For the first time, scientists have witnessed the inner workings of a dying star as it exploded, offering an unprecedented glimpse into the intricate process of stellar evolution. While cosmic ...

Astronomers have for the first time seen the birth of a magnetar—a highly magnetized, spinning neutron star—and confirmed that it's the power source behind some of the brightest exploding stars in the ...

Some stars in our galaxy, known as hypervelocity stars, move much faster than most other stars in the Milky Way. In fact, they are traveling so fast that our galaxy’s gravity can’t hold onto them and ...

A team of astronomers believe they’ve witnessed a star split in half before merging back together again, triggering an ungodly double explosion that’s sending seismic ripples through both the ...

Astronomers have discovered that the birth of neutron stars with magnetic fields trillions of times stronger than Earth's magnetosphere is the "magic trick" behind superbright supernovas.
