Scientists have pulled back the curtain on one of the most extreme solar regions seen in decades, tracking it almost nonstop for three months as it unleashed powerful space weather. By combining views from two spacecraft—one near Earth and one orbiting the Sun—researchers followed a massive active region as it grew, twisted, and ultimately triggered […]

At extreme pressures and temperatures, water becomes superionic — a solid that behaves partly like a liquid and conducts electricity. This unusual form is believed to shape the magnetic fields of Uranus and Neptune and may be the most common type of water in the solar system. New high-precision experiments show its atomic structure is

Florida State University scientists have engineered a new crystal that forces atomic magnets to swirl into complex, repeating patterns. The effect comes from mixing two nearly identical compounds whose mismatched structures create magnetic tension at the atomic level. These swirling “skyrmion-like” textures are prized for their low-energy behavior and stability. The discovery could help drive

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. This raises new questions about how giant stars spread life-essential elements through space. Researchers

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 expected—without any sign of a hidden fourth type. While this closes off a popular theory, it marks a turning point for the

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, researchers found that cosmic acceleration can arise naturally from a more general geometry of spacetime. The result

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 sidesteps long-standing physical limits that have held optical imaging back for decades. The result is wide-field, sub-micron resolution from distances that

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’s James Webb Space Telescope pierced through thick dust to reveal this violent outflow. The process

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 compared the rocks with Moon samples from the Apollo missions, they found a remarkable match. The results

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 ground-based observatories, scientists detected swirling trails of dense gas created as the companion, called Siwarha, moves through Betelgeuse’s outer layers.
