It's no longer rare to hear reports of solar flares that could affect Earth, but seeing them in vivid detail? That's another matter. Thankfully, NASA's Solar Dynamics Observatory recently captured a high-intensity X1.8 flare (80 percent more intense than an already huge X1 flare) in action. The pr...

It's official: you can "upload" tools to space. Following its earlier test run, the International Space Station has used 3D printing to make a ratchet based on instructions sent from Earth. It's not exactly a sophisticated implement, but it underscores the advantages of letting astronauts print t...

Dark matter remains one of the most mysterious elements of the universe, because it's completely invisible to us. It neither emits nor absorbs light, so we can't observe it directly -- not even if we use our most powerful telescope. A team of researchers believe that they've come across important ...

NASA's Orion capsule has blasted off on the farthest journey into space anyone has ever attempted since the last Apollo moon mission. In fact, a Delta IV rocket will propel it to an altitude of 3,600 miles, roughly 14 times that of the International Space Station's -- and for good reason. NASA and...

NASA's launch clock is finally moving into the digital age. The new countdown timer sports a 1280 x 360 resolution screen (which NASA admits is far from being HD) and measures in at 26 feet wide and some 7 feet tall. The $280,000 unit is a bit more capable than its predecessor (pictured above, che...

According to The Wall Street Journal, EU ministers are finally about to approve plans for a more affordable version of the Ariane series -- the same family that launched Rosetta back in 2004. What counts as affordable when developing a rocket, is reported...
