April 24th, 2007 Article Summary #10 “Out of our world: Earth-like planet” By: Dan Vergano April 24, 2007 USA TODAY A group of European astronomers just discovered that there may be the first habitable Earth like planet outside our solar system. The conditions of the planet are much like Earth. Oceans and life may be possible. The planet orbits the red dwarf star Gliese 581 in a Goldilocks orbit that can withstand temperatures between 32 and 108 degrees Fahrenheit. There are more than 200 planets that are detected nearby, most of which are gas giants. This new discovery shadows earth’s features, such as rocky terrain and its distance from its star to harbor oceans. NASA is in search for life elsewhere and is very excited that there is a new class of planets like earth. Gliese 581 is 20.5 light years away in the constellation Libra and completes a year in 13 days.

Unformatted text preview: Astronomer, Alan Boss said, This is the closest planet to another earth that has been found to date, and the fact that have liquid water makes it even more fascinating and arguably the first habitable planet. The planet was ultimately discovered by measuring the back and forth wobbles that the orbiting planets bring on. Gliese 581c is about five times heavier than Earth and twice as wide. Astronomers are excited for the beginning of the search for extraterrestrial intelligence and have radios that survey Gliese 581 for radio signals but have yet to find anything. Water will be the key as to whether life could exist on Gliese 581c, and determining, with a telescope, whether oceans exist there will be tricky, Tarter says. I think that humans have the answer but will never share for fear of a religious revolution....
