NASA has bumped two female astronauts. including the commander, from the next SpaceX crew rotation flight to the international space station, freeing up two seats to give the agency’s Starliner astronauts a ride home next February.
Explore the greatest sci-fi titles that emerged amidst rock, roll, and the Golden Age in our round-up of the best 50s sci-fi movies.
Intuitive Machines, which aced the first-ever private moon landing earlier this year, just scored a $117 million NASA contract for a 2027 mission to the lunar south pole.
Want a clear view of a supermassive black hole’s environment? It’s an incredible observational challenge. The extreme gravity bends light as it passes through and blurs the details of the event horizon, the region closest to the black hole. Astronomers using the Event Horizon Telescope (EHT) just conducted test observations aimed at “deblurring” that view.
NASA's Perseverance Mars rover has started off on its most ambitious ascent yet to the rim of Jezero Crater.
NASA's Crew-9 mission now has only 2 astronauts instead of 4. The last-minute change gives room to return 2 astronauts on the ISS who needed a new ride home.
NASA astronauts Butch Wilmore and Sunita Williams will spend at least eight consecutive months aboard the International Space Station as their Boeing Starliner spacecraft returns to Earth empty. Is their extended spaceflight record-setting?
The first of a set of groundbreaking Cluster satellites is set for a controlled reentry next week.
We provide the latest details on this comet, which might (or might not!) blossom into a bright naked-eye object in our October evening skies.
Black holes may be behind why the newborn universe appeared to possess more huge galaxies than scientists could explain, a new study finds.
Astronomers used artificial intelligence to calculate the five cosmological parameters that describe the entire universe in computer simulations with unprecedented precision.
Low in twilight, climbing Venus and descending Spica prepare to pass each other. After dark Vega crosses the zenith, and Scorpius beds down. Mercury shines at dawn.
As it’s name suggests, dark matter is dark! That means it’s largely invisible to us and only detectable through its interaction with gravity. One of the leading theories to explain the stuff that makes up the majority of the matter in the Universe are WIMPs, Weakly Interacting Massive Particles. They are just theories though and none have been detected. An exciting new experiment called LUX-ZEPLIN has just completed 280 days of collecting data but still, no WIMPs have been detected above 9 Gev/c2. There are plans though to narrow the search.

Sentinel-2C is ready for launch! The new satellite will soon join its Copernicus Sentinel-2 family in orbit – where it will continue to provide detailed views of Earth’s land and coastal waters.
Discover where space begins: the guide to ESA’s establishments
ESA's Prospect package, including drill and a miniaturised laboratory, will fly to the Moon’s South Polar region in search of volatiles, including water ice, as part of NASA’s Commercial Lunar Payload Services initiative.
When the James Webb Space Telescope provided astronomers with a glimpse of the earliest galaxies in the Universe, there was some understandable confusion. Given that these galaxies existed during “Cosmic Dawn,” less than one billion years after the Big Bang, they seemed “impossibly large” for their age. According to the most widely accepted cosmological model—the Lambda Cold Dark Matter (LCDM) model—the first galaxies in the Universe did not have enough time to become so massive and should have been more modestly sized.
The merging of black holes and neutron stars are among the most energetic events in the universe. Not only do they emit colossal amounts of energy, they can also be detected through gravitational waves. Observatories like LIGO/Virgo (Laser Interferometer Gravitational Wave Observatory) and KAGRA (The Kamioka Gravitational Wave Detector) have detected their gravitational waves but new gravitational wave observatories are now thought to be able to detect the collapse of a massive rapidly spinning star before it becomes a black hole. According to new research, collapsing stars within 50 million light years should be detectable.
Boeing's troubled Starliner capsule is poised to return to Earth without any crew aboard on Sept. 6, NASA announced on Thursday (Aug. 29).
The search for extraterrestrial intelligence (SETI) has fascinated us for decades. Now a team of researchers have used the Murchison Widefield Array in Australia to scan great swathes of sky for alien signals. Unusually for a SETI project, this one focussed attention on 2,800 galaxies instead of stars within our own. They have been on the lookout for advanced civilisations that are broadcasting their existence using the power of an entire star. Alas they weren’t successful but its an exciting new way to search for alien intelligence.
