Racing to Picture a Planet
|
| Topic: New Planets |
12/05/07 |
| Summary: A new instrument may help astronomers see past the glaring light of stars in order to take direct pictures of exoplanets. Such technology will help us view planets around distant stars and determine whether or not they could be habitable for life as we know it. |

And Then There Were Five
|
| Topic: New Planets |
11/07/07 |
| Summary: Astronomers have discovered a fifth planet circling the star 55 Cancri – a record number of confirmed planets for a star beyond our Solar System. The new planet is probably similar to Saturn, except that it rests within the 'habitable zone' of its parent star. |

|
| Topic: New Planets |
10/09/07 |
| Summary: Astronomers have spotted a star system 424 light-years away where they think an Earth-like planet is likely forming. They've found a belt of warm dust that has enough mass to form a planet the size of Mars or larger. |

Large but Light
|
| Topic: New Planets |
08/10/07 |
| Summary: Astronomers have found the largest extrasolar planet to date. The planet, dubbed TrES-4, is about 70 percent bigger than Jupiter but has a very low density. In fact, TrES-4 is much larger relative to its mass than astronomers had thought possible, and studying the planet will provide new insight into how planets form and behave. |
