The World's Deepest Pool Would Help Train Astronauts

Here’s a silly confession: I’m irrationally afraid of deep swimming pools. So when I first saw this rendering of what could become the world’s deepest “space pool”, my gut reaction was to turn off my computer and run for the hills. But the logical part of my brain reminded me that this would actually be pretty awesome.

This Is The Most Earth-Like Planet Ever Discovered

NASA’s Kepler Space telescope science team has just announced the discovery of the most Earth-like planet ever. Meet Kepler 452-b, the very first apparently rocky planet that definitively orbits a sun-like star in the habitable zone.

Today's Mission To The ISS Successfully Limped Home With Only One Wing

NASA's Incredible Expedition To Explore The Arctic Ice Sheets

Every spring, the scientists and flight crew of Operation Ice Bridge fly low over the Arctic, studying the Greenland ice sheet and nearby sea ice with high-resolution digital and thermal imaging cameras, a sophisticated radar suite, a laser altimeter and other instruments.

Pluto's Tiny Moons Are Coming Into Colourful Focus

Last week, Nix and Hydra transformed before our eyes from specks of light to bonafide moons. Today, NASA released a new set of images, bringing Pluto’s oblong satellites into even better focus. The latest astonishing finds? Nix has a rosy glow and Hydra has craters.
