‘Black hole stars’—Webb finds strongest evidence yet

The complex puzzle known as little red dots has become more complete since their initial discovery by NASA’s James Webb Space Telescope in 2022. Now a particular little red dot’s spectrum is helping connect many of the pieces.

Small optical component could change how telescopes view the sun

A new telescope technology—measuring just 6 millimeters (0.24 inches) in diameter—could improve how future space missions study and monitor the sun while simplifying onboard hardware and reducing costs.

Where not to look in the search for ET

There’s a question at the heart of SETI that doesn’t get nearly enough attention. It isn’t whether aliens exist, and it isn’t whether we have the technology to detect them. It’s a far more practical problem: With a billion stars in our galaxy and finite telescope time, how do you decide which ones to actually […]

A meteorite impact may have once rained gold on Western Australia

We’re used to a lot of different natural things falling out of the sky. These can include snow, rain and sometimes even frogs (yes, really). All of these relate to weather phenomena.

Astronomers find a four-carbon sugar in deep space

The space between stars may seem like a barren desert, but over the past few decades scientists have been finding all sorts of interesting chemicals in it. From the precursors to proteins to the building blocks of cell membranes, there has been discovery after discovery of new molecules in the giant gas clouds between the […]

Galaxy-killing wind discovered in the early universe

Astronomers have discovered a “galaxy-killing wind” that may explain why there are far more massive “dead” galaxies than expected in the early universe. This wind, powered by cosmic collisions between galaxies, could quickly blow away all the fuel for new stars, leaving a galaxy on the brink of death and helping to solve one of […]

Majorana modes withstand disorder in atomic chains, boosting fault-tolerant quantum computing

Quantum computers—systems that process information and perform computations by leveraging the principles of quantum mechanics—could solve some tasks faster and more effectively than classical computers. While some studies have demonstrated the advantages of these computers for specific tasks, ensuring their reliable operation in real-world settings has proved challenging.

JWST reveals dawn-dusk atmosphere split on ultra-hot exoplanet WASP-121 b

Astronomers have revealed distinct differences in atmospheric conditions between the morning and evening transition zones of the ultra-hot gas planet WASP-121 b, which separate day from night, commonly called terminators. This achievement was only possible due to the unmatched sensitivity of the James Webb Space Telescope (JWST).

Quantum witness technique reveals spinons in quantum spin liquid candidate

Physicists at University College Cork have developed a new approach in the search for a quantum spin liquid, a long-sought state of quantum matter resembling a magnetic liquid whose quantum properties mean it never freezes. The work is a key step in the search for quantum silicon, a mineral that could be used to create […]

To discover new physics, AI may need to ‘unlearn’ the old one

A study in the Journal of Cosmology and Astroparticle Physics explores how a machine-learning strategy known as transfer learning could dramatically reduce the computational cost of searching for new physics beyond the standard cosmological model—while also revealing an unexpected risk: Sometimes AI systems can become too reliant on what they already know.
