Planet V was a fifth terrestrial planet that lay just beyond Mars. About 3.9 billion years ago, it was pulled out of orbit by the gravity of its neighbors, disrupting the asteroid belt before being pulled into the Sun and destroyed.

Scientists seeking to determine whether life one existed on Mars believe that the perennially frozen lakes of Antarctica may provide the answer.

According to astrophysicist Dr. Christopher McKay and biologist Dr. Robert Wharton of the Ames Research Centre at the University of California at Berkeley, the Antarctic lakes resemble some that existed on Mars in the distant past. Life has been found in Antarctica; could there once have been life on Mars?

On Saturday, the European Space Agency and its Rosetta space probe, made some history. The Rosetta passed the Lutetia asteroid and the OSIRIS camera took some amazing pictures.

The Lutetia is the largest asteroid that has been recorded in this fashion. Over 282 million miles from Earth, past Mars, the Lutetia and the Rosetta came within almost 2000 miles of each other. They passed each other at speeds of approximately 9 miles per second. The OSIRIS camera took pictures for several hours. These pictures are the most detailed, of its kind, ever captured.
