Another Earth?

Scientists think they found 5 planets around Tau Ceti, a star located 12 light-years from us. Among the planets, one would be located at a distance from the star that could allow life on its surface.

Here is the article.

What kind of life?

This subject came up elsewhere recently. They had a checklist of all the things that would need to happen just right to allow anything more than microbial life to evolve.

One possible point was to suggest that the odds of another intelligent species evolving elsewhere in the universe at the same time as humans remain a species here on earth, is really very low, so we don't need to worry about them invading us.

Another possible point was to imply that maybe humans need to take better care of the planet we've got because realistically, we don't have a lifeboat!
