Mercury experiences extreme temperatures‚ as the days and nights are so long. Jupiter‚ Saturn‚ Neptune‚ and Uranus have no solid surface i.e. they have a gaseous surface. Pluto is very far away. Comets and asteroids have too little gravity for a surface colony‚ although some have suggested that an asteroid could be hollowed out. This is

Lori Mares 03/07/13 Exploration in Space Space exploration has been around for a long time ever since the first rocket went into space. That was the work of the Germans after world war II. The competition to be the first in space began in 1945 and would last 30 years. The Space Race pitted the United States and Soviet Union against each other in a contest that extended from the Earth to the surface of the moon and beyond. Humans have dreamt of exploring space for a very long time. Centuries

On March 4‚ 2010‚ a panel of 41 scientists agreed that the Chicxulub asteroid triggered the mass extinction. Although‚ several impact craters such as in the Deccan Traps may have caused it. With such a catastrophic The Chicxulub Crater in Mexico event as this‚ evolution is sure to occur because of it. Charles Darwin’s

Search for Extraterrestrial Life Introduction Mankind has always wondered‚ "Are we alone in the Universe? Isn’t there life out there somewhere?" With an estimate around 300 billion stars in the Milky Way galaxy alone‚ many with their own satellites‚ the possibilities seem likely that some form of life should exist somewhere in the Universe. This search for life begins with a definition of life itself‚ followed by possible candidates both within and outside our solar system‚ and also includes
