Gamma-ray bursts (GRBs) rank among the most powerful explosions in the universe, releasing immense energy in intense flashes ...

Joseph Shavit The absence of a signal could itself be a signal. This is the idea behind a new study published in the Journal ...

A dark matter signal that appears in one place but not another might look like a contradiction. This new study argues it may ...

When a massive star collapses or two neutron stars collide billions of light-years away, the explosion can unleash a brief, ...

Astronomers have spotted a bizarre cosmic explosion that refuses to play by the rules—and it’s leaving scientists scrambling for answers. GRB 250702B, detected by NASA’s James Webb Space Telescope and ...

Astronomers have finally identified the source of unusual X-rays from the bright star gamma-Cas, resolving a decades-long ...

A mysterious glow of gamma rays at the center of the Milky Way has long hinted at dark matter, but the lack of similar ...

Dark matter may consist of two particles, explaining why only the Milky Way shows a strange gamma-ray signal while smaller ...

The Milky Way’s center glows with an unexplained surplus of gamma rays. Smaller galaxies orbiting nearby do not. That ...

A new study suggests that failing to detect dark matter signals in some galaxies may not contradict evidence seen in our own.

Gamma-ray bursts are a relatively new field in space science. The first was discovered in the late 1960s, and in the nearly six decades since, there’s never been a discovery quite like this. It may ...

GRB 250702B is 'the longest gamma-ray burst that astronomers have ever observed,' according to NOIRLab. See imagery of the ...
