| Amino Acids: In Hot Water |
| Topic: Meteorites, Comets and Asteroids |

| Meteorites shower the Earth with amino acids. A new project is exploring how long amino acids could survive on asteroids, meteorites, and the early Earth. The results could help scientists pinpoint how and where life on our planet began. |

| The planet Jupiter is thought to act as a "cosmic vacuum cleaner," sucking up comets and asteroids that could potentially hit the Earth and endanger all life on our planet. But new research has more closely examined Jupiter's ability to protect the inner solar system, and there are some suprising findings. |

| Can life travel from planet to planet? From Astrobiology Magazine, European Edition comes a story about the possibility of Panspermia. This theory says that meteorites could act as miniature spaceships, carrying microorganism passengers. But a new study has found that photosynthetic life probably wouldn´t survive the journey. |

| When scientists examined a meteorite from Mars under a microscope, they discovered tiny mineral spheres that, some argued, were produced by living organisms. Now, researchers working in the high Arctic have found similar mineral features, produced not by microbes, but by a volcano. |

| Scientists have analyzed some of the particles captured by NASA's Stardust mission and returned to Earth earlier this year. And they've found a big surprise. Although the particles come from a comet that formed in the deep-frozen outer reaches of the solar system, they contain minerals that could only have been created near the sun. |

| Samples of the comet Wild 2 will come down to Earth on January 15, 2006. But what kind of shape will they be in? Worries about the sample return capsule's parachutes - and memories of the Genesis mission - add nail-biting drama to the event. |
