Gliese 581c is the second planet located in the Gliese 581 system 20 light years away. Gliese 581c has a chance of supporting life. But later calculations show that Gliese 581c could have an environment similar to Venus. If that is true, it cant support life as we know it. It might be extremophiles however in the upper atmosphere of Gliese 581c.
