On Thursday, astronauts aboard the International Space Station noticed odd flakes floating about outside, which turned out to be ammonia leaking out of the radiator lines of the space station's power system. Now, after a day of deliberation, it turns out two astronauts will leave the ISS, and brave the great abyss to try to fix the problem. Uh oh. Read More >>

In case you missed it last night, Virgin Galactic successfully performed its first rocket-powered test flight of the SpaceShipTwo. In other words, space tourism is nigh, and this is what it looks like. Read More >>

Ever feel like you're all alone in this big, ol' universe? Well, cheer up, because NASA has just discovered two prime planet candidates that fulfill practically every necessary condition we're aware of to house life. And according to William Borucki, chief scientist for NASA's Kepler telescope, these two are the best bets we've found yet. Read More >>

Human space travel comes with a host of problems, not the least of which is our general inability to survive in a vacuum without, you know, dying. But a new technique that's done wonders for fruit fly larvae and could one day lead to the same for humans may have solved that problem. By bombarding larvae with electrons (as seen in the above video), Scientists discovered that they could get by in a vacuum totally unscathed. Read More >>

Astronauts' stays on the International Space Station generally last for around 6 months or more, so it makes sense that they'd start getting hit with a little nostalgia for the motherland they're so casually encircling. How nostalgic, you ask? Very: 1,129,177 photos worth, to be exact. Rocket scientist Nathan Bergey had the ingenious idea to turn these ISS snapshots into the ultimate space scrapbook—by plotting the coordinates of every single image taken from space. Read More >>

Yesterday, while most of us were busy going about our day, everyone's favourite flaming ball of plasma decided to give NASA's cameras a little show. More specifically, the Solar Dynamics Observatory managed to capture our Sun's biggest solar flare of the year thus far. Read More >>

Now that nuclear-thermal rockets are becoming a reality, we may very well be shipping off the first human pioneers to Mars (both safely and efficiently) in the not-too-distant future. This, of course, leaves the question of exactly who will become the first generation of Martian-Earthlings. Read More >>

There's been no shortage of Mars pictures since Curiosity landed. We've got Martian mountains, rover selfies, the works. But thanks to a little image stitching by a clever dude back here on Earth, now we have Mars Street View, kind of. Read More >>

We've known for ages that the universe is 13 and a quarter billion-ish years old, but now a recent study is tweaking that number just slightly. Findings by the European Space Agency's Planck space probe show that the universe is about 80 million years older than previously thought, bringing the total to 13.81 billion. Read More >>

Ever since July 16, 1969, the rockets that pushed Apollo 11 out of the atmosphere, taking mankind to the moon, have lain at the bottom of the Atlantic ocean. Jeff Bezos has been keen to get them back, and now, thanks to his hard work and vast fortune of book money, they're seeing the light of day for the first time in decades. Read More >>

For the very first time, a man-made object has reached the cosmic abyss beyond the farthest reaches of our solar system. As of today, Voyager 1 is the first spacecraft to begin the endless journey into deep space. Read More >>

In a new study that's sure to make everyone's world just a little darker, scientists have discovered that sex in space could lead to severe health problems and life-threatening illnesses—brain disease and cancer included. Read More >>

The photo you see above was taken on February 28th when the Virgin Galactic and Scaled Composites team tested, for the first time, the rocket that will power its first test flight before going into orbit. And it was a raging success. Read More >>

NASA's Hubble Telescope peered deep into a cluster of galaxies called Abell 68 recently, and found a wicked space invader that looks like it's headed right for us. Brace for impact! Read More >>
