NASA's Roman Space Telescope has demonstrated remarkable pointing stability and given its powerful planet-imaging coronagraph its first look at the cosmos. The telescope can already stay locked on a target with precision comparable to aiming a laser ...

JWST has revealed that galaxies were spreading carbon, oxygen, and other heavy elements through space just 500 million years after the Big Bang. The surprising discovery suggests the young universe became chemically enriched much earlier than ...

Ultrashort electrical pulses allowed scientists to push superconductors closer than ever to the point where their electron pairs actually break apart. The method revealed hidden differences between superconducting materials and could open new ways to ...

Scientists at the University of Chicago have uncovered a surprising quantum state in the layered magnetic material Fe5GeTe2, where huge numbers of electrons move together unusually slowly while remaining quantum coherent. The behavior contradicts ...

A proposed qubit made with superfluid helium could cut quantum computing error rates by around 100 times by shielding quantum information from common forms of electromagnetic noise. If experiments confirm the predictions, the technology could ...

UCLA researchers built an AI system that uses light to analyze more than a dozen videos simultaneously, detecting deepfakes with nearly 98% accuracy. Its speed, low energy demands, and resistance to attacks could make it a powerful tool for screening ...

Researchers have experimentally observed energy patterns that physicists have predicted for about 40 years. By arranging laser-trapped atoms into a quantum simulator, they recreated two different quantum tipping points and watched the atoms fall into ...

Astronomers have found strong evidence that some mysterious, minutes-long X-ray flashes are produced when two neutron stars collide and create a magnetar. One record-setting event glowed in X-rays for nearly 10 minutes, potentially opening a new way ...

NASA's Perseverance rover has uncovered a surprisingly complicated history of water in Jezero Crater. Scientists expected the crater's Margin Unit to contain lake sediments, but instead found ancient igneous rocks that were altered by water on at ...

Powerful jets from supermassive black holes can disturb star-forming gas far beyond a galaxy's visible edge, leaving a glowing trail hundreds of thousands of light-years long. By keeping this gas hot and preventing it from falling inward, the jets .. ...
