Mars Orbiters Survive Unprecedented Encounter With Comet Siding Spring

Yesterday, comet Siding Spring hurled past Mars at half the distance between the Earth and moon, bringing a massive cloud of dust along with it. To protect its space-based assets, space agencies employed precautionary measures, and they appear to have worked. » 10/20/14 8:20am Today 8:20am

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 10:20am Friday 10:20am

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 8:00am Friday 8:00am

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 2:58pm Wednesday 2:58pm

Want to Stay Healthy? You'll Need to Become a Human-Animal Hybrid.

Biologists have been mixing the DNA of different animals since the 1970s, but the idea of injecting the genes of animals into humans remains taboo. Called transgenics, it's a practice that could cure illness in the future — and eventually reshape our species. Here's what you need to know about it. » 10/15/14 11:25am Wednesday 11:25am

Popping Frozen Poop Pills Can Stave Off Dangerous Bacterial Infections

Fecal transplants are an effective way to combat C. difficile infections, but they're typically delivered by enema or a tube down the digestive system. Not pleasant. But thankfully, scientists from Massachusetts General Hospital have now made the healing powers of poop available in pill form. » 10/14/14 6:00pm 10/14/14 6:00pm
