The Rosetta Image Archive Is Now Complete and Freely Available, so You Can See a Comet Like Never Before

The European Space Agency’s Rosetta mission to the comet 67P/Churyumov-Gerasimenko was one for the ages, providing an unprecedented look at this oddly shaped celestial object. The Rosetta probe captured nearly 100,000 images over the course of its mission, all of which are now freely available to the public in a single Rosetta archive. Read More >>

Forgotten Data From 1996 Sheds New Light on Jupiter’s Mysterious Moon Ganymede

Twenty-two years ago, the Galileo spacecraft made its first flyby of Ganymede, Jupiter’s largest moon. Scientists with NASA have taken a new look at the data collected during that historic encounter, providing tantalising new details about this strange celestial object, its unique magnetic shield, and its unusually bright auroras.

Our Galaxy Was Walloped by a Neighbour in Its Not-So-Distant Past, New Analysis Suggests

Space is a chaotic, ever-changing place. But that’s not limited to exploding stars and colliding black holes. Even our own Milky Way galaxy could have recently received a massive jolt from which it is still recovering. Read More >>

Gorgeous Photo of Martian Landscape Is Just the Beginning for ExoMars Mission

The ExoMars Trace Gas Orbiter has released the first images from its new orbit, taken on April 15 from 400 kilometres above the Martian surface. Here’s the uncropped composite image: Read More >>

NASA and ESA Are Getting Serious About Bringing Martian Soil to Earth

Earlier today, officials with NASA and the European Space Agency signed a statement of intent to explore the various ways in which Martian soil samples can be collected and delivered back to Earth. Sounds great, but a complex project of this nature won’t be easy, as it would involve the first-ever rocket launch from the surface of the Red Planet and a rendezvous in space. Read More >>

Incredible New View of the Milky Way Is the Largest Star Map Ever

The European Space Agency’s Gaia spacecraft team has dropped its long-awaited trove of data about 1.7 billion stars. You can see a new visualisation of all those stars in the Milky Way and nearby galaxies above, but you really need to zoom in to appreciate just how much stuff there is in the map. Yes, the specks are stars. Read More >>

Today’s Star Map Release Could Revolutionise Our Understanding of Astronomy 

Astronomers from the European Space Agency’s Gaia mission are releasing the biggest map of our galaxy ever today, using data collected by the Gaia space telescope. That includes 1.7 billion stars, as well as new information that could potentially solve some cosmic mysteries. Read More >>

Europe’s Gas-Sniffing Spacecraft Set to Science the Shit Out of Mars

After a year of steadily slowing down, the ExoMars spacecraft has finally reached its target orbit around Mars. In about two weeks, the European Space Agency and Roscosmos orbiter will begin to scan the Martian atmosphere in search of trace gases, including those potentially linked to life. Read More >>

The Hubble Space Telescope Captured This Beautiful Image of Two Galaxies Merging

NASA and the European Space Agency’s Hubble Space Telescope has been in low Earth orbit for nearly 28 years, but with several repairs and upgrades over the decades it’s still sending back beautiful images. Just a few days ago, the ESA released this Hubble image of a pair of barred spiral galaxies some 350 million light years away in the process of merging, their two galactic nuclei still separated by a massive distance but throwing out clouds of hot gas and mid-formation stars.

Scientists Observe Red Giant Waking Up Neutron Star in a Flash

Neutron stars aren’t the twinkle-twinkle kind you typically see in the night sky. They’re stellar corpses, and incredibly dense sources of gravity, with perhaps 1.5 times the mass of the sun packed into an area less than a dozen miles across. Around 9,000 light years away from Earth, one neutron stars seems to have befriended a red giant. And scientists observed the new relationship beginning in a flash of energy. Read More >>

Space-Based Gravitational Wave Observatory Passes Huge Test

Gravitational waves may be the most exciting thing in astronomy right now, but there are only so many things in space that scientists can study with Earth-based gravitational wave detectors. An incredible new test has demonstrated that space-based detectors could become a reality, which could open our ears to entirely new sources of gravitational waves. Read More >>

Colliding Neutron Star Discovery Could Solve This Mystery About Our Expanding Universe

Today, physicists across the world celebrated as telescopes and observatories on Earth and in space captured a “kilonova.” Two neutron stars collided 130 million light years away, sending gravitational waves, x-rays, gamma-rays, radio waves, and light waves to the Earth. But these events also serve as a new kind of tool—a tool with the potential to answer one of the most fundamental questions in our universe: How quickly is it expanding? Read More >>

The Most Overlooked Rocky Planet Is Getting Two New Visitors

Despite being closest to the sun, Mercury is the most ignored terrestrial planet in the solar system. It’s had to sit back and watch while Earth, Mars, and even Venus get all the attention. At night, if you listen closely, you can hear Mercury screaming into the dark void of space, begging for love. Read More >>

ESA Suggests 5G Delivered By Satellite Would Be Excellent

The European Space Agency is trying to drum up a bit of support for delivering 5G services via satellite. This is a departure from the current system of of huge masts dotted everywhere, although it's quite unlikely that satellites will totally replace these. Read More >>

Incredible First Person Footage of a Real Spacewalk Will Leave You Speechless

On March 24th, ESA astronaut Thomas Pesquet was joined by NASA astronaut Shane Kimbrough on a spacewalk outside the International Space Station. The outing was fairly routine, but this amazing footage captured by Pesquet gives all of us stuck here on Earth an amazing first-person look of what it’s like to be an astronaut looking down on our planet.
