How Low Can Life Go?
|
| Topic: Extreme Life |
06/06/08 |
| Summary: A novel, ultra-small bacterial species has been found at a depth of nearly two miles within the ice of a Greenland glacier. The ability of this organism to survive in such a unique environment will help us understand how life could survive elsewhere in the solar system. |

Illuminating Life
|
| Topic: Extreme Life |
04/24/08 |
| Summary: A small, light-weight microscope that can produce high-resolution images is being developed to help astrobiologists study microbial life in some of Earth's most extreme environments. These studies can allow scientists to determine the limits of life and will help define habitable environments on other planets. |
