Deep Space Objects

  The universe contains many different types of object like moons, planets, stars, nebulae, and galaxies. Ancient man has been fascinated with the stars, planets and galaxies that filled the night sky. Many such cultures depicted drawings on the cave walls, stone tables or whatever media they could find. These cultures such as the Sumerian's, Egyptians, Chinese, Native American Indians, Mayans, Babylonians, Australian Aboriginals, and many others, all tell the same story and draw similar pictures. These stories dealing with the "Gods" conquests, battles, entertainment and lust, while man being only a "Pawn" in the great cosmic chess game.

Stars

  The stars come in many different sizes, types and temperatures. Today scientist have learned much about the stars and how they work. Scientist study stars to learn more about the universe and how our own star the sun works. Stars have different temperatures, ranging from about 2,100 °C (about 3,800 °F) up to 50,000 °C (about 90,000 °F).

  Stars can also have other stars in orbit with each others, this is known as a double star or binary star. One such double star is Sirius and its much fainter companion (known as Sirius B) revolving around it. There are also stars that have two double stars in orbit around each other (that's two stars revolving around each other orbiting two other stars revolving around each other). This type of system is known as a binary star system. This would be like moons revolving area planets, revolving around the two suns.

Nebulae

  When a star begins to die, its fate depends on how much mass it has. As a stars use up all the hydrogen in their interiors, and can no longer fuse hydrogen into helium, they can no longer fight off gravity, and their interiors begin to collapse. During the contraction, their outer layers are pushed off. The larger the stars mass the larger pushed off gases and material become over time. Nebulae can range in many different types and sizes (like the background on this page known as Crab Nebulae).
