All the supernovas ever photographed in one spectacular collection

NASA has revealed spectacular, newly reprocessed images of four of the most amazing supernovas ever captured by a human science instrument—the Crab Nebula (top), Tycho, G292.0+1.8, and 3C58—to celebrate the 15th anniversary of the Chandra observatory. I decided to go one step further and collect them all. » 7/22/14 8:05pm Yesterday 8:05pm

NASA space rover drives on the underside of the ice

NASA just completed a test of an early prototype—maybe just an early, early precursor—space rover that may be flown to explore the Jupiter moon Europa. What's cool is that the rover is designed to float on the underside of the ice and "rove as if the underside of the ice is the ground." Up is down, down is up. » 6/23/14 11:12pm 6/23/14 11:12pm

NASA makes zoomable Earth using 36,422 selfies from all continents

Not even Ellen DeGeneres can beat this one: NASA asked people to take selfies on Earth Day and humans from Antarctica to Zimbabwe submitted more than 50,000 photos. Of those NASA selected 36,422 photos to create this fully zoomable 3.2 gigapixel image of Earth's Eastern and Western hemispheres. » 5/22/14 12:56pm 5/22/14 12:56pm

Interstellar may be the first movie that shows realistic warp travel

At last we got to see the full trailer for Chris Nolan's Insterstellar. The drama seems centered around a worldwide food crisis fired by climate change and resource depletion—a quite probable future. The space travel part seems equally plausible, showing what may be the first realistic depiction of a real warp drive. » 5/16/14 3:17pm 5/16/14 3:17pm
