Up to 150 shooting stars may brighten the night sky each hour during the Dec. 13 peak.
Radio astronomy has a pollution problem. Satellites thousands of kilometres overhead, designed to broadcast communications or relay data, are increasingly contaminating the frequencies astronomers use to study the universe. While much attention has focused on SpaceX's Starlink and other low Earth orbit constellations, but what about the satellites much farther away?
A satellite that rode to space Dec. 9 on a Chinese rocket nearly slammed into one of SpaceX's Starlink internet spacecraft, according to the company.
The seven members of the Expedition 74 crew studied stem cells, packed up a cargo ship and maintained their toilet this week aboard the International Space Station.
The inaugural ceremony was held at London's Natural History Museum on Dec. 5.
"This is a real gift for physicists as we confirm predictions made more than a century ago."
Sci-fi adventure Exodus is looking alright, alright, alright.
The Geminid meteor shower peaks overnight this weekend. Here's when to look for the most shooting stars — and where to aim your gaze.

A strange, spider-like scar on Jupiter's icy moon Europa may mark where salty water once surged up through its fractured crust.
What could force a supermassive black hole (SMBH) out of its host galaxy? They can have hundreds of millions, even billions of solar masses? What's powerful enough to dislodge one of these behemoths?
On July 1st, 2025, the third interstellar object (ISO) ever detected was seen making its way through our Solar System. Shortly after being alerted by automated detection systems, astronomers at the European Space Agency (ESA) began using observatories in Hawaii, Chile, and Australia to get a better look at the interstellar interloper. Since then, 3I/ATLAS has been observed by multiple space observatories, including the venerable NASA/ESA Hubble Space Telescope. On Nov. 30th, Hubble viewed the ISO again, which is about to make its closest approach to Earth.

One of the biggest impacts to the low Earth orbit environment in the near-term and long-term future are satellite megaconstellations, according to a new study, published in the journal Nature. Companies, like Amazon, OneWeb and SpaceX, along with governments, like China and the United States are keen on the idea of controlling hundreds, thousands or even tens of thousands of satellites that serve a connected purpose.
The Geminid meteor shower peaks Dec. 13–14, and the U.S. weather forecast will play a key role in what you'll see.
When astronauts finally set foot on Mars, they'll arrive carrying the weight of centuries of speculation about whether life exists beyond Earth. Now a new report from the National Academies has settled a fundamental question about priorities: searching for evidence of past or present Martian life should be the primary science objective for humanity's first crewed mission to the red planet, ranking above all other scientific goals including understanding the effects of Mars on human health.
If you didn't stay up to watch The Game Awards 2025, here's the complete rundown of the hottest sci-fi and space games that appeared at the show.
