Which Religions Would Have The Hardest Time Accepting Alien Life?

The list of known planets beyond our solar system is ever-growing. To many, this suggests the day when scientists detect signs of extraterrestrial life could soon be at hand. When that day comes, which religions will struggle to reconcile such a discovery with their beliefs – and which will adapt in stride? » 10/17/14 3:40pm Friday 3:40pm

White House Seeks Advice On "Bootstrapping A Solar System Civilization"

The White House Office of Science and Technology Policy is planning ahead — way ahead. The agency wants you to email ideas for how "the Administration, the private sector, philanthropists, the research community and storytellers" can develop "massless" space exploration and a robust civilization beyond Earth. » 10/17/14 8:30am Friday 8:30am

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 2:58pm Wednesday 2:58pm

MIT Study Says Mars One Colonists Would Starve (Among Other Things)

Mars One may have taken us by surprise when the non-profit organization boldly announced that it would put colonists on Mars in the 2020s.

However, MIT students believe the effort, in its current form, is doomed… » 10/12/14 4:43pm 10/12/14 4:43pm

A Brief History of Scientists Hunting for Time Travelers

Time travel is possible—or at least a lot of serious physicists say so. It's probably not possible to pull it off in a souped-up Delorean, but there are wormholes, Tipler cylinders, and other Einstein-inspired theories for how it could work. Which raises the question: Why haven't we met any visitors from another time? » 10/09/14 3:39pm 10/09/14 3:39pm

Doctored 3D Models Of The Rosetta Comet Are the Best

As the Rosetta spacecraft acquires more precise measurements of the comet 67P/Churyumov-Gerasimenko, scientists are able to create detailed 3D models. Last week, the ESA made that data available for downloading, allowing people to make their own comet replicas—sometimes, with a few creative embellishments. » 10/09/14 11:47am 10/09/14 11:47am
