Scientists observing the red giant star R Doradus have found that starlight isn't strong enough to drive its stellar winds, overturning a long-standing theory. The dust grains around the star are simply too small to be pushed outward by light alone. ...

Scientists at Fermilab's MicroBooNE experiment have ruled out the existence of the elusive sterile neutrino, a particle proposed for decades to explain puzzling neutrino behavior. Their high-precision measurements showed neutrinos behaving exactly as ...

The accelerating expansion of the universe is usually explained by an invisible force known as dark energy. But a new study suggests this mysterious ingredient may not be necessary after all. Using an extended version of Einstein's gravity, ...

Scientists have discovered an enormous stream of super-hot gas erupting from a nearby galaxy, driven by a powerful black hole at its center. The jets stretch farther than the galaxy itself and spiral outward in a rare, never-before-seen pattern. NASA ...

Scientists have unveiled a new way to capture ultra-sharp optical images without lenses or painstaking alignment. The approach uses multiple sensors to collect raw light patterns independently, then synchronizes them later using computation. This ...

Crystals hidden in Australia's oldest rocks have revealed new clues about how Earth and the Moon formed. The study suggests Earth's continents didn't begin growing until hundreds of millions of years after the planet itself formed. When scientists .. ...

Astronomers have uncovered the long-hidden cause behind Betelgeuse's strange behavior: a small companion star carving a visible wake through the giant's vast atmosphere. Using nearly eight years of observations from NASA's Hubble Space Telescope and ...

Hubble has revealed a strange cosmic object called Cloud-9, a dark matter-dominated cloud with no stars at all. Scientists believe it is a "failed galaxy," a leftover building block from the early Universe that never lit up. Its discovery confirms .. ...

Scientists in South Korea have discovered a way to make all-solid-state batteries safer and more powerful using inexpensive materials. Instead of adding costly metals, they redesigned the battery's internal structure to help lithium ions move faster. ...

Stanford researchers have developed an AI that can predict future disease risk using data from just one night of sleep. The system analyzes detailed physiological signals, looking for hidden patterns across the brain, heart, and breathing. It ...
