Crash boom bang! Our planet and another protoplanet may have collided head-on in their early history.

NASA finds vast quantities of frozen water on Pluto

NASA.

New data provided by the New Horizons mission showed that water ice on Pluto is much more common than we thought.

China’s National Space Administration released a trove of images from their lunar rover and they’re spectacular. We’re talking hundreds of tantalizing, HD and never-before-seen images of the Moon! You can set up an account on China’s Science and Application Center for Moon and Deepspace Exploration website and have a look for yourself, view and download all the pictures you like – but

Europe launches laser-equipped satellite to transmit data – 100 times faster than the internet

EDRS will eventually feature several relay satellites in orbit, gathering data and speeding it to the ground. Image via ESA.

Europe’s laser communication network has taken off!

We have a ninth planet in the solar system – and it’s not Pluto

A duo of astronomers from CalTech may have found another planet, far away in our solar system.

NASA’s solar-powered Juno shuttle breaks record distance at 793 million km from the Sun

Juno is part of NASA’s New Frontiers program that wants to get up-close and personal with several planets in our solar system. The shuttle itself is going towards Jupiter to study its gravity field, magnetic field, and polar magnetosphere. Juno will also search for clues about how the planet formed, including whether it has a rocky core, the amount of water present within

Water ice found on a comet

For the first time in history, astronomers have solid clues of water ice on a comet, confirming what many theories already claimed.

Astronomers detect biggest explosion we’ve seen

The star was observed for the first time in June, but it’s still radiating massive amounts of energy, making it shine 570 billion times stronger than our Sun.

Jaw-dropping high-res images of Pluto show a sea of nitrogen

The New Horizons shuttle has finished its Pluto flyby months ago, but NASA is continuing to receive breathtaking photos from it. The latest additions paint a ‘lava lamp’ surface on Pluto’s surface, likely a sea of nitrogen close to Pluto’s Sputnik Planum. Astronomers knew that Sputnik Planum was an icy plain, irregular and segmented by massive troughs, but now they

First ‘growth chart’ developed for the Milky Way

The Milky Way has been around for at least 13.7 billion years, but it has its younger and older areas.
