Yes, Time Travel Is Possible; Here's How

Time travel's been one of man's wildest fantasies for centuries. It's long been a popular trend in movies and fiction, inspiring everything from Charles Dickens' A Christmas Carol to H.G. Wells' The Time Machine to the Charlton Heston shrine that is The Planet of the Apes. And with the opening of Interstellar » 11/05/14 6:28pm 11/05/14 6:28pm

A Lunar Discovery Reveals The Secret To Building Deflector Shields

Radiation in space is one of the major obstacles to human exploration of the solar system. Astronauts on a round-trip to Mars could be exposed to radiation doses 66,000 times higher than on Earth. But recent research into magnetic fields on the Moon could help us design effective radiation shields. » 6/09/14 10:20am 6/09/14 10:20am

The Astronomer Who Wanted to Rearrange the Solar System, Using Nukes

CalTech astronomer Fritz Zwicky was the first to conceive of dark matter, supernovas and neutron stars. He also had a theory about colonizing the solar system using nuclear bombs. We could terraform other planets, he argued, by pulverizing them and then moving them closer or further from the sun. » 5/14/14 11:00am 5/14/14 11:00am

Scientists Build Incredible “Mars In A Bottle” Simulation Chamber

Environmental conditions on Mars are uniquely suited to destroying the billions of dollars of scientific equipment we send to study the Red Planet. To better protect our investments, three researchers have built a simulation chamber to assess the resilience of high-tech instruments before they are launched. » 4/09/14 11:20am 4/09/14 11:20am

Can Six Astronauts Live Together for 17 Months And Not Go Crazy?

The "Mars500" project was the most ambitious attempt yet to simulate the conditions of an expedition to the Red Planet. A newly published study assesses the psychological well-being of the crew during their "mission"—and reveals what it was like to live in cramped quarters with 6 people for 520 days. » 4/02/14 7:40am 4/02/14 7:40am

This is what it would really look like to travel at near-lightspeed

It's one of the most iconic images in all of science fiction: the stretching of stars as a ship makes the jump to lightspeed. But as a group of physics students at the University of Leicester has revealed, it wouldn't actually look like this. Instead, and assuming a ship could travel at nearly the speed of light, a… » 1/15/13 8:00am 1/15/13 8:00am
