Crew members aboard the International Space Station will now have added space to their home in Earth’s orbit. NASA on Saturday announced it had the Bigelow Expandable Activity Module (BEAM), which will be analyzed over the course of a two-year test period. The module is part of an experimental line of “expandables,”which are lightweight and require minimal payload volume on a rocket, but expand to potentially provide new and comfortable space for astronauts to live and work.

When the full moon shines in the night sky, it's easy to see the varied landscapes and vast craters on its surface. But not every crater on the moon is visible to the naked eye; there are some parts we never see at all. Now, a team of researchers has used UV light to see the "dark" side of the moon, and they found something rather surprising. The moon has two craters that are much newer that astronomers expected, the...

University of British Columbia astronomy student Michelle Kunimoto has added four new planets to the map of the sky, including a system that might be an abode for life. (Martin Dee/UBC) Not every recent college graduate can boast a resumé quite like Michelle Kunimoto's. The 22-year-old, who studied astronomy at the University of British Columbia (UBC), made the ultimate stargazing discovery: she spotted four previously unknown exoplanets. "I got ," Kunimoto told Metro. "The whole theme of Star Trek, curiosity...

Amateur astronomer Chris Schur captured the shot of a lifetime when he documented the comet 252P/LINEAR in all its turquoise glory on the morning of April 2. Seen in the gallery above, the image was after the comet made its close pass of Earth back in early April. Using an astrograph set at a 39-minute exposure, Schur got the amazing image of the comet surrounded by brilliant stars. "I was just able to glimpse this object [with the] naked eye,...

Meteorologist Ari Sarsalari takes a look at a beautiful picture of a storm cloud taken from the International Space Station. ...

Thunderstorms are fascinating to observe from the ground, but seeing one from outer space is even more spectacular. The image below, which shows the anvil of a thunderstorm, was on Tuesday. Peakeis a flight engineer for the European Space Agency, and he snapped this stunning photo on May 28from the International Space Station (ISS), where he has. The anvil is the flat top of a cumulonimbus (thunderstorm) cloud, which stands out remarkably in this photo. Pictured here is the anvil...

The Rosetta Spacecraft took an intimate Valentine's Day photo series of Comet 67P. (ESA/Rosetta/NavCam) Comets may often experience repeated cycles of destruction and reformation, spinning fast enough to break up but then reforming as their separate pieces slowly coalesce over time, a new study finds. This finding could help explain the odd shapes of many comets imaged so far, researchers say. Comets are clumps of ice and rock that generate long tails as their orbits bring them near the sun....

Arizona stargazers were baffled Thursday morningby a mysteriousbright flash that lit up the night sky. Shocked residents uploaded video of the fireball to social media and hundreds of tweets buzzed with speculation over the origin of the unidentified space object. A mysterious, bright flash of light was seen over Arizona on Thursday. (Ian Schlueter) Additionally, some locals heard a loud boom and even reported feeling the ground shake, , though the Arizona Geological Survey didn't pick up any readings of...

Just when scientists thought they had an understanding of the inner workings of the cosmos, it throws them for another loop. A team of astronomers have calculated that , according to therelease from NASA. If their new findings are correct, then science’s basic understanding of what’s been going on in the universe for the past 13.8 billion years could be inaccurate. Their findings were released in a study Thursday. "This surprising finding may be an important clue to understanding those...
