This essay tells about the constellation Aquarius. It focuses both of the mythological history of the constellation, and of the stars which make up the constellation.

it is how utopia affected astronomy over time

Discusses research and theories on UFOs. Questions the reliability of eyewitness accounts. Details the events of UFO sightings in the modern era.

Edwin P. Hubble was a ground-breaking American astronomer who revolutionized our knowledge of the universe and established the foundations for all of modern cosmology. At the beginning of the 20th century, most astronomers thought that our Universe was confined to the Milky Way Galaxy alone. However, Edwin Hubble's inspiration and perseverance in astronomical research proved otherwise. He discovered the existence of other galaxies and created a systematical classification for all galaxies. Additionally, he mathematically confirmed that his newly discovered universe was expanding. Hubble's astronomical triumphs earned him worldwide scientific honors and pioneered our modern cosmology.

Explains many interesting facts about Jupiter. Gives everything from basic knowledge to complex detailed facts.

Nearly all the matter in the universe is concentrated in galaxies. A galaxy is a gigantic mass of stars held together by gravity.

Provides biographical detail on Italian physicist and astronomer Galileo Galilei. Contends that he founded modern science. Discusses some of his more famous discoveries, including changing the worldview of how the sun revolved around the earth.

Various views on the cosmos were held by several different groups of philosophers, but the two most popular views were held were held by some of the more remembered philosophers, such as the famous Pythagoreans, who supported the geocentric theory and Aristarchus, who supported the heliocentric theory. The geocentric view is the view that the Earth is placed at the centre of the universe with all the heavenly bodies circumnavigating it. The heliocentric view caused much dispute as it opposed the bible. (The bible supported the Earth being at the center of the universe, Geocentric)

Discusses the phenomenon of light. Describes how Light reflects off of certain colors to allow colors to be seen. Questions what is light spectra, who found light spectra, how is light spectra used to classify stars, how is light spectra measured, and what is used to measure light spectra?

The future of living on the Moon is near. This subject was once a joke, but now it is a not so distant reality. Colonizing on the Moon is the stepping stone to exploring the rest of the universe.

Provides a study of Reflection Nebulaes. Examines reasons why most reflection nebulaes are blue and why Nebulaes brightness depends on the mass and density of the star.

Provides a biography of the astronomer Nicolas Copernicus. Describes his education and early interest in astronomy. Explores his observations, books and other works. Details how his work affected other future scientists.

While the cost of continued space exploration is a controversial issue, our past explorations have had a lasting impact on humankind. The international space station, the Hubble Space Telescope, and the DNanlyzer have all enhanced our research, and space exploration has also improved our quality of life and created jobs for Americans. Continuing such exploration is vital not only to the advancement of society, but to our very existence as well.

Questions if it is possible for humans to colonize Earth's Moon. Describes what life on the moon might be like.

The story of how the Hubble Telescope came to be. The telescope that orbits the Earth has helped advance studies of the planets and universe.

The life span of a typical star covers millions, billions, even tens of billions of years. Through their observations, however, astronomers have been able to put together a star's life cycle from its creation to its death.

Essay consists of a discussion about the Sun.

Describes the Sun, how it works and how it affects our world. Explains how the sun is the center of the universe and compares it to other stars in the solar system. Explores the future of the sun and its finite resources.

Describes the Big Bang Theory, Heliocentric Theory, Geocentric Theory, Galactacentric Theory, and finally Kepler's Law of Planitary Motion.

An overview of the Big Bang Theory, with evidence to support it. The theory holds that the universe emerged from an explosion of a highly dense microscopic particle containing concentrated energy.

This essay is a short, science fiction story. It is about a asteroid about to hit the planet Korthus.
