Titan Shrivels like a Raisin
|
| Topic: Titan |
08/14/10 |
| Scientists have been trying to figure out how mountains form on Saturn's moon, Titan. The best explanation may be that Titan is shrinking as it cools, wrinkling the surface like a raisin. Understanding physical processes on Titan can help astrobiologists determine the potential for life on the unique, frigid moon. |

Watching Titan's Lakes Rise and Fall
|
| Topic: Titan |
07/18/10 |
| Scientists have found evidence of lake-level changes on Saturn's moon, Titan. Titan is the only world aside from Earth than is known to have a hydrological cycle. Studying Titan's hydrology can help astrobiologists understand how such cycles operate beyond Earth, and could have implications for theories about strange life on the unique moon. |
