Planets Need Heavy-Metal
|
| Topic: New Planets |
07/26/03 |
| Astronomers have previously estimated that around five percent of stars may have planets, but a survey by Berkeley planet finders has refined this classification. If a star is rich in metals, particularly iron and other heavy metals, then it stands a remarkable one-in-five chance of also hosting planets. |

Ancient Planet Discovered
|
| Topic: New Planets |
07/14/03 |
| Using the Hubble Space Telescope, astronomers have identified the oldest and most distant known planet orbiting two burned-out stars. Its sky location in the constellation Scorpius places the planet as the M4 globular cluster. The discovered world is also the only planet found to orbit around a binary star system. |

Similar Solar System at 90 Light Years
|
| Topic: New Planets |
07/07/03 |
| Astronomers have found the first sun-like star with a giant gas planet in an orbit similar to Jupiter's. At a distance of 90 light-years, the similar solar system to ours means that this gas giant could attract most of the dangerous impact debris. |
