Researchers have devised a way to measure the internal properties of stars, a method that offers more accurate assessments of their orbiting planets.  The astronomers examined HD 52265, a star…

A computer model estimate says it might be easier than previously thought for a planet to overheat into the scorchingly uninhabitable "runaway greenhouse" stage. That may mean some planets…

Exoplanets - planets around stars other than the sun - were discovered almost 20 years ago,but for the first time, X-ray observations have detected an exoplanet passing in front of its parent star.…

Astronomers have long assumed a kind of cosmic equilibrium: when a galaxy produces too many stars too quickly, it greatly reduces its capacity for producing stars in the future. A group of…

A team of astrophysicists using results based upon observations of 10 quasars say they have discovered the extent to which quasars and their black holes can influence their galaxies.  The…

A new study by astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) telescope have discovered columns of cold, dense gas exiting the disk of nearby starburst galaxy NGC 253…

It would be great to study Mars "on location". You could do as much in a day or two, as our rovers could do in years. But there's a conundrum to face. Humans are host to hundreds of trillions of…

There are valley networks branching across the Martian surface, which makes it reasonable to believe that water once flowed on the Red Planet. Where water might have come from would be another…

On July 18th, 2013, at 9:06 a.m. EDT, the Solar and Heliospheric Observatory (SOHO) captured an image of a gigantic coronal hole hovering over the sun's north pole. Coronal holes are dark, low…

The orbital motion of two distinct populations of stars in an ancient globular star cluster, 47 Tucanae, have offered proof they formed at different times and it provides a rare look back into the…
