A popular theory holds that ocean water was brought to Earth by the ancient impacts of comets and asteroids. However, new data from the European Space Agency’s Rosetta spacecraft indicate that terrestrial water did not come from comets like 67P/Churyumov-Gerasimenko.

After a voyage of nearly nine years and three billion miles —the farthest any space mission has ever traveled to reach its primary target – NASA’s New Horizons spacecraft came out of hibernation on Dec. 6th for its long-awaited 2015 encounter with the Pluto system.

Findings from a NASA rocket are redefining what scientists think of as galaxies. Galaxies may not have a set boundary of stars, but instead stretch out to great distances, forming a vast, interconnected sea of stars.
NASA's Lunar Reconnaissance Orbiter has found strong evidence of geologically young volcanic activity on the moon. Some deposits appear to be less than 100 million years old, corresponding to Earth's Cretaceous period, the heyday of dinosaurs.
NASA's MAVEN spacecraft has reached Mars and it is beaming back "First Light" images of the Red Planet's upper atmosphere. The data could help researchers understand what transformed Mars from a hospitable planet billions of years ago into a desiccated wasteland today.
NASA spacecraft and rovers are gearing up to observe a once-in-a-lifetime comet flyby of Mars on Sunday, Oct. 19.

Mark your calendar: On Oct. 8th, the Moon will pass through the shadow of Earth for a total lunar eclipse. Sky watchers in the USA will see the Moon turn a beautiful shade of celestial red and maybe turquoise, too.
A NASA instrument onboard Europe's Rosetta spacecraft has shown that the core of Comet 67P/Churyumov-Gerasimenko is unusually dark--darker than charcoal-black--when viewed at ultraviolet wavelengths.
A mysterious X-ray signal from the Perseus cluster of galaxies, which researchers say cannot be explained by known physics, could be a key clue to the nature of Dark Matter.
NASA's New Horizons spacecraft is only a year away from Pluto. Researchers are buzzing with anticipation as NASA prepares to encounter a new world for the first time in decades.
Scientists analyzing data from NASA’s Cassini mission have found evidence of an ocean inside Saturn's largest moon, Titan, which might be as salty as the Earth's Dead Sea.
In early June, a laser beam lanced out of the night sky over California, heralding a breakthrough in space communications.
