Chemical fingerprints from volcanic rock offer hints of what’s happening in the mantle below the area where three rift zones meet in East Africa

How do we know 3I/ATLAS, also called comet C/2025 N1 (ATLAS), is interstellar? Will it strike Earth? Can we visit it? Here are all of your questions answered.

Computers can help ensure that mathematical proofs are correct, but translating traditional maths into a machine-readable format is an arduous task. Now, the latest generation of artificial intelligence models is taking on the job, and could change the face of maths research

We spoke with NASA astronaut Matthew Dominick in an exclusive, first-ever interview from the cupola of the International Space Station.

Tissue samples sent to the International Space Station reveal what can happen to astronauts on long-term missions.

The skull of a 5-year-old girl who lived 140,000 years ago has similarities with modern Homo sapiens and Neanderthals, suggesting her parents might have belonged to different species

It's raining stars.

A collection of more than 50 pieces of memorabilia previously owned by Sally Ride, the first American woman to reach space, sold at auction last week for more than $145,000.

Surprising colors and stunning features are captured in a new image of Mars' surface.

In the latest attack on science by the Trump administration, researchers at the National Snow and Ice Data Center will no longer receive data from a fleet of military satellites.

Failed Orbital Mission Loses Human Remains, Space Pot

For long-duration missions, female astronauts generally use hormonal contraception to suppress their periods. But this method has potential health risks and requires special storage. Pads and tampons create waste in space. Now researchers have tested menstrual cups on a sub-orbital rocket flight, where they experienced the force of launch, and found they performed identically to ground control cups. This could provide a new option to female astronauts on future missions.

Rivers are one of the main ways that plastics get into the world's oceans, and now we can identify where plastic waste accumulates from space. Researchers used data from the Worldview-3 satellite to identify and map plastic material and polymer-coated surfaces in a watershed on the US-Mexico border. They collected different waste from stream channels and then identified their specific infrared absorption features, matching them to satellite imagery.
