Astronomers using the Atacama Large Millimeter Submillimeter Array have detected unusually high levels of methanol in the interstellar comet 3I/ATLAS, revealing a chemical composition rarely seen in comets formed within our solar system. The findings, reported by the National Radio Astronomy Observatory......
When NASA deliberately crashed a spacecraft into the asteroid moon Dimorphos in 2022, scientists quickly confirmed the collision shortened its orbit around its larger companion, Didymos. A new study now shows the impact also altered the path of the entire asteroid pair around the Sun, marking the first......
Physicists at the University of Oregon have produced the first computer model of an “ideal glass,” a theoretical form of matter in which molecules are packed as tightly and stably as possible while still maintaining the disordered structure typical of glass. The achievement, reported in Physical......
Scientists from the University of Warwick and the Massachusetts Institute of Technology have directly observed how microscopic networks on catalyst surfaces coordinate chemical reactions, challenging long standing assumptions about how catalysts function. The discovery could accelerate the development......
Researchers analyzing more than four decades of solar observations have discovered that the internal structure of the Sun changes subtly between periods of low magnetic activity, a finding that could improve predictions of solar storms and their effects on Earth. A team from the University of Birmingham......
A European Space Agency spacecraft traveling toward Jupiter has captured detailed images of the interstellar comet 3I/ATLAS, revealing a bright coma and a long tail of gas and dust as the rare visitor speeds away from the solar system. The observations were made by the Jupiter Icy Moons Explorer mission,......
Chinese researchers working on an ambitious space based solar power project say the technology could eventually serve purposes beyond clean energy generation, including the possibility of weakening typhoons and wirelessly recharging satellites across space. Duan Baoyan, the chief scientist behind China’s......
A Cornell led team has directly imaged atomic scale defects inside advanced computer chips, using a high resolution three dimensional electron microscopy technique developed with Taiwan Semiconductor Manufacturing Company and Advanced Semiconductor Materials. The method, based on multislice electron......
A rare planetary alignment will be visible this weekend as six planets—Mercury, Venus, Neptune, Saturn, Uranus, and Jupiter form an arc across the night sky. NASA says the so‑called “planetary parade” will peak on February 28, offering a fleeting chance to observe multiple planets......
Interstellar comet 3I/ATLAS is now racing away from the inner solar system after a fleeting but revealing visit that has given astronomers fresh insight into the chemistry of deep space. The icy body is only the third confirmed object known to have entered our planetary neighborhood from another star......
The rapid expansion of satellite constellations in low Earth orbit is drawing increasing concern from the scientific community. Researchers warn that the routine incineration of decommissioned satellites as they reenter the atmosphere could alter Earth’s climate and threaten the ozone layer. As......
Swarms of magnetic microrobots can now rotate and transport objects tens of thousands of times heavier than a single robot by stirring surrounding liquid instead of pushing directly on their targets. Each microrobot is a tiny disk roughly 300 micrometers across that spins under a controlled magnetic......
The Palestinian American chemist Omar Yaghi, who shared the 2025 Nobel Prize in Chemistry for pioneering metal organic frameworks, has turned a childhood shaped by water scarcity into a technology that can draw drinking water directly from the air, even in some of the driest places on Earth. His company,......
