Titan.
Saturn's Moon Titan has special fascination to astrobiologists.

Exotic Life Could Survive on Titan.

Saturn's Moon Titan has long held a special fascination to astrobiologists. Its thick atmosphere is largely composed of nitrogen and organic molecules which are the building blocks of life. At a frigid -178 C (-289 F), however, it's much too cold to support life. But there could be some habitable locations on Titan, you just have to look carefully. Methane clouds around Titan indicate that it probably has an active cycle similar to the water cycle here on Earth. There could be areas where get warm enough on Titan for life to gain a foothold.

Planets Are Born Quickly.

The time frame for the formation of new planets appears to be getting shorter than previously believed. Astronomers have discovered gaps in protoplanetary disks that suggest there are Gas giants forming there. One star, GM Aurigae, is a younger version of our own Sun and the gap in its disk is at about the same location as our own gas giant planets. Since GM Aurigae is only 1 million years old, these results challenge the traditional theories that planets slowly formed over many millions of years.

Most Distant Explosion Ever Seen.

An Italian team of Astronomers have found a gamma ray burst that blew up 12.7 billion light-years away - the most distant ever seen. Astronomers have calculated that it exploded with 300 times more energy than our Sun will put out in its entire 10+ billion year lifespan. The blast was discovered by NASA's Swift satellite, which is dedicated to discovering these powerful explosions.
