Jupiter’s moon Europa is on the shortlist of places we might discover alien life in our solar system. And today, the prospects for finding extraterrestrial microbes on this little ice moon got a lot better, when NASA unveiled new evidence for water geysers near Europa’s south pole. The discovery strengthens the case…
SpaceX has been talking up its Martian travel plans for a while now, but we still don’t know how it intends to get (or survive) there. As of today, however, it’s cleared a major hurdle: the rocket engine it will use to get to the Red Planet just fired-up for the first time.
In recent months, there’s been growing evidence that Pluto is hiding a liquid water ocean beneath its frozen surface. New models by researchers at Brown University support this hypothesis, and take it one mind-boggling step further: Pluto’s ocean may be more than 100 kilometers (62 miles) deep.
Earlier this month, we watched a SpaceX rocket—fully loaded with its satellite—explode suddenly and inexplicably. At the time, the cause remained a mystery, but now SpaceX’s engineers have traced the flaw to its source.
Last summer, something strange happened on Rosetta’s comet. After a period of calm, the comet began erupting, throwing huge jets of comet dust into space before abruptly stopping. Now, we finally know what happened.
Hubble’s deep field images have provided the farthest glimpses we’ve ever had of galaxies in spaces. Combining those images with a new telescope view has revealed that there are even more galaxies there than we knew—including a mysterious, new type of galaxy.
In just seven days, the Rosetta spacecraft will smash into Comet 67P. A new visualization shows how it’ll go down.
Tilt-shift lenses can make whole cities look like desktop miniatures through some amazing optical trickery. Unfortunately, we don’t have any of them up in space, but it hasn’t stopped some cosmic creatives from trying to mimic the effect on photos taken by NASA, ESO, and other space research groups.
It’s a happy day when astronomers figure out what’s up with an enormous space blob—and the answer doesn’t imply the immediate destruction of humanity.
Almost as soon as Pluto came into view, we saw it: A big heart splashed across half the dwarf planet’s surface, like something left it there on purpose for us to see. A year after we spotted it, we have an answer as to what put it there.
Something very strange is going on around Pluto. The icy world that sits some 3.6 billion miles from the sun appears to be emitting x-rays—high energy radiation associated with gases with temperatures of a million degrees. That makes Pluto the furthest known x-ray source in our solar system. If confirmed, the finding…
Look up—but make sure you do it quickly. The world’s fastest rocket, United Launch Alliance’s Atlas V, is launching into space this afternoon, and you can watch it happen at 2:30pm EDT.
The winners of the annual Insight Astronomy Photographer of the Year have been announced. From eerie eclipses through to battered lunar landscapes, these images are an absolute treat.
Astronomers working with the Hubble Space Telescope have captured unprecedented images of a comet in the process of disintegration. It’s our clearest view yet of this celestial phenomenon in action.
Almost as soon as Pluto’s moon Charon came into view, we had a question: what’s that big red splotch on top of it? Now, we finally have an answer.
Two weeks ago, a SpaceX rocket inexplicably burst into flames, taking its satellite payload up in smoke. Now the space company has given a date for when we can expect to see its rockets back in the air.
Some may call it excessive, unreasonable, exhibitionist. What kind of masochist wants to stare at a billion pinpricks of light all at once, anyway? Why, the scientifically inclined one, of course. The astronomer who’s hellbent on picking apart the universe and reducing your life to a clump of dust needs absurdly…
In two weeks, the European Space Agency will crash-land its prized Rosetta spacecraft, marking a dramatic end to the whirlwind two-year science mission that saw humanity’s first-ever comet landing. It’ll be 48 action-packed hours as Rosetta descends to its ultimate resting place on Comet 67P—and to get you properly…
As is by now traditional, a studio has bought the rights to a book that hasn’t even come out yet. In this case, it’s Sony Pictures making a movie out of astronaut Scott Kelly’s Endurance: My Year in Space and Our Journey to Mars.
