Kepler's Haul of Multiple-Planet Systems
|
| Topic: New Planets |
05/24/11 |
| Within just four months of data from NASA's Kepler mission, astronomers have found evidence for more than 1,200 planetary candidates. Of those, 408 reside in systems with two or more planets. |

Flipping Hot Jupiters
|
| Topic: New Planets |
05/13/11 |
| A rare number of Hot Jupiter planets orbit their stars in a direction opposite to the star's rotation. This violates basic ideas of planet and star formation. Now, new research may explain how these planets flipped their orbits. |

| New observations of '55 Cancri e' indicate that the planet is 60 percent larger in diameter than Earth, but eight times more massive. The data also indicates that 55 Cancri e orbits so close to its star that it is baked to a temperature of 4,900 degrees F. |

Tuning in to ExoPlanet Radio
|
| Topic: New Planets |
04/20/11 |
| A new study shows that emissions from the radio aurora of Jupiter-like planets should be detectable with radio telescopes. The finding means that detecting exoplanets that orbit at large distances from their star could now be easier to find. |

The Shocking Environment of Hot Jupiters
|
| Topic: New Planets |
04/19/11 |
| Astronomers have found that Jupiter-like worlds around other stars push shock waves ahead of them. Like Earth's magnetic 'bow-shock', these planetary 'shocks' can protect the atmospheres of giant planets from their star's damaging emissions. |

Titan-like Exoplanets
|
| Topic: New Planets |
04/14/11 |
| A new study says that worlds that orbit red dwarfs, and even rogue planets with no stars to call home, might have surface oceans loaded with organic compounds. Like the seas of liquid methane on Saturn´s moon Titan, such environments are speculated to have the potential for alien life. |

A Six-Planet System
|
| Topic: New Planets |
02/02/11 |
| Astronomers have used NASA's Kepler mission to discover six planets around a Sun-like star. The discovery includes five small planets and validates a new method to measure the masses of planets. The remarkable discovery could aid in the search for habitable worlds around distant stars. |

Planet Affects a Star's Spin
|
| Topic: New Planets |
01/12/11 |
| Astronomers have discovered an exoplanet that could help scientists understand how planetary systems with 'hot Jupiters' evolve. Studying the evolution of planetary systems can help astrobiologists determine where best to search for habitable worlds around distant stars. |
