Where specialized algorithms fail to classify star-borne pulses, human volunteers with just a little training can step in.

Some ancient texts record what were likely dying stars, faintly visible from Earth. If close enough, these events can disturb telescopes and even damage the ozone layer.

New research may better explain the "string of pearls" around the remnant of a star, shedding light on a longstanding astrophysical mystery.

There are signs that Betelgeuse may be evolving rapidly – meaning a supernova explosion may happen sooner rather than later.

Astronomers have found that mysterious dark energy may originate in black holes.

Gamma-ray bursts occur when a massive star explodes or when two neutron stars merge. A newly discovered burst has puzzled astronomers, as it lasted much longer than astronomers would have expected.

Astronomers have discovered the first dormant black hole outside of the Milky Way. These black holes are not absorbing matter from a nearby star, making them incredibly hard to find.

It’s long been a mystery how black holes form, now astronomers are on the verge of cracking it.

An odd metallic star called LP 40-365 is hurtling out of the Milky Way galaxy at absurd speed, researchers say. It's "shrapnel" from an exploding star.
