Doomsday isn't far from many people's imaginations, whether it's the end of the Mayan calendar, the rapture, or a massive asteroid smashing into the Earth. Now, one of these far-flung scenarios may become even less likely.

The European Space Agency announced this week that it's in the beginning phases of an "Asteroid Impact and Deflection Mission" with its U.S. partner Johns Hopkins Applied Physics Laboratory. The eventual goal of the mission is to verify whether scientists can collide with an asteroid that's hurtling through space -- so as to avoid any possible … Read more

Canadian astronaut Chris Hadfield is known for playing his guitar in zero gravity on the International Space Station. To keep his fingers in playing shape, he has to keep his nails clipped. Down here on Earth, that's no problem -- you just grab some clippers and go at it. In space, it's a little more complicated.

Hadfield demonstrates his trimming method in a video released by the Canadian Space Agency. The first step is to procure a nail clipper. This is just like our Earth nail clippers, except it has Velcro on it to keep it from floating around and bumping into astronauts or machinery.… Read more

ThinkGeek boasts that the HAL 9000 life-size replica is the "most movie-accurate HAL 9000 replica ever created." Let's hope it's only movie-accurate enough to be entertaining and not deadly.

If you're a fan of HAL 9000 and want to bring a little bit of that relentless robotic terror into your home, you can plunk down $500 for a sentient computer of your own (minus the actual sentience.) This HAL 9000 is better-behaved than the real thing. You still get the menacing red LED eye, but he won't try to kill you.… Read more

The new MySpace has launched to the public, and Justin Timberlake, the site's co-owner, is helping build some interest in it.

When folks head over to MySpace today, they'll find that they can now register to join the site. Upon doing so, users will be able to freely stream Justin Timberlake's new single featuring Jay Z, "Suit & Tie."

Until now, the new MySpace had been available only to those invited to try it out.

MySpace has gone through a series of reinventions over the years as it watched its star rise in the social-networking … Read more

You and I are really, really small. And we're even smaller than we thought we were last month, at least when compared with the size of the largest known item in the universe.

Last week, a team of astronomers based in the U.K. discovered the largest object in all of our observable existence: a celestial structure made up of 73 quasars that is up to 4 billion light years long.

How big is that exactly? Well, it would take tens of thousands of our own Milky Ways -- the big, galactic one, not the one that comes in … Read more

NASA has awarded a contract to explore ways to potentially expand the International Space Station.

The agency announced last week that Bigelow Aerospace has been awarded a $17.8 million contract to deliver to the agency an inflatable extension for the space station. According to NASA, the Bigelow Expandable Activity Module "will demonstrate the benefits of this space habitat technology for future exploration and commercial space endeavors."

Inflatable space technology is nothing new. In fact, the first passive communications satellites -- Echo 1 and Echo 2 -- were both inflatable. NASA determined in 1958 that the satellites would … Read more

The first American manned spacecraft to reach orbit in the wake of the shuttle's retirement will be crewed by company test pilots -- not NASA astronauts -- in part to give space agency managers better insight into flight readiness and safety, officials said Wednesday.

Assuming NASA gets the funding that managers say they need -- a big "if" in today's political environment -- Space Technologies Corp., or SpaceX, hopes to launch a manned version of its Dragon cargo ship in the mid 2015 time frame, followed by a crewed flight to the International Space Station later … Read more

At the center of our galaxy, chaos ensues: a supermassive black hole absorbs everything, young stars materialize, and elder stars explode. This violently beautiful cycle of activity creates galaxy-size bursts of charged particles that eject from the center of the Galactic Plane, and now you can see what those emissions look like.

Ettore Carretti, who works with Australian scientific research organization CSIRO, along with several other researchers around the world, describes the mega waves of energy in last week's issue of Nature. Team member Gianni Bernadi notes that the supersonic outflows -- which travel in excess of 621 miles per second -- originate from more than 100 million years of stars forming and exploding at the center of the Milky Way. … Read more

What if the Red Planet weren't always in that constant state of blushing? Kevin Gill, a software engineer who also re-engineers planets every now and then, imagines Mars might long ago have looked quite a bit more like the aqua-green marble we call home.

To create the above image, Gill used data from NASA's Mars Reconnaissance Orbiter (MRO), picked an arbitrary sea level, and used a script to cover all the surfaces of Mars below that line with a nice shade of royal blue. From there, Gill writes on Google+ that it was a combination of some earthly … Read more
