Double Dust Disks
|
| Topic: Cosmic Evolution |
09/30/09 |
| Summary: Astronomers have explored one of the most compact dust disks ever resolved around another star, where an inner disk is accompanied by an outer disk. The finding may be an example of a young planetary system just entering the last phase of planet formation and could teach us about the evolution and formation of habitable planets. |

Planetary Petri Dish
|
| Topic: Cosmic Evolution |
09/29/09 |
| Summary: Astronomers have discovered a clump of planet-forming material around a distant star that looks as if it is being pushed around by another star or planet. The observation is unlike anything seen before and offers a rare look into the early stages of planet formation. |

Fun Science: Iceberg Chasing and Laser Lights
|
| Topic: Extreme Life |
09/28/09 |
| Summary: During the 2009 AMASE Expedition to Svalbard, scientists were able to carry out 'fun science' activities in addition to their normal research schedule. In this report, team member Juan Diego Rodriguez-Blanco discusses projects like 'iceberg chasing' and developing Raman spectroscopy for Mars. |

Ice Deposit Larger Than Texas
|
| Topic: Mars |
09/27/09 |
| Summary: NASA's Mars Reconnaissance Orbiter has provided 3D images of the north-polar ice layers of Mars. The images provide validation for theoretical models of Mars' climate cycles over the past few million years. With accurate climate models, scientists can help determine whether or not Mars was once a habitable environment for life. |

Meteorites Excavate Martian Ice
|
| Topic: Mars |
09/26/09 |
| Summary: NASA's Mars Reconnaissance Orbiter has revealed frozen water hiding just below the surface of mid-latitude Mars. The spacecraft's observations were obtained from orbit after meteorites excavated fresh craters on the Red Planet. |

Water on the Moon
|
| Topic: Moon to Mars |
09/25/09 |
| Summary: Using a NASA instrument housed on the Indian Chandrayyan-1 satellite, scientists have solved an Apollo-era mystery about water on the Moon. The discovery could have profound implications for future human explorers on our nearest celestial neighbor. |

Comets May Give Life a Hand
|
| Topic: Meteorites, Comets and Asteroids |
09/24/09 |
| Summary: A comet hitting Earth would seem to bring only death and destruction, but one group is studying how such an impact could promote certain necessary chemical steps in the origin of life. The researchers are focusing on how comet collisions might have influenced the molecular orientation, or handedness, of our planet's biology. |

Red Rock Tumbler
|
| Topic: Mars |
09/23/09 |
| Summary: Scientists may have a new explanation for why Mars is red. Previously, the 'red planet' was thought to have received its characteristic color due to rocks rusting in water that once flooded the planet. New research shows this may not be true. |

Cooking Life's Ingredients, with a Pinch of Salt
|
| Topic: Origin & Evolution of Life |
09/22/09 |
| Summary: By studying a chemical mixture thought to be present in the Earth's early oceans, scientists have discovered that amino acids can be 'cooked' into many other important building blocks of life when they are embedded in salt crusts. The finding could have important implications in our understanding of life's origins. |
