A star in the Ursa Major constellation, about 15.6 light years away from Earth, gave astronomers a surprise when it unleashed a flare so intense the star to become 15 times brighter in a matter of minutes.
Russia's Valentina Tereshkova was the first woman to reach space 50 years ago, shouting "Take off your hat, sky, I'm coming!" as she blasted off and into orbit.
Tucked far away in the recesses of a highly elliptical orbit around the neighboring star TW Hydrae may be a planet.
Astronauts and cosmonauts residing in the International Space Station have long relied on the “anti-gravity” treadmill, called the “Treadmill Vibration Isolation System,” (TVIS), as a way to counteract the debilitating effects of a lack of gravity, including a loss of muscle mass and bone density. So when collectSPACE.com incorrectly reported that the high-tech device had been jettisoned as space junk, it created a stir.
Temperatures in the Martian atmosphere regularly rise and fall not just once but twice a day.
“Earth is calling. Be one of the first.”
NASA astronomers observed more than two dozen potential black holes in the nearby Andromeda Galaxy, a discovery the space agency called "unprecedented."
NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR) has caught a glimpse of a black hole napping almost a decade after it was observed snacking on gas.
Astronomers have discovered a new type of variable star based on the detection of extremely small changes in the brightness of stars located in the cluster NGC 3766.
NASA researchers identified what appear to be hunks of frozen carbon dioxide, also known as dry ice, gliding down Martian sand dunes on cushions of gas similar to miniature hovercraft, leaving furrows as they go.
Boron, believed to have played a key role in the formation of RNA and thus the development of life, was identified in a Martian meteorite by researchers from the University of Hawaii at Manoa NASA Astrobiology Institute.
Scientists have measured the least massive galaxy ever found, according to a study published in The Astrophysical Journal.
From a distance, Saturn’s moon Dione may look something like the Earth’s satellite: gray and static. New close up images taken by NASA’s Cassini spacecraft, however, suggest that it may have been active in the past and could still be now.
China’s Shenzhou-10 (Divine Craft) spacecraft blasted off Tuesday morning from the Gobi desert with three astronauts on board for a 15-day mission representing the latest step toward the development of the nation’s own space station.
