After 11 years of NASA research a red dwarf star, gliese 581g has been looked at a lot closer and it is pretty much another Earth. After looking at pictures of it I thought it was just a picture of Earth but it's not.
This planet is not freezing like all the planets past mars that range from -200 through -400 degrees. And it is not hot like Venus and Mercury that are in the 800's.
It has been said that Mars has dry river beds and other dried up bodies of water which once supported life. The only water on Mars is frozen from the cold which at its lowest is -190 degrees.
On gliese 581g an atmosphere is capable of being held because the gravity is strong enough, but the star that would be this planets "Sun" does not get circled like Earth does to the Sun. Because of that, the lighted side of this planet will always be the lighted side and the dark side will stay dark. If we were to live on this planet we would have to be on the border so we don't freeze or burn but stay at a decent temperature.
Here's a more detailed article from NASA about this http://www.nasa.gov/topics/universe/features/gliese_581_feature.html
This could be interesting if we lived there but it is 20 light years away. so if we traveled at the speed of light for 20 years then there we go.
I'm excited about...
Passing this class and getting it over with.
I'm not excited about...
Having to do work.
