Last night's aurora painted the sky in reds, greens and even oranges. It's expected to return tonight!
Blue Origin needed a ship to catch rockets falling from space. They bought a massive roll-on/roll-off cargo ferry, hired engineers to convert it, and named it Jacklyn after Jeff Bezos's mother. Then, after four years of work, they scrapped the entire project and started over.
According to the textbook version of Solar System formation, planets should orbit the Sun in elliptical orbits, all lined up in the same plane. Jupiter, Saturn, Uranus, and Neptune don't follow this script. Their orbits are a little more elliptical and tilted relative to each other, not dramatically, but enough to puzzle astronomers for decades. Standard formation models predict the giant planets emerged from the protoplanetary disk on the same plane as the rest of the planets. Instead, something seems to have pushed them off course.
Early one February morning in 2025, Adam Borucki discovered something extraordinary behind his warehouse in Poland, a charred metal tank, roughly 1.5 metres across, sitting in his back yard. It had crashed from space during the night, part of a SpaceX Falcon 9 rocket that failed to complete its controlled descent into the Pacific Ocean. The debris damaged some electrical equipment and a concrete block. Nobody was hurt, but the incident raised an uncomfortable question; who pays when a private company's space hardware crashes into your property?
The supernova was the death of a red supergiant star 500 times larger than the sun, in a galaxy just 22 million light-years away.
New observations from the Virtual Telescope Project reveal 3I/ATLAS's sharply defined ion tail, highlighting increased activity as the interstellar comet moves through the inner solar system.
Auroras may be visible from Alaska to Illinois as an incoming coronal mass ejection could spark severe geomagnetic storm conditions overnight.
"Astronomers have wanted to spot a coronal mass ejection on another star for decades. We’ve now managed to do this for the first time."
Astronomers using the European Space Agency’s XMM-Newton space observatory and the LOFAR telescope have definitively spotted an explosive burst of material thrown out into space by another star – a burst powerful enough to strip away the atmosphere of any unlucky planet in its path.
A severe geomagnetic storm during a period of heightened solar activity has delated Blue Origin's second-ever launch of its New Glenn rocket, with NASA's twin ESCAPADE probes.
Does the APS-C sensor at the heart of the compact Nikon Z50 II punch above its weight when it comes to shooting for the stars and beyond?
Saturn's as edgy as it'll get for the next 13 years. With special visual treats in store, here's what to keep eyes on the planet this month.
The dome of the Gemini North telescope can be seen on top of Mauna Kea in Hawaii, with shimmering star trails and satellite streaks arcing overhead.
Astronauts lose significant amounts of muscle mass during any prolonged stay in space. Despite spending 2-3 hours a day exercising in an attempt to keep the atrophy at bay, many still struggle with health problems caused by low gravity. A new paper and some further work done by Emanuele Pulvirenti of the University of Bristol’s Soft Robotics Lab and his colleagues, describe a new type of fabric-based exoskeleton that could potentially solve at least some of the musculoskeletal problems astronauts suffer from without dramatically affecting their movement.
Vivid auroras lit up skies across North America and Europe as a severe G4 geomagnetic storm, one of the strongest this solar cycle, rattled Earth's magnetic field.
After a tense wait, it's finally been confirmed that Alien: Earth will return to our TV screens with more horrors in season 2.
Travelling up from Mars’s equator towards its north pole, we find Coloe Fossae: a set of intriguing scratches within a region marked by deep valleys, speckled craters, and signs of an ancient ice age.
"This study changes how we see the Pleiades — not just seven bright stars, but thousands of long-lost siblings scattered across the whole sky."

The year 2025 marked three decades of satellite navigation in Europe. To celebrate this milestone, on 2 September, the European Space Agency (ESA) opened the doors of ESTEC, its research and technology centre. Partners from across the continent joined a sensational event that took the audience on a journey through time, honouring the achievements and collaboration that have shaped the success story of the systems we rely on today: Galileo and EGNOS.
In 2023, gravitational wave detectors picked up the signature of a collision 7 billion light years away. Two black holes had merged in an explosion of warped space-time, but when astronomers analysed the data, they found something that violated the rules of physics. The black holes were spinning faster than any previously observed and fell within a mass range where black holes simply aren't supposed to exist.
