Astronauts aboard the International Space Station are preparing for possible spacewalks this week to repair the outpost's failed cooling system, NASA said on Sunday.
China landed an unmanned spacecraft on the moon on Saturday, state media reported, in the first such "soft-landing" since 1976, joining the United States and the former Soviet Union in managing to accomplish such a feat.
Fast radio bursts, which are cosmic chirps that last for only a thousandth of a second, continue to defy explanation. While the characteristics of these radio bursts suggest that they come from galaxies billions of light-years away, scientists have recently uncovered a new origin. It turns out that ...
NASA will turn over one of its mothballed space-shuttle launch pads to privately owned Space Exploration Technologies, or SpaceX, which intends to set up a second site in Florida for its Falcon rockets, officials said on Friday.
ESA's billion-star surveyor Gaia, less than a week from launch, is now tucked up inside the fairing that will protect it during the first few minutes of ascent into space.
It turns out that Earth isn't the only place where you can find a molecule containing a noble gas. Using an instrument aboard Europe's Herschel Space Observatory, researchers have discovered a noble gas, argon hydride, in the Crab Nebula.
Determining the age of rocks is an important part of finding out more about a planet. That's why researchers have determined ages of rocks from planetary bodies in the past. Yet these experiments have always been conducted on Earth. Now, researchers have successfully determined the age of a Martian ...
It's the end of the universe as we know it--sort of. Physicists have long predicted that the universe may one day collapse and that everything within it will be compressed into a small, hard ball. Now, new calculations confirm this prediction and shows that the risk of collapse is actually greater t...
NASA is assessing a problem with one of two cooling systems aboard the International Space Station, a potentially serious but not life-threatening situation, officials said on Wednesday.
NASA's Hubble Space Telescope has made some surprising discoveries when it comes to Jupiter's moon, Europa. It's spotted water vapor above the moon's frigid south polar region, providing the first strong evidence of water plumes erupting off the moon's surface.
Atmospheric peculiarities similar to Earth and a few other planets may also be common to billion other planets and moons in the galaxy, researchers find.
