Waking up to a new year
Aug 26, 2013 (SPX)
In the time it takes you to complete a single workday, or get a full night's sleep, a small fireball of a planet 700 light-years away has already completed an e...
Study: Planets might be 'born free' without a parent star
Aug 20, 2013 (UPI)
Swedish astronomers say they've discovered tiny, round, cold clouds in space that have the right characteristics to form planets without a parent star. Previous...
Distant planet sets speed record by orbiting its star every 8.5 hours
Aug 19, 2013 (UPI)
U.S. scientists say an exoplanet around a distant star has one of the shortest "years" ever observed, whizzing around its parent star in a little over 8 hours. ...
Kepler planet hunter spacecraft is beyond repair: NASA
Aug 15, 2013 (AFP)
NASA said Thursday it cannot fix its hobbled planet-hunting Kepler Space Telescope and is considering what sort of scientific research it might be able to do at...
Astronomers Image Lowest-mass Exoplanet Around a Sun-like Star
Aug 07, 2013 (SPX)
Using infrared data from the Subaru Telescope in Hawaii, an international team of astronomers has imaged a giant planet around the bright star GJ 504. Several t...
New Explorer Mission Chooses the 'Just-Right' Orbit
Aug 06, 2013 (SPX)
Principal Investigator George Ricker likes to call it the "Goldilocks orbit" - it's not too close to Earth and her Moon, and it's not too far. In fact, it's jus...
'Blinking' stellar system may yield clues to planet formation
Aug 01, 2013 (UPI)
U.S. astronomers using a NASA space telescope say they've spotted a young stellar system whose developing stars cause the system to "blink" every 93 days. The s...
Pulsating star sheds light on exoplanet
Jul 31, 2013 (SPX)
A team of researchers has devised a way to measure the internal properties of stars-a method that offers more accurate assessments of their orbiting planets. Th...
Chandra Sees Eclipsing Planet in X-rays for First Time
Jul 30, 2013 (SPX)
For the first time since exoplanets, or planets around stars other than the sun, were discovered almost 20 years ago, X-ray observations have detected an exopla...
A warmer planetary haven around cool stars, as ice warms rather than cools
Jul 29, 2013 (SPX)
In a bit of cosmic irony, planets orbiting cooler stars may be more likely to remain ice-free than planets around hotter stars. This is due to the interaction o...
Solar system's youth gives clues to planet search
Jul 26, 2013 (SPX)
Comets and meteorites contain clues to our solar system's earliest days. But some of the findings are puzzle pieces that don't seem to fit well together. A new ...
In the Zone: The Search For Habitable Planets
Jul 22, 2013 (JPL)
There is only one planet we know of, so far, that is drenched with life. That planet is Earth, as you may have guessed, and it has all the right conditions for ...
A snow line in an infant solar system: Astronomers take first images
Jul 22, 2013 (SPX)
Like the elevation in the Rocky Mountains where the snow caps begin, a snow line in a solar system is the point where falling temperatures freeze and clump toge...
Snow falling around infant solar system
Jul 22, 2013 (SPX)
Astronomers using the new Atacama Large Millimeter/submillimeter Array (ALMA) telescope have taken the first-ever image of a snow line in an infant solar system...
In the Zone: How Scientists Search for Habitable Planets
Jul 22, 2013 (JPL)
There is only one planet we know of, so far, that is drenched with life. That planet is Earth, as you may have guessed, and it has all the right conditions for ...
'Water-Trapped' Worlds
Jul 19, 2013 (SPX)
A new study takes a deeper look into the fate of life-permitting water on Earth-like planets around red dwarf stars, the most common stars in the universe. Many...
Snow in an Infant Planetary System
Jul 19, 2013 (SPX)
A snow line has been imaged in a far-off infant planetary system for the very first time. The snow line, located in the disc around the Sun-like star TW Hydrae,...
UM Researchers Land NASA Grant to Search Space for Exoplanets
Jul 18, 2013 (SPX)
NASA recently awarded researchers at the University of Montana a grant to support a $1.125 million project to build a dedicated observatory to detect Earth-like...
Disks Don't Need Planets to Make Patterns
Jul 18, 2013 (JPL)
Many young stars known to host planets also possess disks containing dust and icy grains, particles produced by collisions among asteroids and comets also orbit...
Hubble Finds a Cobalt Blue Planet
Jul 12, 2013 (SPX)
Astronomers working with NASA's Hubble Space Telescope have deduced the actual color of a planet orbiting another star 63 light-years away. The planet is HD 189...
