A major part of scouring the galaxy for alien lifeforms is listening for planets that our like ours, and signals like the ones we produce — radio waves, for instance. Astronomer Seth Shostak thinks we'd have a better chance if we started looking for more advanced life.
Out in what's known as the Virgo A galaxy is a black hole that's six billion times larger than our sun. That makes it a pretty good target for astronomers, who used the Chandra X-ray telescope and the Very Large Array to check the black hole out.
What would it be like to be hanging on to a rocket booster after it was ejected from the space shuttle, falling back to Earth? Wonder no more! NASA was kind enough to attach a camera to one of them as it did just that.
No, not that kind of space ghost. Say hello to the IRAS 05437+2502 nebula, which I'm just going to call Ira for the rest of this post. It doesn't just look spooky, either — we have no idea what's making it glow like this.
Just the other day we showed you one idea to clear the Earth's orbit of junk: giant balloons. Now, the Defense Advanced Research Project Agency is backing a proposal to build orbital vehicles that would scoop up debris in space using giant nets.
Robonaut 2, which will be the world's first robotic astronaut to work alongside its human counterparts up in orbit, is getting ready for its historic journey over at NASA's Kennedy Space Center in Florida. Just how does a 330-pound robot prepare, you wonder?
NASA plans to retire the International Space Station in 2020, and the agency is currently looking at ways that the venerable orbiter could further serve the world's space exploration needs. One idea? Using a module from the station to go check out asteroids.
I don't know when you were in space last, but it's pretty messy up there. Even the smallest piece of debris is dangerous to the operational satellites, spacecraft and the International Space Station. So, how do we clean it up? With balloons, according to Dr. Kristen Gates.
I've gotta give Xtraordinary Adventures credit for bringing the price of a flight to space down from the $200,000 Virgin Galactic is planning on charging. But still, $95,000 is a wee bit out of my price range.
I wouldn't recommend anyone wear the same pair of underwear for a full month without washing them; the results would not be pretty. But a new type of nanotechnology-infused underwear that are quick-drying and odor-absorbing? Well, if they're good enough for astronauts, they should be good enough for you.
