A new study has revealed the source of an unusual ring of radiation that developed last September, encircling the Earth for a month before disappearing as mysteriously as it appeared.
A resupply mission headed toward the International Space Station was delayed early Sunday morning due to a technical glitch.
British researchers have found alien life arriving on earth from space.
The discovery of enormous arms of hot gas located in the Coma cluster of galaxies reveals new insight into how the cluster has formed over the years, growing through the merger of smaller groups and clusters of galaxies before becoming one of the largest structures in the universe held together by gravity.
Extensive testing by NASA's Curiosity rover has revealed that, contrary to previous research carried out by US and international scientists, Mars's environment contains no methane. The finding is considered a major blow to the possibility of life on the Red Planet due to the fact that the gas, produced during digestion, often signals the presence of living organisms.
Europa, the icy moon orbiting Jupiter, likely revolved around a tilted axis at some point, according to NASA scientist who analyzed the moon's distinctive ice cracks.
Space tech company Orbital Sciences has successfully launched its cargo capsule destined for the International Space Station.
We have about 1.75 billion years to find another planet that can sustain life.
The European Space Observatory's VLT Survey Telescope has captured the sharpest image ever obtained of the Prawn Nebula, a huge mass of gas and cosmic dust about 6,000 light years away from Earth.
Mars's Aram Chaos, the uneven surface of an ancient impact crater, was formed when an underlying lake of ice melted, a new study suggests.
Researchers at the European Space Agency (ESA) have developed a robotic prototype that could serve as the basis for future robots designed to explore foreign space bodies.
Orbital Science managers and NASA officials gave the green light for Wednesday's launch of the private company's Cygnus spacecraft which is set to perform a demonstration resupply mission to the International Space Station.
NASA's Hubble Space Telescope has discovered a population of an estimated 160,000 globular star clusters -- the largest such grouping ever discovered.
MIT researchers have found that space weather, specifically high-energy electrons in space, may be responsible for recent satellite glitches.
For the first time, scientists have observed a jet of high-energy particles emanating from a dying star, providing crucial insight into the formation of the symmetric clouds of gas known as planetary nebulae.
