    24. 24. INTRODUCTION CONTENT NEXT
    25. 25. Imagine yourself in a spaceship floating in space. As you look out of the window, you see nothing but a vast empty space. What do you think lies beyond this vast emptiness? Are there other heavenly bodies that exist beyond this empty void? If you look into the sky from the earth on a clear night, you may see many bright dots. Some are brighter than the others. Some are big, others are small, sometimes we asked ourselves where these things came from are? What will happen if they do not exist? BACK NEXT
    26. 26. People tried to study these heavenly bodies, which became vital to man. With the knowledge given by the modern ways of discovering new things, mans have fewer fears about all things surrounding them. He began to understand that even the outer space is part of his environment, just mountains and oceans are. This Workbook is designed to give and reveal to you the magic and amazing secrets of our Solar System. BACK HOME

    49. 49. MODULE 1: ORIGINS OF THE SOLAR SYSTEM CONTENT NEXT
    50. 50. So we observed a clear night sky, thousands of stars and few hazy patches of light can be seen. We then realize the vastness of the outer space and wonder how the Solar System came into being. In this Chapter, we will find out the different origins of the Solar System. OBJECTIVES: <ul><li>To be able to know the different origins of the Solar System </li></ul><ul><li>To differentiate each origins </li></ul><ul><li>To observe and describe the different theories of the Solar System </li></ul>BACK HOME

    52. 52. OBJECTIVES: <ul><li>To state the Big Bang Theory </li></ul><ul><li>To infer what really this theory all about </li></ul><ul><li>To illustrate the Big Bang Theory </li></ul>LET’S KNOW THIS Big Bang Theory is like a fireball and exploded and threw out particles of matter in all directions. It asserts that as a star approached the sun, a cosmic accident took place. BACK NEXT
    53. 53. According to the standary theory, our universe sprang into existence s singularity around 13.7 billion years ago where singularities are zones which defy our current understanding of physics. They are thought to exist at the core of black holes. Black holes are areas of intense gravitational pressure. The pressure is thought to be intense that finite matter is actually squished into infinite density. Tidal bulges formed on the surface of the sun, condensed and where ejected into space. The ejected materials became the planets and planetoids that revolved around the sun. BACK NEXT
    54. 54. These zones of infinite density are called singularities. After its initial appearance, it apparently inflated, expanded and cooled, going from very, very small and very, very hot, to the size and temperature of our current universe. It continues to expand and cool until the solar system is being a part of it and we are inside of it, an incredible creatures living on a unique planet, circling a beautiful star clustered together with several hundred billion of other stars. BACK NEXT
    55. 55. TRY TO STUDY THIS BIG BANG THEORY BACK NEXT
    56. 56. Big Bang Theory is like a fireball exploded and threw out particles of matter in all directions.

    62. 62. Did you explain the Big Bang Theory based on your own understanding? If you did, then Great!!! Let’s go now to our next topic, the Planetisimal Theory. BACK HOME
    63. 63. LESSON 2: PLANETISIMAL THEORY CONTENT NEXT
    64. 64. OBJECTIVES: <ul><li>To define Planetisimal Theory </li></ul><ul><li>To be aware on this theory </li></ul><ul><li>To draw and illustrate the Planetisimal Theory </li></ul>LET’S KNOW THIS Planetisimal Theory states that the sun, a big star, collided with the small star. The impact of the collision causes the ejection of particles into space. These particles later became the members of the Solar System. The planets form out of dust grains that collide and stick to form larger and larger bodies. BACK NEXT
    65. 65. When the bodies reach sizes of approximately one kilometer, then they can attract each other directly through their mutual gravity, aiding further growth into moon-sized protoplanets enormously. This is how planetisimals are often defined. Bodies that are smaller than planetisimals must rely on Brownian motion or turbulent motions in the gas to cause the collisions that can lead to sticking. Alternatively, planetisimals can form in a very dense layer of dust grains that undergoes a collective gravitational instability in the mid-plane of a protoplanetary disk. BACK NEXT
    66. 66. Many planetisimals may eventually break apart during violent collisions, but a few of the largest planetisimals can survive such encounters and continue to grow into protoplanets and later planets. It is generally believed that by about 3.8 billion years ago, after a period known as the Late Heavy Bombardment, most of the planetisimals within the solar system had either been ejected from the solar system entirely, into distant eccentric orbits such as the Oort cloud, or had collided with larger objects due to the regular gravitational nudges from the Jovian planets (particularly Jupiter and Neptune). A few planetisimals may have been captured as moons of the Jovian planets. BACK NEXT
    67. 67. TRY TO STUDY THIS PLANETISIMAL THEORY BACK NEXT
    68. 68. The Planetisimal theory states that the big star collided with the smaller star and ejected particles that later become member of the Solar System. TRY TO REMEMBER THIS How much have you learned? Do you really understand the lesson? Then, let’s check your comprehension. Can you do the following activities? BACK NEXT
    69. 69. LET’S DO THIS ACTIVITY 3 Name: ___________________ Score: _________________ Grade and Section: _________ Date: __________________ DIRECTION: True or False.

    73. 73. Did you understand the Planetisimal Theory? Then if you did, Good!!! Now let’s move to our next topic, The Nebular Theory. BACK HOME
    74. 74. LESSON 3: NEBULAR THEORY CONTENT NEXT
    75. 75. OBJECTIVES: <ul><li>To explain the Nebular Theory </li></ul><ul><li>To compare this theory to other two theories </li></ul><ul><li>To picture out the Nebular Theory </li></ul>LET’S KNOW THIS Nebular Theory states that the sun, planet and moon were formed at about the same time from a notating mass of hot gases and dust line ten billion years ago. BACK NEXT
    76. 76. According to this theory, rings of hot gases were developed and were shed off. As the gases cooled and condensed, they broke off into fragments to form the members of the Solar System. It was first proposed in 1973 by Emanuel Swedenborg. Originally applied only to our own Solar System, this method of planetary system formation is now thought to be work through out the Universe. Star formation is a complex process, which always produces a gaseous protoplanetary disk around the young star. This may give birth to planets in certain circumstances, which are not well-known. BACK NEXT
    77. 77. Thus, the formation of planetary system is thought to be a natural result of star formation. A sun- like star usually takes around 100 million years to form. The Nebular Theory is also called Dust Cloud Theory. BACK NEXT
    78. 78. LET’S STUDY THIS NEBULAR THEORY BACK NEXT
    79. 79. Nebular Theory states that the sun, planet and moon were formed at about the same time from a notating mass of hot gases. The gases that cooled and condensed cause them to broke and later form a member of Solar System. LET’S REMEMBER THIS How much have you learned? Do you really understand the lesson? Then, let’s check your comprehension. Do the following activities. BACK NEXT

    84. 84. MODULE 2: THE SUN AND ITS LAYERS CONTENT NEXT
    85. 85. At daytime, the sun shines so brightly that the light are given off by other stars are overpowered. The sun is the only visible on earth. It overpowers the light coming from other stars. Why is this so? Why does the sun is the only visible star on earth during daytime. In this module, we will unfold the different layers of the sun. OBJECTIVES: <ul><li>To be familiar with the characteristics of the sun </li></ul><ul><li>To appreciate the different functions of the sun </li></ul><ul><li>To picture out the different layers of the sun </li></ul>BACK HOME
    86. 86. LESSON 1: PHOTOSPHERE CONTENT NEXT
    87. 87. OBJECTIVES: <ul><li>To distinguish the different layers of the Sun </li></ul><ul><li>To be aware of these different layers </li></ul><ul><li>To illustrate/draw its layers </li></ul>Photosphere is the visible surface of the sun. it is also called the “light-emitting layer”. Above the photosphere sunlight is force to disseminate into space and its energy escapes the sun completely. BACK NEXT LET’S KNOW THIS
    88. 88. Sunlight has approximately a black-body spectrum that indicates its temperature is about 6 000 K, interspersed with atomic absorption lines from the tenuous layers above the photosphere. The photosphere has an element density of about 1023/m3 (this is about 1% of the particle density of Earth’s atmosphere at sea level). The parts of the sun above the photosphere are referred to collectively as the solar atmosphere. BACK NEXT
    89. 89. LET’S OBSERVE THIS PHOTOSPHERE BACK NEXT
    90. 90. They can be seen with telescopes across the electromagnetic spectrum, from the visible light to gamma rays. As we look down into the atmosphere at the surface of the Sun the view becomes more and more opaque. The point where it appears to become completely opaque is called the photosphere. Thus, the photosphere may be thought of as the imaginary surface from which the solar light that we see appears to be emitted. The diameter quoted for the Sun usually refers to the diameter of the photosphere. Radiation emitted from the photosphere accounts for most of the solar energy flux at the Earth. BACK NEXT

OBJECTIVES: <ul><li>To know what is Chromospheres </li></ul><ul><li>To be aware on color sphere </li></ul><ul><li>To picture out the illustration of Chromospheres </li></ul>LET’S KNOW THIS BACK NEXT Chromosphere is a thin layer present above the visible surface on photosphere, which is about 2000 km. thick specifically dominated by a spectrum of emission and absorption lines. It is called the chromospheres because t comes from the Greek root “chromos” meaning “color”. Another term for chromospheres is the color sphere, for this reason, the color sphere is visible as a colored flash at the beginning and the end of total eclipse of the sun.
    102. 102. The term “chromospheres” was first applied to the red ring and large prominences seen at the edge of the eclipsed Sun with the unaided eye. Emission in the Balmer-alpha line of hydrogen at 653-nanometer wavelength accounts for the red color. The solar chromospheres extends from roughly 500 km (300 mi) above the photosphere to where hydrogen becomes fully ionized and the gas temperature rises rapidly to more than 106 K (1.8 × 106 °F) in the corona. Stars with effective temperatures less than about 8000 K (14,000°F; the Sun is 5770 K or 9930°F) show the same emission lines as the solar chromospheres and are thus thought to have analogous regions.

OBJECTIVES: <ul><li>To determine what is Corona </li></ul><ul><li>To differentiate Corona to other layers </li></ul><ul><li>To show the illustration of the outermost layer of the </li></ul><ul><li>sun </li></ul>LET’S STUDY THIS The Corona is the outer atmosphere of the sun, which is much larger in volume than the sun itself. The Corona merges slickly with the solar wind so as to fill the solar system and heliosphere. BACK NEXT
    112. 112. The low Corona, which is very close to the surface of the sun, has a particle density of 1011/me ( Earth’s atmosphere near sea level has a particle density of about 2 x 1025/m3 ). The temperature of the Corona is several million degrees Kelvin. The Laws of electromagnetism prohibit the intersection of two magnetic field lines, every time magnetic field lines come cross to crossing, they are “rearranged” and this magnetic reconnection continuously heats the solar corona. As a direct consequence of this theory, the heating process should occur much closer to the surface of the sun than previously thought, but no one really knows how close. BACK NEXT
    113. 113. The corona can be seen during solar eclipses, when the main radiation from the sun’s surface is blocked by the passage of the moon. One of the most puzzling features of the sun is what has been dubbed “the solar corona problem”. There is a region around the sun, existing more than one million kilometers from its surface, where the temperature can reach two million degrees. This region, called the Solar Corona, is where the solar wind originates. BACK NEXT
    114. 114. LET’S OBSERVE THIS CORONA BACK NEXT

OBJECTIVES: <ul><li>To briefly explain the innermost layer of the sun </li></ul><ul><li>To be aware of what we called Core </li></ul><ul><li>To illustrate its features </li></ul>LET’S STUDY THIS The Core is the innermost layer of the sun and it is a source for all the sun’s energy. The material in the core is firmly attached and has very high temperature, which is about 15 million degrees Kelvin. In the core, the intense heat destroys the internal structure of an atom and therefore all atoms are broken down into their constituent parts. An atom is composed of protons, electrons and neutrons. BACK NEXT
    123. 123. The charge neutral material of protons and electrons that makes up the core called plasma. Thermonuclear reactions takes place inside the core, thus hydrogen atoms are combined with each other to make the helium atoms and produces energy which keeps the sun in a state of equilibrium. Thus, this thermonuclear reaction is called nuclear fusion. BACK NEXT
    124. 124. The Central Core decays, electromagnetic waves on the surfaces of the core include normal elementary particles that create an envelope of material that surrounds the core. The major source of the sun’s energy is the decaying central core. In essence, almost every particle of material that exists in the envelope, the sun-excepting particles pulled in by gravity is created, that is induced by the electromagnetic field on the surface of the core of the sun. BACK NEXT

It has many craters on its surface. Mercury has no atmosphere to protect it from the sun or from meteorites. BACK NEXT
    136. 136. Mercury’s axis is the straightest of the planets, with the least “tilt”. This is the reason why Mercury has only one season. Mercury is not an easy planet to find in the sky because it stays close to the sun. You can sometimes see it in the east just before sunrise or in the west just after the sunset. It looks like a pinkish star. Even through a telescope, you can make out few details of the planet’s surface. Mercury is covered with craters and looks much like the moon. The major difference between the two bodies is that Mercury has no large flat plains or seas, like the moon. BACK NEXT
    137. 137. It is believed that Mercury resembles very much the Moon (its diameter is almost as twice as the diameter of Earth's only satellite). Its surface carries the signature of heavy asteroid and meteorite bombardment that took place since its early ages, recognizable by the huge amount of craters of all sizes that dots the surface. Mercury basically doesn't have any atmosphere, so the 'sky' surrounding it is always black. BACK NEXT

It is the hottest planet. It is the brightest object in the sky, except for the moon. BACK NEXT
    149. 149. Venus is the easiest to recognize. On many evenings at sunset we see it shining brightly in the western sky as the evening star. At another times we see it shining in the eastern sky at dawn as the morning star. Venus shines brighter than any other planet for two reasons. First, it is the planet that comes closest to the Earth, sometimes within 26 million miles. Second, it is permanently covered with thick clouds, which reflect sunlight brilliantly. In size, Venus is near twin of the Earth, being only slightly smaller. It also has atmosphere. It is relatively close to us in the Solar System. We might think, therefore, that Venus would be a similar planet to the Earth but nothing could be farther from the truth. BACK NEXT
    150. 150. Venus rotates backwards, from East to West. Venus’ days are longer than its years! Its year is 224 Earth days, its days last 243 Earth days.

OBJECTIVES: <ul><li>To be able to know our own planet and its moon </li></ul><ul><li>To understand Earth revolve around the sun </li></ul><ul><li>To illustrate how moon revolve around the Earth </li></ul>LET’S KNOW THIS Earth is our home. It is the only place in our Solar System where plants, animals and people can live. To survive, we need air and water as well as heat and light. The air we breathe is made up mostly nitrogen and oxygen. These gases and others make up the Earth’s atmosphere. BACK NEXT
    163. 163. The atmosphere protects us from meteorites and harmful radiation from space. It also helps keep Earth from becoming too hot or too cold. Earth’s water comes from oceans that cover two-thirds of our planet. Earthquake, floods and erosion are always changing the surface of the Earth. Earth spins on its axis like a top, once a day, at a speed of about 10,000 miles an hour at the equator. Everything around us on Earth –building, trees and animals—spins at the same speed so we don’t notice that Earth is moving. As the Earth spins, the sunlight spins in different parts of our planet at different times. This creates day and night. BACK NEXT

    165. 165. LET’S STUDY THIS OUR MOON Our moon is our closest neighbor in the Solar System. It is about 250,00 miles away from us. Its surface is dry. Is has no air, we can see its mountains and craters from Earth. We know a lot about our moon because USA has sent six man expeditions to explore it. Like Earth, our moon spins on its axis. It also revolves around the Earth and the sun. Reflected lights from the sun light up different parts of our moon in different phases. BACK NEXT
    166. 166. A Solar Eclipse happens when the moon travels between the sun and planet Earth. This stops sunlight from shining on part of our planet. A Solar Eclipse happens about once every three or four years. When our moon is in the Earth’s shadow we have lunar eclipse. Earth travels around the sun in an orbit shaped like an oval (something like the shape of an egg). Our planet looks blue from space, because there is so much water on Earth. From Earth, we sometimes can see details on the moon’s surface by using binoculars or a telescope. The moon becomes as hot as 248 degrees Fahrenheit and as cold as –320 degrees Fahrenheit temperature that are much hotter and much colder than those on Earth. BACK NEXT

Mars tends to give off a reddish hue when viewed from Earth. This is believed to be caused by the abundance of iron oxide on the planet’s surface. BACK NEXT
    178. 178. It is the planet that is most like Earth. It has a ice caps at the North and South poles. It is similar to Earth in some respects. A day on Mars is only slightly longer than our own day. The planet has an atmosphere and it also has seasons like the Earth, only they are almost twice as long as ours. However, Mars is different from the Earth in most other ways. It lies much farther from the sun and is much colder. It has only a very thin atmosphere, made up mainly of carbon dioxide gas. BACK NEXT
    179. 179. Mars can be easily seen from Earth without telescope at a brightness that is only surpassed by the planet Venus, the moon and the sun. Mars has long been considered the most realistic location for life in our solar system, aside from Earth. Many believe that intelligent life may have once existed on the planet.

Jupiter is the fourth brightest object in the sky after the Sun, moon and Venus. The prehistoric times know Jupiter as a bright “wandering star”. BACK NEXT
    189. 189. The voyager probes also found that Jupiter has a very strong magnetic field. This field extends far out into space and traps electrified particles in large donut-shaped regions. These regions are source of intense radiation that could pose a real danger to space travelers in the future. Jupiter also has a ring that is similar to the kinds of rings Saturn has, which are made up of small lumps of rocks and ice whizzing around the planet at high speed. BACK NEXT
    190. 190. Jupiter's four large moons Io, Europa, Ganymede and Callisto (now known as the Galilean moons) and recorded their motions back and forth around Jupiter. This was the first discovery of a center of motion not apparently centered on the Earth. Jupiter and the other gas planets have high velocity winds which are confined in wide bands of latitude. The winds blow in opposite directions in adjacent bands. Slight chemical and temperature differences between these bands are responsible for the colored bands that dominate the planet's appearance. The light colored bands are called zones; the dark ones belt. BACK NEXT

    200. 200. OBJECTIVES: <ul><li>To explain why Saturn has rings </li></ul><ul><li>To expand their knowledge about Saturn </li></ul><ul><li>To differentiate Saturn to other planet </li></ul>LET’S STUDY THIS Saturn is the second largest planet. Its rings are made of thousands of ringlets of dust, water, ice and very small particles. It is unusual in the sense that they are composed of materials, which are similar to those of the sun. They actually emit more energy than the amount they receive from the sun. They are estimated to contain more than 90% of the mass of the Solar System outside the sun. Saturn is made up mostly of hydrogen, a light gas. BACK NEXT
    201. 201. Saturn’s moon, Titan, is the second largest moon in the Solar System. Titan’s atmosphere, like Earth, is made up mostly of nitrogen. Saturn is the most distant planet we can see in the naked eye, but we need a telescope to see its rings. Large telescopes reveal that its disk is crossed with parallel bands,, but they are much fainter than those on Jupiter. Saturn, then, is a smaller and paler version of Jupiter and is thought to be much like Jupiter in make up. It too has a strong magnetic field and radiation belts. BACK NEXT
    202. 202. Saturn named after the Roman god of agriculture, the planet Saturn is the sixth planet in order of distance from the sun, and the second largest planet in the solar system. Saturn is most usually thought of for its ring system. The Italian scientist, Galileo was the first to spot Saturn's rings in 1610, using one of the first telescopes. Discovered in 1655 by the Dutch astronomer Christian Huygens, Titan is the biggest of the 31 known moons orbiting Saturn. It is a cold world enclosed by a thick, hazy atmosphere impenetrable by telescopes and cameras. BACK NEXT

OBJECTIVES: <ul><li>To extend our knowledge about Uranus </li></ul><ul><li>To be aware on its different characteristics </li></ul><ul><li>To picture out the illustration of Uranus </li></ul>LET’S STUDY THIS Uranus was the first planet to be discovered through a telescope. It is the only planet that rotates on its side! It is tilted at an angle of almost 98 degree. The mysteriously tilted planet of Uranus is one of the 4 gas giants, or planets whose gas composes the majority of its mass. BACK NEXT
    217. 217. The planet Uranus is the seventh from the sun. Its 51,117km diameter classifies it as the third largest planet in the solar system. By mass, Uranus is the fourth largest. Despite not being certain how the planet Uranus inherited its 98° axial tilt; we are able to study the effects of this uneven heating. Hypotheses suggest this unique aspect is due to a major collision during formation. John Flamsteed first recorded the planet in 1690, but believed it was a star. Almost 100 years later in 1781, Sir William Hershel made the formal discovery. BACK NEXT
    218. 218. Although originally mistaking it for a comet, Hershel quickly corrected his error and established Uranus as a planet. Uranus was named after the Greek god of the sky. Although there are no current plans to physically explore Uranus, the planet was visited in 1986 by the NASA spacecraft, Voyager 2. The surface composed of rock and ice is surrounded by an atmosphere of hydrogen, helium and methane. Uranus’ average temperature is -218°C, or -360° F. So far thirteen rings surrounding Uranus have been found. BACK NEXT

It is the only visited by one spacecraft on August 25, 1989. Neptune comes from this single encounter but fortunately have added a great deal too because Pluto orbits is so eccentric, it sometimes crosses the orbit of the Neptune. BACK NEXT
    232. 232. Making the Neptune the most distant planet from the Sun for the few years. Neptune composition is probably similar to Uranus various “ ices ” and rock with about 15 % hydrogen and a little helium. Because Neptune is so far away, little was known about it until Voyager 2 sped by it in 1989. The planet is a deep blue color and shows interesting features, such as dark spots and white wisps. Neptune has also a set of faint rings around of it. This means that all four giant planets have ring system, but only Saturn’s rings can be seen from Earth. BACK NEXT
    233. 233. Neptune winds are the fastest in the solar system reaching 2000 km/hour. Neptune most prominent feature was the “ Great Dark Spot ”, the southern hemisphere and also the “ Smaller Dark Spot” popularly known as “The Scooter ”. On 1994 the dark spot has disappeared but a few months later the new dark spot discovered on the Northern Hemisphere. This indicates that Neptune’s atmosphere changes rapidly. BACK NEXT

Among the numerous of heavenly bodies are the asteroids which number about 30,000. Asteroids are found between the orbits of Mars and Jupiter. They are believed to be fragments of an exploded planet. BACK NEXT
    248. 248. Asteroids are composed of rocks and metals. Ceres is the biggest asteroid with a diameter of about 800 kilometers. Then very little is known about these bodies by astronomers with diameter from 16 to 160 kilometers. Asteroids are rocky and metallic objects that orbit the sun but are too small to be considered planets. They are known as minor planets. They are material left over from the formation of the solar system. One theory suggests that they remains of a planet that was destroyed in the massive collision long ago. Astronomers have studied a number of asteroids through Earth-based observations. Several notable asteroids are Tautahs, Castalia, Geographo and Vesta. BACK NEXT

They revolve around the sun in elongated elliptical orbits at regular intervals. A comet has a head composed of small rock fragments, dust and some gases. Its head is less dense than the Earth’s atmosphere. Like planets, comets shine because they reflect sunlight. BACK NEXT
    260. 260. A comet develops tail as it approaches the sun. The intense heat exerts a pressure on the particles in the head. The tail always points away from the sun. Most comets are estimated to require about 10,000 years to complete one circuit of the sun. A great majority of comets we observe will not be visible again from the Earth for thousands of years. There are many historical records and works of art which record the appearance of comets and link them with terrible events such as wars and plagues. Now we know that comets are lumps of ice and dust periodically come into the center of the solar system from somewhere in its outer reaches and that some comets make repeated trips. When comets get close enough to the sun , heat makes them start to evaporate. BACK NEXT

OBJECTIVES: <ul><li>To briefly narrate what is meteor </li></ul><ul><li>To extend our awareness about meteorites </li></ul><ul><li>To illustrate the picture of meteors </li></ul>LET’S KNOW THIS Meteors are rocks that fly into the atmosphere of the Earth. These rocks are made of iron and nickel. These objects in space are also called shooting stars. Meteors are believed to have come from tails of comets or from small fragments of asteroids Meteors travel in space of about 40 kilometers per second. This friction with the air causes meteors to glow brilliantly. BACK NEXT
    271. 271. However, the effects are not seen below an altitude of 15 kilometers. When there are numerous meteors, a meteor shower occurs. Upon reaching the Earth’s atmosphere, most meteors vaporize. Those that do not burn completely and fall on Earth are called Meteorites. Most of the meteors seen during one of the annual showers arise from fluffy particles not much larger than sand grains as the particles enters Earth atmosphere, it collides with the gas atoms and molecules. The particles becomes wrapped in a glowing sheath of heated air and vaporized material boiled off its own surface. Meteors become visible at altitudes between 50-75 miles with faster particles typically shining at greater heights. BACK NEXT
    272. 272. Many of the faster, brighter meteors may leave behind a train – a dimly glowing trail that persists for many seconds or, more rarely , minutes. Larger debris may create a fireball. Occasionally a fireball will fragment. Such fireball is called a bolide. BACK NEXT

    286. 286. As the star collapses in size, it continues to cool. It then becomes faint until it cannot be seen anymore. A collapsing star may suddenly flare up and become thousands of times bigger. It is called a nova. It is the last stage and is about to die. After such brilliance, the star collapses and finally dies. Stars do not really twinkle. They appear to twinkle because we see them through layers of air surrounding Earth as their light passes through the air layers, the light’s speed changes as it moves from one layer to another.

    288. 288. Do you have an idea how many stars are visible on a clear night. LET ’ S KNOW THIS LET ’ S KNOW THIS LET’S KNOW THIS BACK NEXT
    289. 289. Only about 2500-3000 stars can be seen with the unaided eye at any time, but there are still billions of stars that can be seen with the aid of powerful telescopes. They vary in brightest, depending on their distance from the earth, their size and their temperature. BACK NEXT
    290. 290. Like us, stars have their own life cycle. They born and they die. They do not live forever. A star is a large ball of hot gas, emitting large amount of radiant energy from nuclear reactions in its interior. It is thousands to millions of kilometers in diameter. BACK NEXT
    291. 291. Stars evolve from hydrogen gas found in interstellar medium called Nebulae. The mass of gas contract within a nebula. The hot ball begins to glow and it is the birth of a new star. During the early stage of the star’s evolution, the temperature rises due to nebular reaction within the stars. The young star then becomes a mature white star, like the sun. Eventually a star will undergo a new series of internal reactions that will cause it to expand. When most of the nuclear fuel is consumed, the star will pulsate and finally contract to a cooling white dwarf. BACK NEXT

    293. 293. SIZE, COLOR AND TEMPERATURE LET’S KNOW THIS Stars vary in size. A star can be a super giant, a giant, or a dwarf. Antares and Betelgeuse are examples of super giants. Pegasus is a giant and our sun is a dwarf. BACK NEXT
