Trio of Neptunes
|
| Topic: New Planets |
05/21/06 |
| Summary: Using the ultra-precise HARPS spectrograph on ESO's 3.6-m telescope at La Silla (Chile), a team of European astronomers have discovered that a nearby star is host to three Neptune-mass planets. The innermost planet is most probably rocky, while the outermost is the first known Neptune-mass planet to reside in the habitable zone. |

Icy Super Earth Found
|
| Topic: New Planets |
03/14/06 |
| Summary: An international team of astronomers has discovered a "super-Earth" orbiting in the outer region of a solar system 9,000 light-years away. Weighing 13 times as much as Earth, with a temperature of minus 330 degrees Fahrenheit, the planet is one of the coldest ever discovered outside our solar system. |

Planets in the Vortex
|
| Topic: New Planets |
03/08/06 |
| Summary: The University of Arizona College of Optical Sciences is developing devices that block out starlight, allowing astronomers to study planets in nearby solar systems. The core of this technology is an "optical vortex mask" that spins light like wind in a hurricane. |

A New Class of Planet?
|
| Topic: New Planets |
07/13/05 |
| Summary: Last August, two groups of scientists announced the discovery of the smallest extrasolar planets found to date. But just what are these Neptune-size worlds? Are they gas giants, ice giants, or oversized Earths? Astronomer Alan Boss examines the possibilities. |
