars-sized body.
The Universe
The universe contains everything that exists, including stars, planets, and all life and matter within them. It is impossible to comprehend the universe's immense size. Our solar system contains eight planets that orbit our star, the Sun. The planets differ in their composition, with gas giants like Jupiter and Saturn composed primarily of hydrogen and helium, and terrestrial planets like Earth, Venus, and Mars made up of rock and metals. Beyond our solar system exist phenomena like asteroids, comets, and other celestial objects that have formed over billions of years since the theorized Big Bang event that created the known universe.
Stars and Galaxies
Stars are giant balls of gas that produce light and heat through nuclear fusion reactions in their cores. Astronomers can determine properties of stars like temperature, luminosity, and composition by analyzing their spectra. Stars evolve over their lifetimes, with more massive stars having shorter lives and ending as supernovae. Galaxies contain billions of stars and come in spiral, elliptical, and irregular shapes. The universe originated in a massive expansion known as the Big Bang around 13.8 billion years ago.
The Sun and our Solar System
The Sun is a middle-aged, average sized yellow star that is made up mostly of hydrogen and helium. It is about 4.6 billion years old and located 93 million miles from Earth. The Sun generates heat and light through nuclear fusion reactions in its core that convert hydrogen into helium. It is the center of our Solar System and contains over 99% of the mass in the entire system. The Solar System also includes eight official planets that orbit the Sun, along with dwarf planets, moons, asteroids, comets, and other small bodies.
Universe ppt 6 B
Galaxies contain billions of stars, gas and dust held together by gravity. The Milky Way galaxy is our galaxy and contains over 100 billion stars. Galaxies can be elliptical or irregular shapes. Our solar system consists of the sun and eight planets plus dwarf planets orbiting the sun. Planets can be inner planets like Earth that orbit close to the sun or outer planets like Jupiter that orbit farther from the sun. A light year is the distance light travels in one year and galaxies can be many light years across. The zodiac signs have roots in ancient cultures and are based on Greek myths. Constellations are groupings of stars named by ancient astronomers.

Galaxies
There are several types of galaxies including spiral, elliptical, irregular, and barred galaxies. Spiral galaxies are the most common type and have tightly or loosely wound spiral arms. The Milky Way is a typical spiral galaxy located in the outer range of the galaxy. Other galaxy types include whirlpool galaxies like M51a, barred galaxies like NGC 1365, and elliptical galaxies which can be very large or small dwarf galaxies. Irregular galaxies have no distinct shape.
Earth and Space
The document summarizes key concepts about the solar system, including:
- The solar system is made up of the sun and eight planets that orbit around it, along with moons, asteroids, and comets.
- The earth spins on its axis, causing day and night, and its tilt and orbit around the sun cause the seasons in the northern and southern hemispheres.
- Nuclear fusion in the sun's core converts hydrogen to helium, releasing enormous amounts of energy that allow it to shine.
Black holes
Black holes are regions of space where gravity is so strong that nothing, not even light, can escape. They form when large stars collapse at the end of their life cycles, compressing their mass into a tiny space. There are several types of black holes including stellar black holes formed by collapsed stars and supermassive black holes found at the center of galaxies containing billions of solar masses. If matter enters a black hole's event horizon, it becomes "spaghettified" as tidal forces stretch and compress it due to the extreme warping of spacetime.
Mars
The document summarizes key facts about the planet Mars. It describes Mars' thin carbon dioxide atmosphere, cold temperatures, lower gravity than Earth, two small moons named Phobos and Deimos, and red color caused by iron dust. It also notes that Mars has the largest volcano in the solar system, Olympus Mons, and the largest canyon, Valles Marineris. The document discusses past missions to Mars and ongoing exploration by rovers like Curiosity, which is still active on the surface.
Stars, Galaxies, and the Universe
This document provides an overview of stars, galaxies, and the universe. It begins with definitions of key terms like stars, galaxies, and the universe. It then covers the composition of stars and how they are classified. The next sections discuss the life cycles of stars and the different types of galaxies. The document concludes with an explanation of the big bang theory of the universe and how scientists estimate the age of the universe.
Star Powerpoint
Stars are formed from clouds of dust and gas collapsing under gravity. They spend most of their life fusing hydrogen into helium in their cores, glowing from the heat and pressure of nuclear fusion. When stars run out of fuel to burn in their cores, they die - smaller stars may become white dwarfs, while larger stars explode as supernovae. The material from exploded stars then disperses to form new dust clouds, starting the next generation of star formation.
Space powerpoint
The Moon is Earth's natural satellite and the fifth largest in the Solar System. It has one quarter the diameter of Earth and 1/81 its mass. The Moon is in synchronous rotation with Earth and always shows the same face.

Types of stars
This document describes different stages and types of stars:
- Main sequence stars like our Sun spend most of their lives fusing hydrogen into helium in their cores.
- Red giants are large, reddish stars that have exhausted hydrogen fusion and begun fusing helium.
- Planetary nebulae form when average-sized stars eject their outer layers after becoming red giants, leaving behind dense, hot cores called white dwarfs.
- Brown dwarfs are failed stars too small to sustain nuclear fusion.
- Variable stars change in brightness over timescales from seconds to years as they evolve.
- Binary stars are two gravitationally bound stars that orbit a common center of mass.
The Outer Planets
The outer planets are Jupiter, Saturn, Uranus, and Neptune. They are the largest planets in our solar system and are mainly composed of gases like hydrogen and helium, giving them low density. Most have a similar structure with an atmosphere of gases, a liquid hydrogen mantle, and a small molten rock core. Jupiter is the largest and has a prominent Great Red Spot storm and over 60 moons. Saturn is notable for its extensive ring system. Uranus and Neptune are both blue-green due to methane in their atmospheres.

Ch08 solar system
The Solar System formed around 4.5 billion years ago from the collapse of a giant cloud of gas and dust. The inner planets are rocky while the outer planets are gaseous. Planets formed from the accretion of planetesimals, which collided and stuck together in the protoplanetary disk surrounding the young Sun. The temperature differences in the disk led to different compositions, with rocky planets in the hot inner region and icy planets in the cold outer region. Over time, planetesimals bombarded planetary surfaces and the planets differentiated into layers. Some planets may have migrated from their initial orbits due to interactions with the gas disk.

According to the nebular hypothesis:
- The Sun and planets formed from a giant cloud of dust and gas that collapsed due to some event around 4.57 billion years ago.
- As the cloud collapsed and began rotating faster, it flattened into a disk with the Sun forming at the center.
- The terrestrial planets like Earth formed closer to the Sun from metals and rocks, while the gas giants formed beyond the frost line where ices could also form, allowing them to grow larger.
- Leftover debris that did not form planets remains in regions like the Asteroid Belt and Kuiper Belt today.

Galactic Context
The Solar System is located in the Milky Way galaxy, a barred spiral galaxy with a diameter of about 100,000 light-years containing about 200 billion stars. Our Sun resides in one of the Milky Way's outer spiral arms, known as the Orion Arm or Local Spur. The Sun lies between 25,000 and 28,000 light years from the Galactic Centre, and its speed within the galaxy is about 220 kilometres per second, so that it completes one revolution every 225–250 million years. This revolution is known as the Solar System's galactic year. The solar apex, the direction of the Sun's path through interstellar space, is near the constellation of Hercules in the direction of the current location of the bright star Vega. The plane of the Solar System's ecliptic lies nearly at right angles (86.5°) to the galactic plane.
The future of our solar system
By analyzing radioactive elements in meteorites, astronomers determined that the solar system formed 4.6 billion years ago from the gravitational collapse of a giant molecular cloud. This cloud collapsed over millions of years to form a rotating disk with the sun at the center. The planets formed from this disk, with the inner rocky planets closer to the sun and the outer gas giants farther away. In around 5 billion years, the Milky Way will collide with the Andromeda galaxy, and the solar system will be about 100,000 light years from the center of the new merged galaxy.

It also explains that the Moon is Earth's only natural satellite and formed from debris after a collision between Earth and another planetary body.

Bigbang Nucleosynthesis and evidences of big bang theory.pptx
The Big Bang theory proposes that the universe began as an extremely hot and dense singularity about 13.7 billion years ago and has been expanding ever since. During the first moments, elementary particles formed as the universe cooled and expanded. Over millions of years, simple atoms formed and later combined to create the first stars and galaxies. Evidence for the Big Bang includes the expansion of the universe, the cosmic microwave background radiation, and the relative abundances of light elements.
How the moon formed | by M.Hassaan Anjum
There are three main theories for how the Moon formed:
1. The giant impact hypothesis suggests that the Moon formed from debris ejected when a Mars-sized object collided with the early Earth.
2. The co-formation theory explains that the Moon and Earth formed at the same time from the primordial solar nebula.
3. The capture theory proposes that the Moon was initially an independent object that was later captured by Earth's gravitational pull.
Essay On Solar System For Kids
The solar system began as a giant gas cloud approximately 5 billion years ago, which then collided with another object traveling from the center of the galaxy. This collision caused a fusion reaction and created a focal point that attracted the lightest elements, primarily hydrogen, forming our Sun. Over time, the remaining gas and dust circling the new Sun condensed under gravity to form the planets, moons, asteroids and other objects that now make up our solar system.

DESIGN AND DEVELOPMENT OF LOW COST COMPUTER NUMERICAL CONTROL PLOTTER WITH AN...
Today the Growth of Technology and utilization of CNC machine are Rapid increased. Numerical control is such a useful
thing that can control a machine with numeric values and codes. That is what we call CNC machine, used in machining or any other
automation. The commercial CNCs are bulky and so much expansive and not possible to afford by normal people in home. So the
machine with computer ability and in less size mini CNCs came in. CNCs are much complex in its function. It works with the
simultaneous interpretation of software and hardware. The three axis motion is controlled by Arduino Uno board with Atmega 328p
microcontroller. The Arduino works here as an open source burner which burns the microcontroller with given hex codes. The CNC
shield along with stepper motor drivers basically receives the signals from the Arduino board and delivers the power to the stepper
motors. In this machine only G codes are used to command or instructions. G codes are language, by using this person Told computer
control machine tool. The microcontroller converts G-code into a set of machine language instruction to be sent to the motor driver of
the CNC plotter.
Silicon memory in 2018
The limits of pushing storage density to the atomic scale are explored with a memory that stores a bit by the presence or absence of one silicon atom. These atoms are positioned at lattice sites along self-assembled tracks with a pitch of five atom rows.
The memory can be initialized and reformatted by controlled deposition of silicon. The writing process involves the transfer of Si atoms to the tip of a scanning tunneling microscope. The constraints on speed and reliability are compared with data storage in magnetic hard disks and DNA.
In 1959 physics icon Richard Feynman estimated that “all of the information that man has carefully accumulated in all the books in the world, can be written in a cube of material one two-hundredth of an inch wide”. Thereby, he uses a cube of 5×5×5 = 125 atoms to store one bit, which is comparable to the 32 atoms that store one bit in DNA. Such a simple, back-of-the-envelope calculation gave a first glimpse into how much room there is for improving the density of stored data when going down to the atomic level.
In the meantime, there has been great progress towards miniaturizing electronic devices all the way down to single molecules or nanotubes as active elements. Memory structures have been devised that consist of crossed arrays of nanowires linked by switchable organic molecules or crossed arrays of carbon nanotubes with electro statically switchable intersections

Wi fi / Wireless Fidelity
WiFi stands for Wireless Fidelity. WiFiIt is based on the IEEE 802.11 family of standards and is primarily a local area networking (LAN) technology designed to provide in-building broadband coverage.
Current WiFi systems support a peak physical-layer data rate of 54 Mbps and typically provide indoor coverage over a distance of 100 feet.
WiFi has become the de facto standard for last mile broadband connectivity in homes, offices, and public hotspot locations. Systems can typically provide a coverage range of only about 1,000 feet from the access point.

- 3. The universe is everything that there is. Some people like to think of the universe as a vast container, in which everything that exists resides. However, no one knows whether or not this container is infinite in size, or if it has an "outer limit." No one knows for sure, as this question of "Is the universe finite or infinite?", has been asked for ages. Many scientists speculate that it expands outward as a balloon and has no end, continuing forever in all directions without any meaning at all. Still, some believe there is a limit and that all the galaxies and stellar objects are contained within a limited universe. This moves out of the realm of science and into the realm of metaphysics and philosophy, because there is no empirical data to suggest any conclusion as of yet. 5/7/2017 3
- 4. A galaxy is a gravitationally bound system of stars, stellar remnants, interstellar gas, dust, and dark matter. The word galaxy is derived from the Greek galaxies' (γαλαξίας), literally "milky", a reference to the Milky Way 5/7/2017 4
- 5. The Milky Way contains over 200 billion stars, and enough dust and gas to make billions more. The solar system lies about 30,000 light- years from the galactic center, and about 20 light-years above the plane of the galaxy. More than half the stars found in the Milky Way are older than the 4.5 billion year old sun 5/7/2017 5
- 6. A black hole is a region of spacetime exhibiting such strong gravitational effects that nothing—including particles and electromagnetic radiation such as light—can escape from inside it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole 5/7/2017 6
- 8. An astronomical object or celestial object is a naturally occurring physical entity, association, or structure that current science has demonstrated to exist in the observable universe. The term astronomical object is sometimes used interchangeably with astronomical body 5/7/2017 8
- 12. The Solar System is the gravitationally bound system comprising the Sun and the objects that orbit it, either directly or indirectly. Of those objects that orbit the Sun directly, the largest eight are the planets, with the remainder being significantly smaller objects, such as dwarf planets and small Solar System bodies. Of the objects that orbit the Sun indirectly, the moons, two are larger than the smallest planet, Mercury. The Solar System formed 4.6 billion years ago from the gravitational collapse of a giant interstellar molecular cloud. The vast majority of the system's mass is in the Sun, with most of the remaining mass contained in Jupiter. The four smaller inner planets, Mercury, Venus, Earth and Mars, are terrestrial planets, being primarily composed of rock and metal. The four outer planets are giant planets, being substantially more massive than the terrestrials. The two largest, Jupiter and Saturn, are gas giants, being composed mainly of hydrogen and helium; the two outermost planets, Uranus and Neptune, are ice giants, being composed mostly of substances with relatively high melting points compared with hydrogen and helium, called ices, such as water, ammonia and methane. All planets have almost circular orbits that lie within a nearly flat disc called the ecliptic. 5/7/2017 12
- 13. For instance, Earth is the third planet from the sun and the fifth largest in the solar system. Earth's diameter is just a few hundred kilometers larger than that of Venus. The four seasons are a result of Earth's axis of rotation being tilted more than 23 degrees. 5/7/2017 13
