A team of scientists say they have detected and measured an excess of positrons in the cosmic ray flux, marking what is likely the first observation of dark matter.
Space scientists from the University of California have used a computer model to determine that our galaxy may contain anywhere from 70 to 2,000 black holes existing along its outer edges.
NASA's Mars rover Curiosity may have identified perchlorate in a sand patch within the Gale Crater. Perchlorates are a known energy source for some types of Earth-dwelling microbes.
Thanks to a little help from some friends, a NASA announcement highlighting the agency's space exploration efforts will be shown before the next "Star Trek" move in some theaters across the U.S. in May.
As scientists watched as a black hole 47 million miles away consume a object, they were watching a preview of an event coming to our own neighborhood when the black hole at the center of the Universe is scheduled to consume a passing gas cloud later this year.
After years of debate, scientists believe they may have discovered how spiral galaxies grew their arms.
Last month NASA researchers flew an unmanned aerial vehicle (UAV) equipped with cameras and sensors into the sulfuric plume and over the summit crater of Turrialba Volcano
NASA's Curiosity rover has basically stayed in one spot for more than two months, traveled less than a 10th of the way to its primary goal and has used nearly a third of the mission's allotted two year timeframe, which is putting pressure on the mission team back on Earth to get the rover rolling.
Thirty-five green rocks found in Morocco last year may actually be the first known meteorite samples from Mercury the wold has ever seen.
NASA's 2014 fiscal budget request includes $100 million in funding help to send a spacecraft to capture a small asteroid and return it to man, according to Aviation Week.
Astronomers at NASA have gathered data on what may be one of the most spectacular comets stargazers have seen in decades thanks to observations from the space agency's Swift satellite.
The odds that a comet will hit Mars in October 2014 are 1/2000, slim, but more likely than winning the lottery.
Three men prepare to take off in what will be the fastest journey to the International Space Station yet.
The rings around Saturn are bodies that have been around for more than 4 billion years, from a time when the solar system was in its infancy, according to NASA. The recent coloring on the rings' surface is due to recent "pollution" from a rain of meteoroids from beyond the solar system.
