How much water would a self-sustaining moonbase need?

As humanity returns to the moon in the next few years, they're going to need water to survive. While resupplies from Earth would work for a time, eventually the lunar base would have to become self-sustaining? So, how much ...

Chandra X-ray Observatory's clear, sharp photos help astrophysicist study energetic black holes

When a star is born or dies, or when any other very energetic phenomenon occurs in the universe, it emits X-rays, which are high-energy light particles that aren't visible to the naked eye. These X-rays are the same kind ...
