Earth-Like Planets are Right Next Door
|
| Topic: New Planets |
02/06/13 |
| Summary:
Astronomers have reanalyzed data from Kepler and determined that many red dwarf stars are smaller and cooler than previously thought. They have also identified 95 planetary candidates orbiting these stars, with three that could be warm and Earth-sized. They estimate that six percent of all red dwarf stars could host Earth-like worlds. |

Breaking Through the Antarctic Ice
|
| Topic: Extreme Life |
02/02/13 |
| Summary:
For the first time, scientists have successfully drilled through 800 meters of Antarctic ice to retrieve water and sediment from an isolated, subglacial lake. The samples will teach astrobiologists about life in extreme environments on Earth, and possibly on icy worlds in the Solar System. |
