May 08, 2012 (SPX)
University of Warwick astrophysicists have pinpointed four white dwarfs surrounded by dust from shattered planetary bodies which once bore striking similarities...
Looking for Earths by looking for Jupiters
May 08, 2012 (SPX)
In the search for Earth-like planets, it is helpful to look for clues and patterns that can help scientist narrow down the types of systems where potentially ha...
Three Earthlike planets identified by Cornell astronomers
Apr 27, 2012 (SPX)
It's not little green men, but it could be a step in that direction: Cornell astronomers, using data from the NASA Kepler Mission, have identified three Earthli...
Some Stars Capture Rogue Planets
Apr 20, 2012 (SPX)
New research suggests that billions of stars in our galaxy have captured rogue planets that once roamed interstellar space. The nomad worlds, which were kicked ...
UF-led team uses new observatory to characterize low-mass planets orbiting nearby star
Apr 13, 2012 (SPX)
Astronomers have found compelling evidence for two low-mass planets orbiting the nearby star Fomalhaut, just 25 light years from Earth. Twice as massive as the ...
Study On Extrasolar Planet Orbits Suggests That Solar System Structure Is The Norm
Apr 12, 2012 (SPX)
Recently, the HARPS spectrograph and the Kepler satellite made a census of the planetary population around stars like our own, revealing a bounty of planetary s...
When Stellar Metallicity Sparks Planet Formation
Apr 11, 2012 (SPX)
In new research, scientists have attempted to determine the precise conditions necessary for planets to form in a star system. Jarrett Johnson and Hui Li of Los...
NASA Extends Kepler, Spitzer, Planck Missions
Apr 09, 2012 (JPL)

A planetary system from the early Universe
Apr 04, 2012 (SPX)
A group of European astronomers has discovered an ancient planetary system that is likely to be a survivor from one of the earliest cosmic eras, 13 billion year...
Getting to Know the Goldilocks Planet
Apr 03, 2012 (SPX)
NASA's Kepler spacecraft is discovering a veritable avalanche of alien worlds. Recent finds include planets with double suns, massive "super-Earths" and "hot Ju...
Discovery of an 'alien earth' imminent?
Apr 03, 2012 (UPI)
The first planet that can be considered a true "alien Earth" will probably be discovered in the next two years, a NASA scientist says. Astronomers have so far f...
Billions of Habitable Zone Rocky Planets Could be Orbiting Red Dwarf Stars
Mar 29, 2012 (SPX)
A new result from ESO's HARPS planet finder shows that rocky planets not much bigger than Earth are very common in the habitable zones around faint red stars. T...
Runaway Planets Zoom at a Fraction of Light-Speed
Mar 26, 2012 (SPX)
Seven years ago, astronomers boggled when they found the first runaway star flying out of our Galaxy at a speed of 1.5 million miles per hour. The discovery int...
Some orbits more popular than others in solar systems
Mar 23, 2012 (SPX)
Computer simulations have revealed a plausible explanation for a phenomenon that has puzzled astronomers: Rather than occupying orbits at regular distances from...
Kepler Statistical Analysis Suggests Earthlike Planets Extremely Rare
Mar 15, 2012 (SPX)
Last week, the Kepler science team released its list of candidate planets based on the data collected during the mission's first sixteen months. The last compar...
Herschel's new view on giant planet formation
Mar 15, 2012 (ESA)
Astronomers have used ESA's Herschel Space Observatory to observe 2M1207, a peculiar brown dwarf with its own circumstellar disc and a planetary companion five ...
Star Comb joins quest for Earth-like planets
Mar 09, 2012 (SPX)
If there is life on other planets, a laser frequency comb developed at the National Institute of Standards and Technology (NIST) may help find it. Such a comb-a...
Researchers say galaxy may swarm with 'nomad planets'
Mar 02, 2012 (SPX)
Our galaxy may be awash in homeless planets, wandering through space instead of orbiting a star. In fact, there may be 100,000 times more "nomad planets" in the...
New model provides different take on planetary accretion
Mar 02, 2012 (SPX)
The prevailing model for planetary accretion, also called fractal assembly, and dating back as far as the 18th century, assumes that the Solar System's planets ...
