If and when robotic spacecraft or human explorers reach the surface of Jupiter's icy moon Europa, they could begin exploring it based on data collected by a team of Russian experts currently digging their way into Lake Vostok.
This particular lake is very special. Buried under 2 miles (3.7 kilometers) of Antar... |

Using data supplied by a NASA spacecraft, a team of experts at the University of Colorado in Boulder (UCB) was recently able to determine that global sea levels rose by 0.5 inches (12 millimeters) between 2003 and 2010. Though this may not seem like much, experts provide frightening statistics.
They say that the vol... |

An interesting phenomenon discovered in Antarctica left scientists baffled. They discovered that members of a set of teardrop-shaped lakes can move very fast across the landscape, at a speed of up to 1.5 meters (5 feet) each day. A walking lake, you might say, how preposterous!
That was my initial reaction as well,... |

The Pine Island Glacier, known among experts as PIG, is one of Antarctica's five largest ice streams, and one of the most important ice fields in the world. During a study conducted at the location by NASA scientists, back in October 2011, a huge crack was found scarring its surface.
This is nothing but bad ne... |
