The Herschel Space Observatory was the world's largest and most powerful infrared telescope, able to see parts of the universe nothing else could. Unfortunately, it met its maker this week when it ran out of the liquid helium coolant it requires to map hidden corners of the cosmos. Read More >>
Over 47 million light years away, in a galaxy called NGC 4845, there's one hungry black hole. In fact, scientists have watched in awe as, soon after it stirred from dormancy, it chomped away at a planet 30 times the mass of Jupiter. Read More >>
NASA and the ESA have teamed up to measure how fast a black hole, that weighs 2 million times more than our Sun, spins — and the result's mind boggling. Read More >>

"Yes, that's why you can't escape the event horizon - the necessary velocity to escape would exceed the speed of light.
Looking back, I'm not sure..." More »
Following last week's meteorite explosion, scientists have finally had chance to sit down and figure out exactly what happened — and the results help explain why it shook Russia so hard. Read More >>
This amazing image shows 90 per cent of Mars's surface, imaged in ultra-high detail by the stereo camera aboard the European Space Agency's Mars Express. Read More >>
Our solar system is positioned near the center of the Milky Way, not far from the galactic core. It's a nice part of town, sure, but it doesn't allow for a very clear view of the rest of the galaxy. That's prevented us from studying many of the Milky Way's fundamental aspects, like whether it has two arms or four, how big it is, how fast it's moving, and whether we're someday going to ram headfirst into the Andromeda galaxy.

This image, acquired by France's Pleiades satellite, makes Dubai look like a well lit diorama table. Given its absurd skyscrapers, ridiculous fountains and insanely sculpted town planning, perhaps that should come as no surprise. [ESA] Read More >>

Europe will receive nearly infallible weather data thanks to this trio of school bus-sized spacecraft, and the EU saves £4.5 billion in weather-related damage annually. This is what the atmosphere will look like in HD. Read More >>

With over one million observations since it launch on April 24, 1990, the Hubble Space Telescope has been a endless source for insane wonders, unprecedented scenes and humbling experiences. However, many of its most amazing images have never been seen before by anyone—until now. In fact, some images actually show objects that nobody knew existed before. Read More >>
On Friday, history was made as SpaceX's Dragon docked with the International Space Station, marking the start of a future of privatised space exploration. Now, one of the astronauts aboard the ISS has shared his reactions to Dragon and posted them on his blog. Read More >>
You are looking at the largest piece of tin foil in the planet, one of the James Webb Space Telescope's sunshield membranes. There will be five of these membranes, which will keep its core at 50 Kelvin (-369.67F or -223.15C). Read More >>
The European Space Agency's next mission will be known as JUICE -- Jupiter Icy moons Explorer -- an attempt to see what lies on and around the alien worlds of Europa, Ganymede and Callisto. Read More >>

The frozen crust of Enceladus, Saturn's sixth largest moon, may be hiding subsurface water and maybe even life. But scientists will first have to bore through the tundra to see what lies beneath and they may rely on the IceMole to do the digging. Read More >>
The European Space Agency' Mars Express spacecraft has discovered "large volumes of water ice" hiding only 65 feet underground the red planet's surface, in the Phlegra Montes mountain range. I could be used by future human explorers. Read More >>

"That there's water on Mars is pretty insignificant! What's actually more crucial is figuring out how to survive outside of Earth's gravitational field..." More »
Sitting dead in Earth's orbit thanks to a premature engine shutoff, Russia's Mars-digging probe has been giving ground controllers the cold shoulder for 14 days. An ESA tracking station in Australia has now, finally, managed to make contact. Read More >>
