55 Cancri e was first identified back in 2004, but at the time scientists thought that it was covered in water and rocks, much like the Earth. We now know that's probably not true and, what's more, the most interesting find regarding 55 Cancri e could be under the surface.
Designing and building a new space telescope takes such a long time that even before Hubble 2.0 (the James Webb Space Telescope) has launched, astronomers are already working on Hubble 3.0, known right now as ATLAST.
Felix Baumgartner had a pretty good weekend. Baumgartner shattered a few world records and popped a huge bubble of anticipation as he leapt from the stratosphere and rocketed past the sound barrier, reaching Mach 1.2 (833 mph) as he hurtled towards the ground. Happily, he didn't shatter himself.
Space. It's big, and it's deep, but as far as we humans here on Earth are concerned, it may as well be a perfectly flat picture painted up there across the sky. It's hard to get much in the way of depth through a telescope, but with a little bit of creativity and artistic license, it's possible to 3D-ify some truly beautiful nebulae.
Felix Baumgartner's attempt to set a record-breaking high-altitude jump from 23 miles above Earth was delayed on Monday, but should happen sometime later today. Here's what you can expect.
One billion years is a span of time that's almost impossible for humans to conceive of: our civilization is only a few thousand years old, and we'll be lucky if we see another few thousand into the future. With that in mind, a team of artists is sending a special time capsule into space, where it should last until the sun eats it.
Astronomers have found something more interesting at the center of our Milky Way galaxy than just a black hole: a star orbiting that black hole at the record-breaking speed of 3,100 miles per second. It takes less than twelve years to make one full orbit, but its speed isn't its only scientifically interesting aspect.
The search for extraterrestrial life continues. For three Penn State researchers, the search should not focus on radio waves, as it long has, but on Dyson Spheres....
Mars may be the first planet in the solar system to have a robot for mayor. (Something that was already predicted by Reddit.) NASA's Curiosity rover just checked-in on Foursquare on Mars and, unless Opportunity gets its act in gear, could continue to check-in unopposed and win the coveted spot of mayor.
Back in January of 2010, the Kepler Space Telescope was checking out a four-planet system called KOI-94, when it noticed something weird. Additional observations and recent analysis suggest that what Kepler saw was a double exoplanet transit, and since nobody's ever seen this before, astronomers have had to invent a brand new term to describe it: behold, an exosyzygy.
