Hot Topic Deep Space New Planets
 
The Commonality of Earths
Topic: New Planets
12/15/09
Summary: Astronomers have discovered as many as six low-mass planets around two nearby, sun-like stars. The findings indicate that low-mass planets could be common around nearby stars.

Seeing Planets in the Glare of a Star
Topic: New Planets
12/05/09
Summary: Astronomers have made the first direct detection of a planet-like object orbiting a sun-like star. The finding is a step forward for scientists searching for habitable worlds around distant stars.

Hunting for Planets in the Dark
Topic: New Planets
11/19/09
Summary: A proposed space mission that aims to measure dark energy could also detect planets that current surveys are unable to find.

32 New Exoplanets Found
Topic: New Planets
10/20/09
Summary: Astronomers have reported 32 new exoplanets discovered using the HARPS spectrograph for ESO's 3.6-meter telescope. HARPS has provided a boost in the number of planets that are only a few times more massive than Earth. Some of these low-mass planets rest close to the habitable zone of their host stars.

Cloudy, with Pebble Showers
Topic: New Planets
10/03/09
Summary: A newly-discovered exoplanet has an atmosphere that contains the same ingredients as rocks. In fact, a storm on COROT-7b may include pebbles condensing out of the air to rain into lakes of lava. COROT-7b is less than twice the size of Earth and can help astronomers understand how small, rocky planets form and evolve.

Confirming a Hot Earth
Topic: New Planets
09/18/09
Summary: Scientists have confirmed the existence of a solid, rocky planet orbiting a distant star. The research also revealed a second Super Earth in the same solar system. Studies like these bring us closer to the discovery of habitable exoplanets similar to Earth.

New Planet Orbits Backwards
Topic: New Planets
08/16/09
Summary: Scientists have discovered a new planet that orbits its host star backwards. The finding casts new light on how planetary systems form and evolve.

The Rise and Fall of Planetary Light
Topic: New Planets
08/09/09
Summary: NASA's Kepler telescope has detected the atmosphere of a known gas giant planet orbiting a distant star. The finding demonstrates the telescope's scientific capabilities, which will help astrobiologists search for habitable worlds beyond our solar system.

Astrometry Finally Finds a Planet
Topic: New Planets
06/02/09
Summary: Astrometry is a method of detecting planets by precisely measuring the motion of stars as planets tugs them back and forth ever so slightly. The technique was first attempted 50 years ago, but has failed to turn up any extrasolar planets until now.

The Velocity of Planets
Topic: New Planets
05/12/09
Summary: Researchers have developed a new technique to detect small, extrasolar planets that are more Earth-like than the majority of planets discovered thus far. They call it the "astro-comb", and it could help astrobiologists in the search for distant, habitable worlds.
