How Close Are We To Colonizing Space?

How close are we to long-term human habitation beyond low-Earth orbit? Colonies on the moon or Mars are still many years off, but the good news is there are several serious efforts underway to make it happen. » 12/18/09 10:00am 12/18/09 10:00am

Ice Volcanoes of Enceladus Created By Liquid Water Beneath the Moon's…

This image from the Cassini probe shows an ice volcano erupting on the surface of Saturn's moon Enceladus. Scientists have suggested that these volcanoes might come from water beneath the moon's surface, and new evidence makes this theory more plausible. » 7/22/09 9:40am 7/22/09 9:40am

Robot Finds Melting Ice on Mars

Remember that mystery white substance that the Phoenix Lander uncovered beneath Martian soil with its robot arms? Scientists were speculating that it might be salt or it might be ice. Now, a few days later, it's looking very much like ice. Why? It's melting, as you can see in these pictures. » 6/20/08 7:00am 6/20/08 7:00am
