On Friday, asteroid 2014-YB35 is expected to make its closest approach to Earth. Traveling at over 23,000 mph (37,000 km/h), NASA says the 6.2 mile (1,000 meter) asteroid won't get any closer than 2.7-million miles (4.4 million km). That's nearly 12 times the distance from Earth to the Moon – so relax. » 3/26/15 2:40pm Thursday 2:40pm

Aussie Scientists Say This Is The Largest Asteroid Impact Area On Earth

Measuring 250 miles (400 km) wide, the now-buried crater in Australia was ground zero for a cataclysmic impact that occurred some 300 million years ago. But is it really the largest on Earth? » 3/24/15 9:40am 3/24/15 9:40am

The Number of Asteroids We Could Visit and Explore Just Doubled

There's a famous line from Shakespeare's Hamlet that says "There are more things in heaven and Earth, Horatio, than are dreamt of in your philosophy," and the same now holds true for brave new worlds for humans to explore. » 2/12/15 2:40pm 2/12/15 2:40pm

A Massive Asteroid Strike Could Have Sparked Life On Earth

By using lasers to simulate the impact of a large meteor with primordial Earth, researchers have shown how the atom bomb-like collisions might have reconstituted ordinary molecules into the early building blocks of life. » 12/09/14 10:40am 12/09/14 10:40am

Philae's Discovery Of Organic Molecules Is Actually Not A Big Deal

Prior to going into hibernation mode, the Philae lander hurriedly conducted a number of experiments and sent its findings back to Earth. Preliminary analysis shows that the icy and dust-covered comet contains organic molecules. It's a cool discovery, no doubt, but one that shouldn't be exaggerated in terms of its… » 11/19/14 9:40am 11/19/14 9:40am

What In The Hell Caused This Enormous Flash Over Russia?

An ominous dash-cam video has captured an extraordinarily bright orange flash in Russia's Sverdlovsk region in the Urals. Though the event was witnessed by many onlookers, there's still no explanation for what appears to be a rather massive blast. » 11/19/14 7:20am 11/19/14 7:20am

The Timing Of Meteor Strikes May Not Be Random

Astronomers tend to assume that the timing of Earth-striking meteors are completely random, but a recent analysis suggests that meteor impacts are more likely to occur at certain times of the year and at certain locations. » 9/29/14 7:20am 9/29/14 7:20am

Congressional Hearing Slams Feasibility Of Commercial Asteroid Mining

Two congressmen recently introduced the ASTEROIDS Act, which would grant property rights to companies seeking to mine the asteroid belt. Yesterday, the House Space Subcommittee held a hearing on the bill, where expert testimony bluntly told Congress the private sector is not up to the task of mining in space. » 9/11/14 9:40am 9/11/14 9:40am

Can Congress Grant Private Companies The Right To Mine Asteroids?

U.S. companies are eyeing asteroids as the next frontier in lucrative mining ventures. But, they say, their plans are stymied by the vague status of private ownership in space. Earlier this summer, members of Congress introduced a bill to protect property rights for commercial exploitation of asteroids. Is that legal? » 8/14/14 12:00pm 8/14/14 12:00pm

The Tortured History Of Earth's First 500 Million Years

New research suggests the Earth was pummelled by four gigantic asteroids measuring at least 600 miles across in its early days — impacts that would have rebooted the surface, boiled off the oceans, and extinguished any fledgling life. Here's what we now know about the Late Bombardment Era and its affect on our… » 7/31/14 1:15pm 7/31/14 1:15pm

"Colossally Poor Timing" of Asteroid Caused Dinosaur Extinction

Researchers from the University of Edinburgh say the dinosaurs might have survived the asteroid strike that wiped them out had it happened slightly later or earlier in history. » 7/28/14 8:00am 7/28/14 8:00am

How Brazil Nuts Solved A Mystery About Asteroids

When Japan's Hayabusa spacecraft photographed the asteroid Itokawa in 2005, scientists were puzzled by what they saw: The total volume of boulders strewn about its surface were greater than the volume of the craters they were supposed to have come from. Now physicists have an answer... by studying the movement of nuts. » 7/16/14 7:20am 7/16/14 7:20am

Every Asteroid Discovered Since 1980

From the far, far away to the startlingly close, there have been over 600,000 asteroids identified in the inner solar system since 1980. This visualization tracks them all. » 6/12/14 4:20pm 6/12/14 4:20pm

Giant Asteroid Zooms Close to Earth, Revealing an Odd Shape

A near Earth brush — but not close enough for impact — by this giant 1,200 foot asteroid provided the perfect opportunity to get a closer look at the asteroid (and its odd shape, like a slightly jagged peanut) with these pictures, some of the sharpest images of an asteroid ever taken. » 6/12/14 11:22am 6/12/14 11:22am

CNN Needlessly Terrifies Thousands By Publishing Asteroid Hoax

Earlier this week — and for a period of nearly 24 hours — a CNN iReport falsely claimed that a newly discovered asteroid has a nearly 50% chance of hitting the Earth in 2041. The story received more than 230,000 hits and 23,000 media shares before it was finally taken down. » 5/28/14 11:00am 5/28/14 11:00am

A Visualization Showing Where Asteroids Have Hit The Earth Since 2001

A new visualization produced by the B612 foundations reveals 26 significant explosive events recorded from 2001 to 2013 that were not the result of nuclear detonations — but rather asteroids hitting the Earth. That's a surprise, to say the least. » 4/22/14 3:08pm 4/22/14 3:08pm

This Ancient Asteroid Strike Was More Insane Than We Realized

Around 3.26 billion years ago — long before the dinosaurs — a massive asteroid measuring nearly 36 miles (58 km) across smashed into the Earth. Geologists have now reconstructed this cataclysmic event, and it was far, far bigger than we thought. Here's how things went down on that fateful day. » 4/10/14 12:00pm 4/10/14 12:00pm

Why are there square craters forming on the Moon?

The moon is full of craters both large and small, but typically they come in only one shape: round. So why are scientists spotting square craters on the moon? » 3/07/14 2:49pm 3/07/14 2:49pm

What caused this huge asteroid to disappear mysteriously?

200,000-ton asteroids don't usually just disappear into space (okay, maybe sometimes do), but when astronomers at NASA trained the Hubble on this asteroid, they were puzzled to see it was falling apart right before their eyes, the first time they'd ever seen such a sight. » 3/06/14 6:00pm 3/06/14 6:00pm
