The Galaxy's Rosy Glow
|
| Topic: Cosmic Evolution |
04/11/07 |
| Summary: Astronomers have determined that a mysterious red glow seen throughout the Milky Way but never on Earth may be caused by fine dust containing a previously unknown molecule. The research sheds new light on the chemistry behind organic molecules in space. |

Sunset on Tatooine
|
| Topic: Cosmic Evolution |
03/31/07 |
| Summary: The double sunset that Luke Skywalker gazed upon in the film "Star Wars" might not be a fantasy. Astronomers working on the search for distant, Earth-like planets have observed that planetary disks, which harbor asteroids, comets and possibly planets, are at least as abundant in twin-star systems as they are in single-star systems like our own. |

Fingerprinting the Milky Way
|
| Topic: Cosmic Evolution |
03/25/07 |
| Summary: Astronomers are using the chemical signatures of stars to determine which formation sites they have in common. The research will help unravel the history of the Milky Way and ultimately it can teach us about how galaxies form and evolve. |

The Birth of the Sun
|
| Topic: Cosmic Evolution |
02/25/07 |
| Summary: Astronomers have gazed at the embryo of an infant star that may one day develop into a virtual twin of our own Sun. The finding may be a rare opportunity to understand how the early Sun developed and shaped the environment of our solar system. |

Sol Sister
|
| Topic: Cosmic Evolution |
02/20/07 |
| Summary: By studying a star similar to the Sun, astronomers find that the cycle of activity our Sun undergoes is typical of Sun-like stars. The research is valuable in understanding our Sun's behavior and how it affects climate change on Earth. |

Swooping Under the Sun
|
| Topic: Cosmic Evolution |
02/10/07 |
| Summary: The Ulysses spacecraft has reached maximum latitude in its exploration of the heliosphere, the bubble in space blown out by the solar wind. The craft's position provides a unique look at the Sun and how it affects the environment of the Solar System. |

Hot Windy Nights
|
| Topic: Cosmic Evolution |
01/17/07 |
| Summary: New measurements for three planets outside our solar system indicate their temperatures remain fairly constant - and blazing hot - from day to night, even though it is likely one side of each planet always faces its sun and the other is in permanent darkness.

Checking Out the Stellar Neighborhood
|
| Topic: Cosmic Evolution |
01/15/07 |
| Summary: A recent study found 20 new star systems in the sun´s local neighborhood. Most of the new discoveries are red dwarfs, much smaller and dimmer than the sun. Yet scientists are growing more confident that these stars could host habitable planets. |

From Snowballs to Planets
|
| Topic: Cosmic Evolution |
01/14/07 |
| Summary: A nearby star only 12 million years old is surrounded by a dusty disk reminiscent of the disk from which the Earth and other planets formed more than 4.5 billion years ago. Peering into this dusty disk, astronomers have found that the dust is as fluffy as powder snow. |
