Planetary scientists weren't remotely expecting the 62-foot-wide Chelyabinsk fireball to shoot across Russian skies in February -- they'd had their eyes peeled on a much bigger target that missed the Earth by a decent margin, the asteroid 2012 DA14. But this relatively modest, unseen space rock caused a shock wave that shattered countless windows in the city and injured more than a thousand people. It was the largest asteroid impact on land in more than a century. Researchers are now saying that such impacts, from relatively small asteroids just tens of yards long, might be 10 times more common than we'd thought.

A massive asteroid the length of three football fields will make its closest approach to Earth tonight, and you can watch it fly by live, right here. Beginning at 6 p.m. PST, the astronomy website Slooh.com will provide a live video feed of the asteroid from a telescope in the Canary Islands. The free show will last about an hour and will be visible in the video box above. Asteroid the length of 3 football fields eludes sky-watchers The asteroid is known as 2000 EM26, and although it is big, it poses no threat to Earth.

Having trouble getting excited about NASA's planned mission to redirect an asteroid? Maybe William Gerstenmaier can help. "Turn off your logical side and turn on your touchy-feely side, the one you almost never use," Gerstenmaier, associate administrator for NASA's Human Exploration and Operations Directorate, told attendees of an aeronautics and astronautics conference Wednesday in San Diego. "Then jump up and down and do some break-dancing. We're going to grab a space rock and we're going to move it!"

ST. PETERSBURG, Russia -- Ukrainian astronomers say an asteroid might collide with Earth in a couple of decades, a Russian news service reported Thursday. Space watchers from the observatory in the Crimean peninsula said they discovered an asteroid about 1,345 feet in diameter, which they call 2013 TV135, that is approaching Earth at a potentially dangerous trajectory, RIA Novosti said. The astronomers calculated the date of a potential collision as Aug. 26, 2032, the news service said, but they acknowledged the odds of an impact as 1 in 63,000.

In a first, scientists have detected rings encircling an M&M-shaped asteroid known as Chariklo. Until now, only the solar system's four gas planets - Jupiter, Neptune, Uranus and especially Saturn - were known to have rings. "It was an extremely surprising discovery," said James Bauer, a planetary astronomer at NASA's Jet Propulsion Laboratory in La Cañada Flintridge who was not involved in the finding. "No one has ever seen rings around a comet or an asteroid before. This is a brand-new area.

A bizarre, never-before-seen asteroid with six comet-like tails has been found in the asteroid belt between Mars and Jupiter, and scientists are shocked. "I'm trying not to use the word 'freak,'" said David Jewitt of UCLA and lead author of a paper about the six-tailed asteroid, "but that's what it is. It is definitely freakish. " A NASA release described the asteroid as looking like "a rotating lawn sprinkler" with dust radiating out from it like spokes on a wheel. PHOTOS: Amazing images from space What makes this find especially weird is that asteroids almost never have any kind of tail at all. Those dramatic blue tails we see in images from space are generally associated with comets -- "dirty snowballs" that originate in the outer regions of our solar system.
