A gamma-ray burst (GRB) that has confounded astronomers is one of the brightest cosmic light shows in the past 20 years.

On July 2, 2025, NASA's Fermi Gamma-ray Burst Monitor (Fermi-GBM) captured around three hours' worth of signals that appeared to come from the same source. When scientists compiled this data with ...

The video explains cosmic phenomena such as rogue black holes, gamma-ray bursts, magnetars, vacuum decay and collapsing magnetic fields. It looks at why astronomers study them as possible risks to ...

Astronomers are trying to understand what caused a series of gamma ray bursts, or GRBs — the most powerful explosions in the universe. These energetic bursts are typically unleashed by the incendiary ...

A cosmic explosion detected on July 4, 2025, began with a 0.4-second gamma-ray burst and then continued glowing in softer X-rays for nearly 10 minutes. Astronomers say the unusual signal may have come ...

COLUMBIA, S.C. (WIS) - Gamma-ray bursts are a relatively new discovery in space science. The first burst was discovered in the late 1960s. You might be wondering ...

Scientists have detected an incredibly powerful burst of gamma radiation that repeated several times over a single day … and they can’t quite explain it. EarthSky’s Will Triggs has the story in this ...

Astronomers have observed the longest-lasting central engine activity ever recorded from a gamma-ray burst. The burst occurred at a redshift of 0.8577, and the activity lasted about 27 days in the ...

Astronomers have been poring over a flood of data from NASA satellites and other facilities. They’re trying to work out what was responsible for an extraordinary cosmic outburst discovered on July 2, ...

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 ...
