Kepler Mission Discovers Small Planetary System
Topic: New Planets
Astronomers have discovered a new planetary system that is home to the smallest planet yet found around a star similar to our Sun. The planet, Kepler-37b, is smaller than Mercury and only slightly larger than the Moon.

Earth-Like Planets are Right Next Door
Topic: New Planets
Astronomers have reanalyzed data from Kepler and determined that many red dwarf stars are smaller and cooler than previously thought. They have also identified 95 planetary candidates orbiting these stars, with three that could be warm and Earth-sized. They estimate that six percent of all red dwarf stars could host Earth-like worlds.

The Origin and Maintenance of a Retrograde Planet
Topic: New Planets
Astronomers have revealed new details about the HAT-P-7 planetary system. The study includes the discovery of a companion star and the confirmation of a new giant planet that orbits outside of the retrograde planet HAT-P-7b.

A Rogue Planetary Orbit for Fomalhaut B
Topic: New Planets
New observations of the dusty disk and mysterious planet circling the star Fomalhaut may provide evidence for a shocking planetary disruption in the system.

Weather Patterns in a Brown Dwarf
Topic: New Planets
Astronomers have created the most detailed 'weather map' yet for a brown dwarf. The research could help scientists understand the atmospheres of extrasolar planets.

Traffic Jam of Moons in Habitable Zone
Topic: New Planets
Volunteers from the website have discovered 15 new planet candidates orbiting in the habitable zones of other stars. The finding adds to the number of strange worlds in regions around stars that could potentially support life as we know it.

Earth-Sized Planets Common in the Galaxy
Topic: New Planets
An analysis of the first three years of Kepler data shows that 17 percent of all Sun-like stars have Earth-sized planets orbiting close to their host stars. The study is good news for those searching for habitable worlds beyond our solar system.

Kepler Mission Announces 461 New Planet Candidates
Topic: New Planets
NASA's Kepler mission has announced the discovery of 461 new planet candidates. Four of the potential new planets are less than twice the size of Earth and orbit in their sun's "habitable zone."

100 Billion Planets May Populate the Galaxy
Topic: New Planets
New research provides more evidence that planetary systems are the norm. In fact, the study's authors claim that there are at least 100 billion planets in our galaxy alone.

Astrobiology Top 10: A Super-Earth in the Habitable Zone of a Six-Planet System
Topic: New Planets
As 2012 draws to a close, Astrobiology Magazine highlights the year's top stories. At number 2, researchers announced the discovery of a new super-Earth planet in the habitable zone of a nearby star dubbed HD 40307. (Orignally published on 11/07/12)
