To combat the increasingly dense layer of dead satellites and miscellaneous space debris that are enshrouding our planet, no idea -- nets, lassos, even ballistic gas clouds -- seems too far-fetched to avoid. Now, an international team of researchers led by Japan's Riken research institute has put ...

Space telescopes are great, but they're hardly the cheapest things to build, launch and maintain, which means scientists are forced to make compromises. The solution to this problem isn't to build a better rocket with a bigger carrying capacity, but to rely upon a low tech way to make any party fa...

The Dawn spacecraft has recently captured the sharpest pictures of Ceres to date, showing the dwarf planet's bright, sunlit north pole. NASA's space probe has been steadily making its way to the celestial body since 2012 after a 14-month stint orbiting the asteroid Vesta. It fired up its ion thrus...

The Philae comet lander might be slumbering, but it can still teach you a thing or two about the nature of celestial bodies. European Space Agency researchers have compared Philae's data against the more distant Rosetta probe, and they've discovered that Comet 67P/Churyumov-Gerasimenko isn't magne...

We've finally gotten our first glimpse at the mysterious material that supposedly makes up 27 percent of the universe. It's only taken two years of research, the efforts of 300 researchers working for the Dark Energy Survey (DES) and a 570-megapixel camera attached to the Victor Blanco telescope i...

Don't look now, but what you know about the universe's growth might have been turned on its ear. University of Arizona scientists have learned that a certain type of supernova (Ia) isn't the reliable measuring stick for universe expansion that previous data would suggest. By comparing optical and ...

Looks like NASA's Chief Scientist Ellen Stofan may have over-estimated how long it would take to find extraterrestrial organisms. For the first time in the history of astronomy, scientists have discovered two complex organic molecules, which is vital to the formation of life as we know it, outside...

The quest to find proof of life beyond Earth hasn't been without its setbacks, but NASA isn't deterred. If anything, it's optimistic -- Chief Scientist Ellen Stofan now claims that there will be "definitive evidence" of extraterrestrial life within the next 10 to 20 years. Given the sheer number o...

For its crazy 2020 asteroid capture mission and other projects, NASA is developing next-gen "Hall effect thrusters" to corral an asteroid and put it into the moon's orbit. At the same time, the European Space Agency (ESA) is trying to improve its own Hall thrusters to power future missions. If you...

Russia's Roscosmos space agency is in a bind. It makes money ferrying American astronauts to the International Space Station, but it's going to have a lot of unclaimed seats once NASA starts using capsules from Boeing and SpaceX. The solution? It's resuming space tourism. When 2018 rolls around, E...
