Scientists are particularly interested in Saturn's moon Titan because it's one of the few known moons with its own dense atmosphere. Titan's atmosphere is also thought to be very similar to what Earth's atmosphere was a long time ago. By learning about Titan, we'll learn about our own planet.

Orphan 'planet' findings challenged by new model

Planet-sized objects floating freely among the stars may not be planets at all. According to Alan Boss of the Carnegie Institution of Washington, the objects may have formed the same way that stars form. They may be extremely small brown dwarfs—star-like objects too small to ignite.
