An international team of astrophysicists from China and Italy has discovered a potential link between gravitational waves and ...

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 ...

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 ...

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 ...

Astronomers have detected a gamma-ray burst (GRB) like none other. GRB 250702B was longer than any ever observed and repeated ...

The collision of two lightning-bolts-in-the-making spawned an exceedingly brief but extremely energetic flash of gamma rays. This first-of-its-kind observation may help explain an origin of some of ...

In 2022, astronomers discovered the brightest gamma-ray burst (GRB) of all time. Now, astronomers confirm that a 'normal' supernova, the telltale sign of a stellar collapse, accompanied the GRB. The ...

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 ...

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