Comet 67P/Churyumov-Gerasimenko Is Way Darker Than You Probably Realize

You'd never know from all the high-contrast photographs of Comet 67P/Churyumov-Gerasimenko that the comet is actually quite dark. This recently released composite image reveals how little light there is emanating from 67P/C-G, relative to other objects in our solar system. » 10/19/14 1:38pm Yesterday 1:38pm

This Eruption Spells Gently Impending Doom For A Hawaiian Suburb

An Astronaut Made This Floating Candy Corn Sphere For Science

Astronauts are allowed to bring special "crew preference" items with them when they go into space. NASA astronaut Don Pettit chose candy corn for his nearly six-month mission aboard the International Space Station. But, this candy had a destiny much greater than being a Halloween snack. » 10/17/14 8:25pm Friday 8:25pm

Does Saturn's 'Death Star' Moon Harbor A Hidden Ocean?

It's not the prettiest thing in the solar system, nor is it the most interesting. But Mimas — a pockmarked moon in orbit around Saturn — does exhibit a rather strange wobble. A team of astronomers say there can only be one of two explanations: either it's harbouring a subterranean ocean or it has an irregularly shaped… » 10/17/14 8:25pm Friday 8:25pm

Curious Signal Could Be Dark Matter Pouring From The Sun's Core

This could be historic: Astronomers from Leicester University have detected a strange signal in the X-ray spectrum that appears to be a signature of 'axions' — a hypothetical dark matter particle. It could take years to confirm, but this may be the first direct detection and identification of dark matter. » 10/17/14 8:24pm Friday 8:24pm

Here's What This Quadcopter Did After Losing Contact With Its Operator

Some quadcopters have this cool feature where upon losing contact with its operator they go into an automated Return To Home mode. But as this tragically comic video by Every Angle Films shows, the feature isn't always helpful — especially when a pesky mountain gets in the way. » 10/16/14 6:14pm Thursday 6:14pm

It's A Blast To The Prehistoric Past For National Fossil Day

It's National Fossil Day, a day designated to promote awareness of just how awesome fossils are. More importantly, it's a day when every fossil-loving person with a camera shares the treasures they've found, visited, or admired. Here's the best paleo-eye candy that crossed our path. » 10/15/14 10:00pm Wednesday 10:00pm

Why Did NASA Kill the One-Person Spacecraft?

On February 7, 1984, astronaut Bruce McCandless made history as the pilot for the test flight of the Manned Maneuvering Unit (MMU). On live TV, he backed away from the Space Shuttle Challenger, venturing 320 feet into space, becoming the first human satellite. But, by the end of the year, the MMU was mothballed. » 10/15/14 7:10pm Wednesday 7:10pm

This Is Precisely Where We'll Be Landing on Comet Churyumov-Gerasimenko

This is it folks, the area on Comet 67P/Churyumov–Gerasimenko where the Philae Lander will touch down on November 12. The ESA has officially given the green light for its Rosetta mission to deliver the lander in the first-ever attempt at a soft touchdown on a comet. We now have the timeline of events and an animated… » 10/15/14 7:10pm Wednesday 7:10pm

Study Reveals The Dust Bowl Was The Worst Drought In 1,000 Years

In the 1930s, the southwestern Great Plains suffered a series of severe droughts. Overfarming and overgrazing had destroyed prairie grasses, making the topsoil even more vulnerable to strong winds. NASA scientists now say that one of those drought years, 1934, was the driest and most widespread in a millennium. » 10/15/14 10:39am Wednesday 10:39am
