A Tale of Planetary Woe
|
| Topic: Mars |
11/11/09 |
| Summary: Some scientists believe that a relatively wet and warm ancient Mars may have been a second location for life. However, Mars did not end up as a planet filled with the multitude of life we see on Earth. NASA's new Mars orbiter, MAVEN, may help astrobiologists understand why. |

Frost-Covered Phoenix
|
| Topic: Mars |
11/10/09 |
| Summary: NASA's Mars Reconnaissance Orbiter has captured images of the Phoenix lander shrouded in dry-ice frost on Mars. Phoenix has been inactive since the completion of its mission in November 2008. Early next year, scientists will try to contact the lander to see if it is still able to communicate. |

Uracil Made in the Lab
|
| Topic: Origin & Evolution of Life |
11/08/09 |
| Summary: NASA scientists have reproduced uracil, a key component of the hereditary material, RNA. The uracil was created by exposing an ice sample containing the molecule pyrimidine to ultraviolet radiation under space-like conditions. The research may help astrobiologists understand how molecules for the origin of life were first made. |

Unsettled Youth
|
| Topic: Cosmic Evolution |
11/07/09 |
| Summary: NASA's Spitzer Space Telescope has discovered a young star where young planets jostle about like unsettled children. The system may be similar to our own solar system before our planets settled into their familiar orbits. |

Think Global, Act Local
|
| Topic: Climate |
11/06/09 |
| Summary: Recently, Astrobiology Magazine's climate blog, The Hot Zone, spoke with Dr. Anastasia Romanou, Associate Research Scientist at NASA GISS, about the need for precise local measurements of climate phenomena. Local measurements can provide information about the real impacts of climate change. |

Mercury Rising
|
| Topic: Mercury |
11/04/09 |
| Summary: On its final flyby of Mercury, NASA's Messenger spacecraft has captured images of never before seen regions of the planet. Messenger is providing new scientific findings about the closest planet to the sun, and teaching astrobiologists about how rocky planets form and evolve. |

Primitive Particles
|
| Topic: Meteorites, Comets and Asteroids |
11/03/09 |
| Summary: Scientists have discovered 'ultra-primitive' material in stratospheric dust samples collected by high-flying aircraft. The material likely wafted into the atmosphere of Earth as our planet passed through the tail of a comet, and could help scientists understand the early solar system and the role that comets may have played in life's origins. |
