What Can You See in the Night Sky? For starters, you can see the moon, stars, constellations and even some planets. This article is about some of what the night sky holds. There are some pretty amazing things out there, just waiting to be seen! Many of these things can be seen with the naked eye. Going through college I was always a Science geek and took Astronomy as an elective course. This is a little bit about Astronomy and the night sky.
One of the major things we all see in the night sky is stars. Stars are balls of cosmic energy. They can produce heat, light, and other forms of radiation. They are made up mostly of gas and plasma. The stars we see vary in their intensity, due to the distance they are from us and can also be due to how

The Sun is the star that is closest to the Earth, and is the source of a great deal of our energy. The fusion of hydrogen ( H) and helium (He) is part of what gives the sun or any star its shine. This happens when energy is released during the reaction.
Polaris or the North Star is the largest star in the constellation Ursa Minor. It is actually one larger star and two smaller stars. It is the North Star because of its close proximity to the north celestial pole. Ursa Minor is known as the "Little Bear", the tail of which is called the "Little Dipper" because of its ladle like appearance.
The moon is the only natural satellite of earth. In terms of the whole solar system, the earth's moon is the fifth largest of all the moons. As the moon rotating around earth, the same face of the moon always faces earth. Forces from tides make the moons rotation stay in sync with its revolution around earth. The complete orbit of earth takes place approximately every 28 days.
The Moon consists of a crust, core and mantle. The moon is thought to have formed from magma ocean crystallization. Much of its surface is rocky and full of craters and it can't support water and therefore, it can't support

The Milky Way consists of a core region surrounded by gas, dust and stars. The sun, earth and planets are located in one of the spiral arms of the Milky Way. The gaseous planets are the gas giants, Jupiter, Saturn, Uranus and Neptune. The other four planets are terrestrial planets. These are Mercury, Venus, Earth and Mars. Jupiter is the 5th planet from the sun and is the largest planet. Saturn is the 6th planet from the Sun and the 2nd largest after Jupiter.. This planet can actually be seen from Earth with the naked eye. Uranus is the 7th planet from the Sun and is the 3rd largest. It is named after the Greek deity of the sky. Uranus is the first planet to be discovered by the telescope. Neptune is the 8th and furthest planet from the sun. It is named for the Roman god of the sea. Earth is the 3rd planet from the Sun and is the 5th largest in the solar system. Home to humans and many species, earth is the only known place in the universe where life exists. Mars is the 4th planet from the sun. It is named after Mars, the Roman god of war. It is also called the "Red Planet" because of its red appearance. Venus is the 2nd largest planet to the sun. It is named after the Roman goddess of love. Venus is 2nd only in brightness after the moon Mercury is the innermost planet and smallest planet in the Solar System. Mercury orbits the sun once every 87 days or so. It is similar in appearance to the earth's moon.
I was born with an inherent fascination for all things celestial. Ever since I was young, I have been staring at the night sky trying to find constellations, or using my juvenile imagination to create my own. My efforts to find, view, and mentally catalogue everything the heavenly bodies have to offer has led me to employ some over-the-top measures, but the most extreme of them all might be the night I stayed awake through the wee hours of the morning to catch a glimpse of a meteor shower. Over the course of an entire year, the memory of this stupefying event is still as lucent and vivid as it was that very night so long ago.
The moon is mentioned abundantly in the scripture, many researches say the phases of the moon have a direct relationship with what occurs around the world. Judy Isacoff writes "The phases of the moon are a significant part of our experience of life on Earth." According to NASA, one ...
Stars are born and reborn from an explosion of a previous star. The particles and helium are brought together the same way the last star was born. Throughout the life of a star, it manages to avoid collapsing. The gravitational pull from the core of the star has to equal the gravitational pull of the gasses, which form a type of orbit. When this equality is broken, the star can go into several different stages. Some stars that are at least thirty times larger than our sun can form black holes and other kinds of stars.
The Sun is a huge, bright sphere that is mostly made up of gas that is about 5 billion years old. The Sun is the closest to the Earth, it is 145 million km distant (this distance is called an Astronomical Unit). The next closest star is 300,000 times further away. There are probably millions of similar stars in the Milky Way galaxy (and even more galaxies in the Universe), but the Sun is the most important to us because it supports life on Earth.
The moon is very different from Earth. An example is gravity. Not only gravity but also the surface; the moon’s surface is very different and harsh compared to earth. Just going to the moon is dangerous; imagine surviving
There are five basic theories in the formation of our moon. The first is the "fission theory" which states that the moon was once a part of earth, but separated a long time ago. The second theory is called the "capture theory". This theory is says that the moon formed somewhere else, and was "captured" by earths gravitational pull. The third theory is called the "condensation theory" this theory states that the moon and earth were condemned together from the original nebula that formed our solar system. The fourth theory called the "Colliding Planetesimals Theory" states that the interaction between the earth orbiting the sun, and the sun orbiting planetesimals, which are large Astroid like rocks, led to the breakup and formation of our moon from the debris of these planetesimals. The fifth and final theory is called ...
Located in the southern hemisphere, it was included in Ptolemy's 48 constellations in the second century, and is recognised among the 88 today. It contains 8 main stars and has 32 stars with Bayer/Flamsteed designations. These unseen stars come from a cluster known as M41 which is about 2,300 light years away. Even a small telescope will reveal the swarm of several thousand stars just under Sirius. Canis Major's second-brightest star is Adhara, placed within the Dogs leg. Adhara is 425 light years away, and were it to be the same distance from the Earth as Sirius, it would shine 200 times brighter. Also, if our eyes were tuned to Ultraviolet light, Adhara would outshine every other star in the sky due to it emitting more UV rays than visible
...lieve that millions of years ago, a piece of rock as big as Mars hit the Earth, and the collision blasted a huge amount of rock into space, and the shattered pieces of rock went into orbit around the Earth. Over millions of years, the rocks clumped together to form the moon, and now it is not the pieces of rock that orbit the Earth, but the moon itself. Scientists, Native Americans, and many other people have their theories of how the moon became, but none have been proven. Scientists have studied the moon for many years, and have proven many theories, but not this one.
Even with all the technology we have today, scientists still do not know exactly how the moon was formed. There are many theories, but that is all that they are. Two of the biggest, most supported theories are that of the planet Theia and the theory that the moon was formed from loose debris, from Earth's formation, gathered together by gravity. Although, no matter how the moon was formed, all life on Earth benefits from having it. Not only does it affect living animals, humans, and plants, but non-living things too! There are many facts about the moon, and with those facts comes knowledge of benefits.
Human fascination with the stars is as ancient as Babylonians and has been suggested to be older than Stonehenge. From “be fruitful and multiply” to “live long and prosper,” the instinct to protect and propagate the species has manifested in religion, art, and the imaginations of countless individuals. As human understanding of space treks out of the fantastical and into the scientific, the realities of traveling through and living in space are becoming clearer. Exploring, investigating, and living in space pose an expansive series of problems. However, the solutions to the problems faced by mankind's desire to reach beyond the horizon, through the night sky, and into the stars are solutions that will help in all areas of life on Earth.
The Sun is very special because it’s the only fixed star that can produce light and heat itself. Others, such as the Planets, satellites and asteroid can only reflect the light, which they get from the Sun. It’s not doable for them to produce their own light and heat. The distance between the Sun and the Earth is the average of 149,600,000 km. It’s ‘average of’ because the distance are not always the same. The diameter of the Sun is about 1,391,000 km, which is 109 times the Earth and the mass is 33 times the Earth. However, the average density is only a quarter of the Earth, 1.41g/cm3. This is because the Sun is made of gas unlike the Earth, which is solid. The temperature of the Sun’s surface is about 5,600ºC and the center of the Sun reaches 15,000,000ºC.
Our solar system has eight planets, their moons and satellites, and they are all orbiting the Sun. The eight planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Pluto used to be the ninth planet but IAU changed the definition of planet and Pluto did not meet the standards so it is now a Dwarf planet.
Ever since the beginning of time there have been stars. Not only stars in the sky, but moons, planets, and even galaxies! Astronomy is defined as the branch of science that deals with celestial objects, space, and the physical universe as a whole. In other words it is the study of space, planets, and stars. Throughout the ages, many people have used astronomy to help them learn about the universe, our own planet, and even make predictions about life itself. Understanding astronomy means understanding where it originated, the different groups/cultures that used it, and modern purposes of the science of the stars.
The moon is an important part of our everyday lives but yet we don't know the real reason for the formation of our natural satellite. Therefore, people have created multiple theories about how it was made with evidence and support. There are many different opinions on this topic and only the best ones are accepted. The moon will forever be a mystery to the world.
