They discovered that the host galaxy is incredibly massive — weighing in at over 40 billion times the mass of our Sun — and deeply obscured. The James Webb Space Telescope, which can peer through gas ...

The KM3NeT Collaboration, operating a partially built neutrino detector on the Mediterranean seafloor off the coast of Sicily, has recorded a cosmic neutrino with an estimated energy of about 220 PeV, ...

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.

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 ...

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

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

It's commonly believed that there's no sound in space, but that's far from the case. For instance, sonifications from NASA have allowed us to hear the sounds of a black hole, and, in 2025, astronomers ...

More information about a mysterious, energetic burst, formally known as a gamma-ray burst (GRB), spotted in space 13 billion light-years away from Earth, has been unveiled. The first sighting of this ...

Gamma-ray bursts (GRBs) are among the most powerful explosions in the universe, second only to the Big Bang. The majority of these bursts are observed to flash and fade within a few seconds to minutes ...

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 ...

A space explosion detected this summer burned for days on end, making it the longest and most unusual gamma-ray burst ever seen. Gamma-ray bursts are the universe’s most powerful explosions. They ...
