GRB 230906A, a short gamma-ray burst first detected in 2023, points to a faint galaxy embedded within a long stream of torn ...

Astronomers spend careers watching stars collapse and explode, but an eruption spotted in July pushed beyond anything seen before. The event, called GRB 250702B, released high-energy radiation for ...

NASA’s James Webb Space Telescope reveals new clues about a mysterious cosmic explosion that defies expectations.

Although scientists have believed for some time that most gamma-ray bursts are very distant, a Goddard scientist has discovered 100 of them that are quite “local,” within 325 million light years from ...

Astronomers have discovered the brightest fast radio burst ever detected and traced it to a nearby galaxy using a new network of CHIME Outrigger telescopes. The flash, nicknamed RBFLOAT, lasted only a ...

On Sunday, Oct. 9, 2022, a pulse of intense radiation swept through the solar system so exceptional that astronomers quickly dubbed it the BOAT – the brightest of all time. The source was a gamma-ray ...

Lightning is a phenomenon that has fascinated humanity since time immemorial, providing a stark example of the power and unpredictability of the natural world. Although the study of lightning can be ...

When faraway stars explode, they send out flashes of energy called gamma-ray bursts that are bright enough that telescopes back on Earth can detect them. Studying these pulses, which can also come ...

Roughly a year ago, astronomers announced that they had observed an object that shouldn’t exist. Like a pulsar, it emitted regularly timed bursts of radio emissions. But unlike a pulsar, those bursts ...

Scientists had predicted based on theory that shrouded cosmic explosions that go unnoticed can be revealed by their light echoes. Now, astronomers have spotted such an explosion.
