Since 2005 BC over 35,000 meteorites are known to have hit the Earth — but just 1,107 have actually been seen falling. This visualisation shows how they pockmarked our planet over time. Read More >>

Take a deep breath. You're lucky to be able to. Without a handy blanket of atmosphere gases to swaddle us all, we'd be no more than a twinkle in evolution's eye. But that wonderful blanket of gas is slowly escaping, molecule by molecule, and there's not much we can do about it. Read More >>

A massive explosion, equivalent to five tonnes of TNT annihilating our satellite's surface, hit the poor Moon back in March. It created a bright flash that glowed like a 4th magnitude star, and could be seen by the naked eye, but apparently no one spotted it, until now. Read More >>

After being strapped onto the front of a 15-story controlled explosion and launched clear out of the atmosphere to live in an experimental laboratory orbiting around the Earth at thousands of miles an hour, the least NASA can do is give you a good meal. Read More >>

45 mice, 15 newts, eight gerbils and a handful of snails returned to Earth today after a month in space in a Russian capsule. The Bion-M completed a parachute-assisted landing about 750 miles southeast of Moscow, and researchers immediately set up a mobile lab near the capsule to begin tests on the animals. Read More >>

If you want a Curiosity rover of your own but don't quite have NASA's budget, you can save yourself £2,499,999,850 by going with designer Arnold Patrick Martin's beautiful wooden model. It doesn't move, the cameras don't work, and it probably won't survive a trip to Mars, but it's also only £100. Read More >>

Arguably the most iconic skyline in the world (thanks to movies) would look completely different if it was on another world. On Venus, New York City would be a yellow haze, on Mercury would look glow in the dark, on Mars would make everything rusty and on Uranus and Neptune would totally obliterate the city. Read More >>

Catching a glimpse of even regular neutrinos—low-energy particles generated in the atmosphere—is difficult enough, but spotting a "cosmic neutrino" left over from the Big Bang has been downright impossible. That is until this cubic kilometer buried under Antartica's frozen wastes started looking. Read More >>

It was a simple 31-second clip, uploaded to YouTube in early January—a watch flopping weightlessly around its owner’s wrist, the first such video from Commander Chris Hadfield aboard the International Space Station. No explanation, no context, just metal links and a watch face swishing around a hairy Canadian arm like a tangled length of seaweed. This, and the dozens like it that would follow, is how Chris Hadfield, who returns to Earth today, became the most important astronaut in decades. Read More >>

Commander Chris Hadfield's cover version of Space Oddity took the internet by storm yesterday, but it got a lot of people thinking: does it amount to the most expensive music video ever made? Read More >>

After inspiring all of us on Earth, Commander Chris Hadfield and crew have finally re-joined us here. The Soyuz space capsule landed safely at 10:31 PM EDT in Kazakhstan. Hadfield had spent 144 days on the ISS, 2,336 orbits around the planet and totaled up around 62 million miles. That's a lot of miles! Read More >>

Astronauts are usually pretty busy while they're off planet so there hasn't been a lot of time to, um, look into this stuff, but it's unclear whether humans can procreate in weightless conditions. Apparently, you can't just march into space like you own it and do whatever you want. Read More >>

That ammonia leak on the ISS just had to be fixed, and while NASA's got robot slaves in space to do some of its bidding, there are a few things real men still have to do. Fixing stuff like leaks is one of them. Two astronauts had to do an impromptu EVA, fit a new pump, and dive back in. This is what it looked like. Read More >>

ISS Commander and mustachioed Canadian Chris Hadfield has given us no end of joys during his current five-month stint floating above our blue orb. But perhaps none of them is as touching — and just downright incredible — as his sendoff cover of David Bowie's Space Oddity. Read More >>

It's going to take more than a Swiffer to deal with this situation. Researchers and public health experts at the Humans 2 Mars Summit (H2M) grappled with the question of how to deal with Martian dust if a manned mission to Mars could actually get off the ground by 2030. Read More >>
