Astronomers have discovered that the birth of neutron stars with magnetic fields trillions of times stronger than Earth's ...

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 ...

Astronomers have identified the first clear evidence of a magnetar forming during a superluminous supernova, offering new insight into some of the brightest explosions in the universe.

Imagine looking up at the night sky and seeing a star suddenly burst into a blaze of light brighter than anything nearby. A flash so bright that it briefly outshines an entire galaxy before fading ...

The night sky appears perfectly still, but the universe is constantly changing in ways the human eye cannot see. By combining decades of astronomical observations, scientists have created remarkable ...

Scientists have detected the most distant supernova ever seen, exploding when the universe was less than a billion years old. The event was first signaled by a gamma-ray burst and later confirmed ...

We could go out with a crunch, and not a bang. Contrary to popular belief, our universe may not be constantly expanding after all. A groundbreaking study by South Korean researchers suggests that dark ...

The universe’s expansion might not be accelerating but slowing down, a new study suggests. If confirmed, the finding would upend decades of established astronomical assumptions and rewrite our ...

Last year, our most detailed map of the universe yet suggested our understanding of dark energy has been wrong for decades.
