First potentially habitable Earth-sized planet confirmed by Gemini and Keck observatories
"What makes this finding particularly compelling is that this Earth-sized planet, one of five orbiting this star, which is cooler than the Sun, resides in a temperate region where water could exist in liquid form," says Elisa Quintana of the SETI Institute and NASA Ames Research Center who led the paper published in the current issue of the journal Science.

Astronomers discover Earth-sized planet in habitable zone
Notre Dame astrophysicist Justin R. Crepp and researchers from NASA working with the Kepler space mission have detected an Earth-like planet orbiting the habitable zone of a cool star. (2014-04-18)

Vitamin B3 Might Have Been Made in Space, Delivered to Earth by Meteorites
Ancient Earth might have had an extraterrestrial supply of vitamin B3 delivered by carbon-rich meteorites, according to a new analysis by NASA-funded researchers. (2014-04-18)

First Earth-Size Planet Is Discovered in Another Star's
A team of astronomers that includes Penn State scientists has discovered the first Earth-size planet orbiting a star in the "habitable zone" -- the distance from a star where liquid water might pool on the surface of an orbiting planet. (2014-04-18)

Saturn's rings reveal how to make a moon
Writing in the journal Icarus this week, Professor Carl Murray from Queen Mary's Astronomy Unit reports that recently discovered disturbances at the very edge of Saturn's outer bright A ring result from a small icy object that formed within the ring and which may be in the process of migrating out of it.

Odd Tilts Could Make More Worlds Habitable
Pivoting planets that lean one way and then change orientation within a short geological time period might be surprisingly habitable, according to new modeling by NASA and university scientists affiliated with the NASA Astrobiology Institute. (2014-04-16)

Georgia Tech researchers use XSEDE supercomputers to understand and predict how black holes swallow stars
Somewhere in the cosmos an ordinary galaxy spins, seemingly at slumber. Then all of a sudden, WHAM! A flash of light explodes from the galaxy's center. A star orbiting too close to the event horizon of the galaxy's central supermassive black hole is torn apart by the force of gravity, heating up its gas and sending out a beacon to the far reaches of the universe.

NASA's Hubble Extends Stellar Tape Measure 10 Times Farther Into Space
Using NASA's Hubble Space Telescope, astronomers now can precisely measure the distance of stars up to 10,000 light-years away -- 10 times farther than previously possible. (2014-04-14)

Chance meeting creates celestial diamond ring
Most stars with masses similar to that of our Sun will end their lives as white dwarfs - small, very dense, and hot bodies that slowly cool down over billions of years. (2014-04-09)

Scientists solve riddle of celestial archaeology
A decades old space mystery has been solved by an international team of astronomers led by Professor Martin Barstow of the University of Leicester and President-elect of the Royal Astronomical Society. (2014-03-26)
