JWST has revealed that young planetary systems lose their planet-building gas through a changing mix of powerful jets, molecular winds, and radiation-driven outflows. As the disks age and their gas disappears, giant planets face a shrinking window to ...

Measurements of ancient light from the cosmic microwave background suggest that the universe is remarkably flat. But that does not prove it is infinite, because the observable cosmos could be only a small patch of a much larger curved universe. Space ...

Scientists recreated a particle-forming process linked to the extreme physics of the early universe using a 13-ion quantum simulator. The breakthrough suggests quantum computers could eventually help researchers investigate how matter formed and ...

Artemis II astronauts Victor Glover and Reid Wiseman are transitioning to emeritus status at NASA after their historic journey around the Moon earlier this year. The pair will continue advising and mentoring NASA teams as preparations accelerate for ...

Scientists think beneficial fungi could help transform nutrient-poor lunar and Martian regolith into a material capable of supporting crops. By helping plants access nutrients and withstand harsh conditions, these microbes could someday make self ...

CERN has started replacing some of the Large Hadron Collider's most important magnets as part of its High-Luminosity upgrade. The new superconducting magnets will produce fields about 40% stronger, allowing particle beams to be squeezed more tightly ...

Researchers have shown that exotic quantum particles called non-Abelian anyons can perform the full range of operations needed for universal quantum computing. Using 54 qubits on Quantinuum's H2 processor, they combined braiding and fusion to unlock ...

A dead white dwarf with no detectable disk has somehow produced a powerful shock wave that appears to have persisted for at least 1,000 years. Its magnetic field may be partly responsible, but astronomers say an unexplained "mystery engine" may also ...

Ancient grains inside one of the oldest known meteorites reveal that a surprisingly strong magnetic field existed during the solar system's first 200,000 years. The discovery suggests magnetism worked alongside gravity to help transform a vast cloud ...

Researchers have shown that multiple time crystals inside a semiconductor can synchronize their oscillations, much like pendulum clocks gradually falling into the same rhythm. The coupling is carried by spin-polarized electrons, allowing time ...
