Particle never before seen on Earth detected; it could come from a primordial black hole and the origin of the universe.

Gamma ray bursts are the most energetic events in the universe. What if one hit Earth?

To avoid Swift being dragged down low enough to hit Earth’s atmosphere, NASA tapped an Arizona-based startup to launch a ...

What if we told you that supernovas aren't the brightest events in the Universe? Gamma-ray bursts are. They shine hundreds of times brighter and only last for several minutes at most. But even a ...

Solar flares send intense bursts of energy and radiation from the Sun’s surface, but could one take out the earth? Solar flares are characterized by intense bursts of energy and radiation from the Sun ...

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 ...

Scientists have detected the most distant supernova ever seen, exploding when the universe was less than a billion years old. The event was first signaled by a gamma-ray burst and later confirmed ...

Astronomers have observed the longest gamma-ray burst — a powerful, extragalactic explosion that lasted more than seven hours. It was so extraordinary that several teams of scientists have been poring ...

This artist’s illustration, which shows a high-speed jet of material being launched from a source that is embedded in a very dusty galaxy, depicts GRB 250702B — the longest gamma-ray burst that ...
