Just in time: Scientists propose vaporizing asteroids

The sky is totally falling.

As if it weren't enough that a meteor boomed across the Russian sky today, shattering windows and injuring about 1,000 people, an asteroid 150 feet across is about to sideswipe our planet.

Asteroid 2012 DA14, while unrelated to the meteor, is just as scary. It will graze us at just 17,200 miles from the surface, passing between Earth and our geosynchronous weather and communications satellites.

Possible asteroid strikes are no joke, and if you ask me (or the dinosaurs), they represent the biggest threat to our planet aside from human stupidity.

Fortunately, some non-stupid humans are finally getting serious about countering this threat. … Read more

Injury count rises for Russian meteorite

The latest tally of meteorite-related injuries in Russia's Chelyabinsk region has reached about 1,000 -- most suffered from shards of glass that went flying when the meteor entered the atmosphere and sounded loud, window-shattering booms on its way to the ground earlier today.

Today has been an unusually active day for news involving big rocks from space. While the large Asteroid 2012 DA14 is passing closer to the surface of Earth than many of our satellites, an apparently unrelated meteorite streaked across the early morning Siberian sky, damaging buildings and thus injuring people in its path.

Clothes for Curiosity seekers: Mars inspires fashion line

Along with Bermuda shorts, bold stripes, and statement sunglasses, Mars is hitting the catwalk this year.

Fashion designer Nanette Lepore debuted her fall 2013 collection at Mercedes-Benz Fashion Week in New York yesterday, and it's all about the Red Planet. Bags and high heels that shimmer like mysterious, shiny objects. Mod and angular shapes. And lots of red.

"Moody tones and spacey surfaces define Nanette's fall collection as she explores the contours of Mars," read a pre-show teaser on the designer's tumblr blog. … Read more

Everything you need to know for Friday's big asteroid flyby

In less than 24 hours, a 150 foot-wide asteroid will complete a remarkably close, but safe, flyby. For weeks, scientists have been tracking the path of the small near-Earth asteroid known as 2012 DA14, which is on course to swing by the Earth tomorrow at 11:24 a.m. PT.

Again, no need to panic about a collision with Earth, which would be, in a word, catastrophic. If a space rock of this magnitude crashed into us, scientists say, it would release about 2.5 megatons of energy into the atmosphere. The last time an asteroid this size smacked into … Read more

NASA data may have uncovered galaxy's youngest black hole

Black holes are created when a supernova explosion destroys a massive star. Scientists have discovered dozens of black holes, but all of them are already formed. So, when scientists recently saw different distorted remains of a supernova, they knew it something special.

What the scientists believe they observed was the infant phases of a black hole, or the youngest black hole ever recorded in the Milky Way galaxy.

Caught on film by NASA's Chandra X-ray Observatory, the "remnant," or W49B, is seen as a vibrant swirl of blues, greens, yellows, and pinks. As seen from Earth, it … Read more

Astronaut records song from space with Barenaked Ladies

Chris Hadfield may well be the coolest astronaut in the galaxy.

He spends his time hosting Google+ Hangouts; giving tutorials on how to clip one's fingernails while on the International Space Station; tweeting with William Shatner; and playing space guitar. Space guitar is pretty much like regular guitar, except it happens in zero gravity while in orbit above the Earth on-board the ISS.

Hadfield has applied his space guitar skills to a recording session where he played and sang live along with the Barenaked Ladies and a choir. A large screen projected his part over video so everyone was on the same page during the session.… Read more

Another close asteroid encounter for Earth coming Friday

In a few days, sky watchers in Eastern Europe, Asia, and Australia will get a chance to see one big rock hurtling through the heavens. One very big rock. Compared with other asteroids traveling through space, this one may seem a relative pebble -- at half the size of a football field -- but for Earth, it will make for a relatively close call.

"This is a record-setting close approach," says Don Yeomans of NASA's Near Earth Object Program at JPL. "Since regular sky surveys began in the 1990s, we've never seen an object this big get so close to Earth." … Read more

Help name some Plutonian moons

Want to feel like you contributed to something important today? Take a moment to help rename two of Pluto's moons, which desperately need a little more pizzazz as they currently float around with the drab designations P4 and P5.

With assistance from the Hubble Space Telescope, astronomer Mark Showalter discovered P4 and P5 in 2011 and 2012, respectively. In conjunction with the SETI Institute, Showalter today opened a Web site that allows anyone to vote from 12 Greek and Roman mythology-inspired names for the roughly 20-mile diameter moons.… Read more

NASA launches Landsat Earth observation satellite

A United Launch Alliance Atlas 5 rocket blasted off from California and safely boosted a new Earth-watching Landsat into a polar orbit today to kick off an $855 million mission. It's the latest chapter in a 40-year program to monitor the planet's resources, land use, and environmental changes.

The Landsat Data Continuity Mission, or LDCM, got underway at 10:02 a.m. PT when the Atlas 5's Russian-designed RD-180 first-stage engine thundered to life and throttled up to full power with a rush of brilliant exhaust.

The towering 192-foot-tall rocket, generating some 860,000 pounds of thrust, … Read more

Neil deGrasse Tyson: Thor's hammer weighs 300 billion elephants

Beloved astrophysicist Neil deGrasse Tyson is no stranger to the world of comic book superheroes, having already found the location for Superman's home planet. He has now turned his keen scientific mind to the Marvel world and the issue of just how much Thor's mighty hammer weighs.

Thor's hammer Mjölnir is said to be made of neutron-star matter. Tyson did the calculations and determined the hammer must therefore weigh as much as 300 billion elephants. That's not a common form of weight measurement, so we have to do some further calculations to translate elephants into pounds.… Read more
