 * Ask an Astrobiologist: Comet Elenin ||  ||   ||
 * Ask an astrobiologist provides visitors with answers to the many questions in this field. This particular page on the web site addresses the issue of the comet Elenin. Many people were concerned about the impact of this comet causing destruction on earth and it has been tied to the 2012 Doomsday hoax. Here an astrobiologist gives you the facts about this comet and whether or not it poses a threat. He provides you with an expertise that will assist you in understanding the truth from the myths about the comet. ||

 * Deep Sleep in Deep Space for Europe’s Comet Chaser ||  ||   ||
 * The hibernation of the Rosetta comet chaser was planned for June 2011 and is expected to last until January 2014. This article tells you all about this hibernation period. You will discover that during hibernation, Rosetta will reach its maximum distance from the Sun and Earth. You will also learn what UK scientists and engineers are hoping Rosetta will be able to tell them about comets including their origin. The past success of Rosetta is also discussed and you can view images and watch a video on comet investigation. ||

 * Comets ||  ||   ||
 * This web site provides viewers with an excellent overview about comets. Learn that comets are lumps of ice and rock that periodically come into the center of the solar system from somewhere in its outer reaches, and that some comets make repeated trips. Jets of gas and dust form long tails that we can see from Earth. View incredible comet images and learn many more interesting facts about the comets of the past, present, and future. There is even an opportunity to color-a-comet for younger viewers. ||

 * Isaac Newton 1643-1727 ||  ||   ||
 * Discover what it was that helped Isaac Newton develop his theory of gravity. This report lists the four main discoveries that made Newton one of the world's most influential scientists and explains how Newton claimed the falling of apples influenced his work. It also reveals what scientists believe was the inspiration for Newton's theory for gravity, explains the reasoning behind this belief, and tells you why the idea most likely came from a comet, not from falling apples ||

 * Dirty Iceballs ||  ||   ||
 * Comets are made of small chunks of ice and particles of dirt, which is why they are referred to as dirty iceballs in this article. You can learn all about comets including how they are formed, how and where they move, and where they originate. You will find information on comet orbits and uncover a common myth, learn about comet classification including short-period and long-period comets, and also the exploration of comets with specific examples. ||
