Observations by NASA’s SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer) show the infrared light emitted by the dust, water, organic molecules, and carbon dioxide contained within comet 3I/ATLAS’s coma.

So we did that. And we found nothing. So far, with all of our experiments around the world, we find no evidence of missing momentum, and no signs of towers of gravitons slipping away into hidden dimensions.

Astronomers used the XRISM x-ray satellite to observe two supermassive black holes in two separate galaxy clusters. Researchers know that SMBH have powerful effects on star formation and galaxy evolution. The observations reveal new details in how it all works.

The American Medical Association is launching an effort to evaluate vaccine safety and effectiveness independently of U.S. government health agencies

Most galaxies don't have any rings -- why does this galaxy have three?

Upgrading to the latest cameras may require changing your imaging techniques.

Building the human story based on a few artefacts is tricky – particularly for wooden tools that don’t preserve well, or cave art that we don’t have the technology to date. Columnist Michael Marshall explores how we determine what came first in the timeline of our species

A pair of CubeSats designed by college students from around the world is deployed into Earth orbit from a small satellite orbital deployer on the outside of the International Space Station's Kibo laboratory module. Students from Mexico, Italy, Thailand, Malaysia, and Japan designed the shoe-boxed sized satellites for a series of Earth observations and technology demonstrations.

Once considered an oddity of quantum physics, time crystals could be a good building block for accurate clocks and sensors, according to new calculations

An experiment to quantify the amount of the universe’s lightest element in Earth’s core suggests that the planet’s water has mostly been here since the beginning

If a pulsar that may lie at the center of our galaxy is confirmed, it could enable more precise measurements of the spacetime around the Milky Way’s central supermassive black hole

Networks of molecules in our body behave as though they have goals and desires. Understanding this phenomenon could solve the origins of life and mind in one fell swoop

The 4-billion-year-old Moon rocks brought back from the farside of the Moon challenge ideas about what it was like in the early solar system.

Electric vehicle batteries are typically retired once they reach about 80 per cent of their original capacity, but they could be repurposed in electricity grids to balance out slumps in renewable generation

On 10 February 2026, the European Space Agency (ESA) signed a contract with OHB Italia for the development of the Rapid Apophis Mission for Space Safety (Ramses). Launching in 2028, Ramses will rendezvous with the asteroid Apophis before its rare close encounter with Earth. The mission will provide unique insight into the physical properties and behaviour of asteroids, and strengthen international collaboration and European capabilities in planetary defence.
