For 16 years NASA’s Rossi X-ray Timing Explorer, RXTE to his friends, provided unprecedented views into the hearts of black holes, white dwarfs and neutron stars. Having far surpassed its initial goals, RXTE has sent its last transmission back to Earth and has been switched off for good.
Have you ever wondered why there are so many amazing videos of Earth from orbit nowadays? The answer is simple: the amazing low-light performance of current DSLR cameras, like the Nikon D3 used by Expedition 29 Commander Mike Fossum.
When the Commander of the International Space Station says he just saw "the most amazing thing I have ever seen in space," you know you're in for something incredible. We've never seen a view of a comet like this.
NASA's new VIIRS—or Visible Infrared Imager Radiometer Suite—satellite travels in a sun-synchronous orbit. So as it photographs the planet, each photo is taken at the same time ensuring that all the images have similar lighting.
I find this funny and sad at the same time: someone at NASA had to write an article explaining the obvious to the usual morons — the doomsaying clowns claiming that the world will end in 2012 because of a nearby supernova.
Rejoice, for comet Lovejoy has survived its close encounter with the Sun! NASA's Solar Dynamics Observatory has captured the exact moment it went close in behind the Sun, then out again on the other side, surprisingly more or less intact.
NASA is readying a new kind of space device: a harpoon designed to rapidly fire against comets, easily taking chunks of its surface with surgical precision. It's now being tested by scientists at the Goddard Space Flight Center.
This is Puppis A, the remnants of a violent supernova that exploded 3,700 years ago, glowing red as its shockwaves still heat up the dust around it. But Puppis A is really special because it hides the "Cosmic Cannonball."
I'm surprised that, after three decades of amazing launches, hundreds of outstanding missions, great science and some very sad moments, there's not more stuff celebrating the space shuttle. Thankfully, NASA is coming to the rescue with this free iPad app.
The possibility of alien life has captivated our imaginations for generations. Now that possibility just got a big boost as Kepler's managed to find and confirm a potentially Earth-like planet. It's just 600 light years away and occupies that magic 'habitable zone' around its star, like the Earth does around the sun.
