Astronomers may have found an exciting new clue about dark energy—the mysterious force driving the universe’s accelerating expansion. They discovered an extraordinarily bright supernova from more than ...

Astronomers have discovered a strange new signal coming from an exploding star — a “chirp” that speeds up over time, similar to the signals seen when black holes collide. The unusual pattern appeared ...

WASHINGTON — A supernova — the explosion marking the end of a massive star's life — is one of the brightest cosmic events, usually about a billion times more luminous than the sun. But some — a small ...

Oscillations in the brightness of a ‘superluminous’ supernova reveal it to be powered by a magnetized neutron star that distorts the orbit of surrounding gas. Superluminous supernovae are often more ...

Astronomers have strengthened long-standing predictions that massive runaway stars could have originated in binary pairs, and were dramatically ejected into space when their companion stars underwent ...
