ACEIZE Tracking the current state of Science and Technology

The star, Gliese, located within the Libra constellation was in the news about a year ago as Astronomers found a roughly earth sized planet within the habitable zone of the star.

This year, Gliese's planets are in the news again. This time talk is centered around Gliese 581 d and Gliese 581 e. E is too hot. D, may be just right. Gliese 581 D has the proper size for it's gravitational pull to retain water. That planet's orbit is also within the habitable zone of it's star so water shouldn't burn off or constantly freeze.
