One thing us as humans have never been able to fully understand is astronomy. Always having an unexplained mystery, astronomy also has served as a way to keep time and predict the future. The word “astronomy” is defined as the study of heavenly bodies, meaning anything in the sky such as stars, galaxies, comets, planets, nebulae, and so on. Many people, if not everyone, is amazed by the night sky on a clear, moonless night.
Astronomy dates back to ancient times when peoples such as the Babylonians, Egyptians, and Chinese kept written records of astronomical events and occurrences. Today’s seven day week originates from the Babylonians’ seven important bodies in the night sky: the Sun, Moon, Mars, Mercury,

A wide array of instruments is used to observe heavenly bodies today. These instruments include optical telescopes which are used to magnify objects that emit visible light. Some celestial bodies are very difficult or impossible to see with optical telescopes. To see these, we use radio, X-ray, ultraviolet, or infrared instruments. An advantage of radio astronomy is the fact that radio waves aren’t stopped by the sun or clouds, therefore the stars can be observed at any time.
Our own solar system today is thought to have formed from a large, single cloud of dust and gas. The center of the cloud became dense enough and created enough energy from contraction to spark a nuclear reaction, forming the Sun. The remaining dust and ice in the cloud formed into the nine planets we know of today. Other objects within the solar system include comets, asteroids, meteorites, interplanetary dust and plasma.
Any star that we can see belongs to our own galaxy, the Milky Way. Stars do not exist outside of galaxies in empty space, rather in galaxies which are groups of billions of stars orbiting the center of the galaxy (Fradin 140). Every star has a color ranging from red to blue-white. These colors tell us many things about each star. Also, a star’s
This paper looks at the Big Bang Theory. It examines the history of the theory and the scientific ideas on which it is based. It also examines some of the evidence proving the Big Bang and addresses some of the more common arguments against it.
Astronomers study the planets, stars, and other celestial objects to try to understand how the universe works. They also study things like collisions, black holes and other things that could potentially affect earth. Astronomers gain information about objects in space from telescopes, and satellites. They can also use mathematical equations to find the positions of planets and stars in our universe. These telescopes and satellites observe light reflected by things such as planets, meteors, or stars in space and use it to make observations. Then the Astronomers job is to collect and analyze the data observed.
There are billions upon billions of stars in our galaxy but only about 2000 of those are visible to us at night. Although there is one star that we are able to see during the day, but only because it is the closest one to earth, this star is the sun. Because the brightness of the sun is so vast we cannot see other stars, but when the sun sets we can see an abundance of celestial objects. The sun appears to be what some would call “the largest star” but it is only an average sized star, there are a countless more that are hundreds times the size of our sun. When we look up into the night sky and focus our eyes on what appears to be a star we often notice it twinkling, this is caused by turbulence in earth’s atmosphere. The atmosphere is like a lens and makes a boiling effect causing stars to look like they’re twinkling. Astronomers have discovered clusters of stars forming patterns, we call them constellations and there are roughly eighty-eight in our night sky. Stars can come in all kinds of different shapes sizes and distances, which causes some stars to appear closer than others. Bigger stars tend to shine more brightly than smaller stars. Even though a star seems bigger and brighter than the others doesn’t actually mean it is, it could just be a star closer to earth than most. The closest star to us is Alpha Centauri and is approximately four light years from earth meaning it takes four years for the light from Alpha Centauri to reach
however, many crafts like the Hubble, were put in by the space shuttle. The space
Although all nine planets are a huge part of the solar system there's a lot more to the solar system than the nine planets. According to scientist the Solar System started out as an enormous cloud of gas and dust. Scientist believe that the cloud of dust and gas began to collapse under the weight of its own gravity and it did. The matter that was kept within itself began moving in a giant circle and at the center of the spinning cloud a tiny star began to form. The star eventually grew larger and collected more dust and gas that collapsed into it. Farther from the center of the mass that was being formed there was many smaller clumps of dust and gas that were also collapsing. The large cloud in the center eventually became the sun while the smaller clumps formed the planets, moons, comets and,
In this paper I will explain how astronomers determine the composition, temperature, speed, and rotation rate of distant objects using various methods. I will explain the properties of stars. I will also summarize the complete lifecycle of the Sun and determine where the Sun is currently in its lifecycle.
Answer: These people used their eyes to look at the stars, moon, and sun. They also used an astrolabe which could pinpoint and predict the moon, stars, planets, and sun’s location. This information helped them know when to plant their crops.
The solar system was believed to be formed when a gas cloud and dust in space was disturbed by the explosion of the supernova. The explosion made space waves which squeezed in the cloud of the dust. The Jovian planets include Jupiter, Saturn, Uranus and Neptune. These planets surfaces are not solid. Jovian’s atmosphere in our solar system is mostly made of helium and hydrogen.
By looking at the different wavelengths or the spectrum of light from a celestial object, you can tell many of its properties and features. To do this, the Hubble Telescope is equipped with various scientific instruments. Each instrument used
of other planets such as Saturn or Mars are a great way of studying other planets surfaces
Stars are a marvelous wonder to many people, that is why some people spend most of their lives wondering what is “above the world so high” (Gardner 98). These people study and map the little twinkling stars in order to get a better meaning of them; they are astronomers. Great astronomers like Edwin Hubble, Immanuel Kant, and William Huggins, never stopped valuing the beauty of the stars. While they developed great astronomical principals. One astronomer who fits this mold most is, Edwin Powell Hubble. Wondering about what was
NASA contributed to a number of successes in American history. During the past, the organization has rapidly acquired a number changes that has created an opportunity to expand and improve Knowledge Management (KM). Similar to many other important organizations, NASA has frequently pursued ways to capture knowledge into their information systems assuming that it could be managed best when it 's captured in a system for later retrieval. In the past 10 years, the budgets on their missions have been reduced, missions have multiplied ten-fold, and scientists and engineers have been overwhelmed by the extreme challenges. The most important factors that are addressed includes the importance of learning, (FBC) faster, better, cheaper implications, and knowledge management that supports innovation in the future.
Humans live on a small planet in a tiny part of a vast universe. This part of the universe is called the solar system, and is dominated by a single brilliant star-the sun. The solar system is the earth’s neighbourhood and the planets Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto are the Earth’s neighbours. They all have the same stars in the sky and orbit the same sun.
Indecent bodies like the sun. Stars are made up of big exploding balls of gas, mostly hydrogen and helium. The sun is similarly a star made up of huge amounts of hydrogen, undergoing a continuous nuclear reaction like a hydrogen bomb. Stars come about when vast clouds of hydrogen, helium and dust contract and collapse due to gravity. The clouds came from astronomical plasma from “The Big Bang”, but the dust comes from the supernovae of other stars.
Astronomy is the oldest of the natural sciences, dating back to antiquity, with its origins in the religious, mythological, and astrological practices of pre-history: vestiges of these are still found in astrology, a discipline long interwoven with public and governmental astronomy, and not completely disentangled from it until a few centuries ago in the Western World . In some cultures astronomical data was used for astrological prognostication.
