Travels at a blazing 28,164km/h, ISS finished that historic achievement only 92 minutes later. In its 18-year lifespan, the station has traversed about 4,254,047,000km, more than 28 times the distance of the earth to the sun. Damn, ISS.


Watch The Tycho Supernova Remnant Expand, Centuries After It First Exploded

Astronomers have used 15 years of X-ray data to make this video of the remnants of a white dwarf that famously exploded in 1572. Nearly 450 years later, the debris from the explosion is still expanding.


NASA Wants To Build A Magnetic Force Field And A Deep Sleep Chamber For Astronauts On Mars

A self-assembling space habitat, a deep sleep chamber to shuttle astronauts on long journeys and a protective magnetic force field are the latest projects NASA is embarking on.


A Major Mystery About Earth's Magnetic Field Has Just Been Solved

For the first time, physicists have observed a mysterious process called magnetic reconnection — wherein opposing magnetic field lines join up, releasing a tremendous burst of energy. The discovery, published in Science, may help us unlock the secrets of space weather and learn about some of the weirdest, most magnetic objects in the universe.


Hubble Just Caught A Close-Up View Of What Flying Into An Active Comet Looks Like

Comets brush by us all the time, but they’re usually not close enough for us to catch anything more than a glimpse as they streak through the sky. But, thanks to one very close comet, Hubble just got an incredible insider view.


A Huge Unnamed Dwarf Planet, Almost The Size Of Pluto, Has Been Hiding In Our Solar System

Image: Artist’s concept of 2007 OR10 / NASA In a universe full of planets, 2007 OR10 is something special. It’s big, just slightly smaller than the size of Pluto. And it’s close, within our very own solar system. So how did it still manage to take astronomers by surprise?


Kepler Has Nearly Doubled The Number Of Confirmed Exoplanets In Our Galaxy

Wait, you thought the Kepler Space Telescope was dead? Think again. Today, NASA’s Kepler team announced the discovery of a whopping 1284 new planets — the largest number of exoplanets ever reported at once. Kepler’s latest haul nearly doubles the number of confirmed planets beyond our solar system, bringing the total to roughly 3200.


Watch NASA's Beautiful Mercury Transit Time Lapse

Video: If you tried to to watch Mercury crossing in front of the Sun yesterday, chances are you didn’t get as good a view as NASA’s Solar Dynamics Observatory – especially since it wasn’t visible in Australia. Mercifully, the space agency has put together a stunning time lapse so you can watch the spectacle again.


Satellite Images Reveal The Horrific Scope Of Alberta's Bushfires

Bushfires continue to ravage the Canadian province of Alberta, and experts say they could double in size and take months to extinguish. Here are the latest space-based images of this unprecedented natural disaster.
