We're learning more about the comet that a European Space Agency paired up with its Rosetta probe last fall. For one thing, it has "goosebumps" on steep cliff faces. It's also highly porous.
Scientists call them "fast radio bursts," or FRBs: mysterious pulses of radio waves coming from far, far away. Researchers in Australia say they've observed one in real time.
The company's resupply mission to the International Space Station went off without a hitch last week, but an attempt to land the spent booster on a floating platform didn't go as well.
The Beagle 2 Mars lander was lost in December 2003. Today, scientists confirmed their spacecraft was found partially deployed on the surface of the Red Planet.
The International Dark-Sky Association has named only three "gold-tier reserves" on Earth where a "full array of visible sky phenomena can be viewed." There's only one in the Northern Hemisphere — at the the Kerry International Dark Sky Reserve in far Southwestern Ireland.
An experimental rocket launched by SpaceX Saturday was a partial success. A cargo capsule will reach the International Space Station, but the spent rocket failed to land on a barge in the Atlantic.
The space firm will send a supply capsule into orbit, and then try a new way to recover the part of the rocket that carried it. If it works, the cost of going to space could be reduced dramatically.
The Mars rover Opportunity is getting on in years. It has been on Mars' surface for over a decade, and now it's having memory problems. NASA has come up with a plan to fix it.
