Brief flashes of millimeter-wave light seen by the South Pole Telescope reveal magnetic activity in compact white dwarf systems close to the Galactic center, showing that these small stars can release energy in unexpected ways. The center of the Milky...

High-resolution images show swirling magnetic structures covering much of the Sun’s surface, suggesting pervasive solar magnetism. A team of solar researchers has identified a previously unseen layer of activity on the Sun, documenting extensive...

Astronomers have detected a solar-like eruption near a supermassive black hole, revealing how magnetic energy drives powerful winds in deep space. Astronomers have captured evidence of a violent magnetic eruption occurring near a supermassive black...

A new survey has identified 529 quiet, mature K dwarf “Goldilocks stars” near the Sun, offering the most stable radiation environments known and creating an unprecedented list of prime targets in the search for habitable exoplanets. For generations,...

A record-breaking gamma-ray burst from 2 billion light-years away has left a rare, measurable electrical signature in Earth’s upper atmosphere. A staggering burst of radiation from an exploding star, located nearly 2 billion light-years away, has...

Scientists reveal how changes in space weather could make the aurora borealis more visible than ever. Discover what’s behind these stunning sky shows. The aurora borealis, also known as the northern lights, is a dazzling display of colored lights that...

New research suggests powerful magnetic fields can tear apart and trap giant stellar eruptions, preventing plasma from escaping into space. The mystery of why astronomers observe frequent, intense flares on highly active stars while rarely detecting...
