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 ...

Gold was not born on our planet Earth; it was forged in a violent ‘cosmic forge’ far beyond our solar system. This means that ...

Yet what we can see with our eyes, or even with powerful telescopes, when these stars die, is only a tiny fraction of the story. Because most of the energy from a supernova is car ...

For decades, scientists have tried to measure how fast the universe is expanding. This expansion rate is known as the Hubble ...

A team of physicists at the University of Massachusetts Amherst recently hypothesized that the event that occurred in 2023, when a subatomic particle called a neutrino crashed into Earth with such ...

Sixteen years ago, theoretical astrophysicists at UC Berkeley and elsewhere proposed that highly magnetized, spinning neutron stars — magnetars — were the power source behind some superluminous ...
