Astronomers have solved a 170-year-old planetary mystery in a nearby two-star system, discovering that a mysterious wobble was caused by stellar activity rather than a giant planet. Although Jupiter-sized worlds have been ruled out in key regions, .. ...

NASA's Juno spacecraft has discovered that Jupiter uses a surprisingly complex system of powerful plasma waves and multiple shock regions to defend against the solar wind. The findings reveal major differences between Jupiter and Earth and could help ...

Mathematicians have uncovered what they argue is a fundamental flaw in the standard model of the universe, potentially challenging the need for dark energy. Their calculations suggest that the mathematical framework used to describe cosmic expansion ...

Scientists have defied a long-standing rule of laser physics by generating X-rays with much higher energies than conventional theory predicts. The surprising discovery reveals how two electrons working together can overcome a previously accepted ...

Scientists have uncovered seven surprising stages that space rocks go through as they hurtle toward Earth, revealing that melting and violent fragmentation, rather than simple evaporation, determine their fate. The discovery could help explain why .. ...

Scientists have developed a new technology that could make electric vehicle batteries smaller, lighter, and longer-lasting, potentially allowing cars to travel farther on a single charge. By borrowing precision manufacturing techniques from computer ...

NASA's Artemis I mission has revealed that cosmic radiation near the Moon is higher than in Earth orbit, but not by as much as scientists might expect. Tiny experimental detectors also uncovered surprising details about how radiation passes through . ...

A scorching lava planet 280 light-years away has surprised astronomers by apparently maintaining a thick atmosphere despite conditions that should have stripped it away billions of years ago. James Webb Space Telescope observations suggest that TOI . ...

Scientists have created one of the largest and most detailed simulations of the early universe ever made, offering an extraordinary new glimpse into the cosmos shortly after the Big Bang. Called Lumina, the groundbreaking simulation recreates the ...

Scientists at UC San Diego have developed a surprising new way to store digital information using light instead of magnets, potentially paving the way for smaller, faster, and more energy-efficient memory devices. By precisely shaping and shrinking . ...
