Rather, we found the cocoon is actually something else entirely: gamma rays from the Sagittarius dwarf galaxy, which happens to be behind the southern bubble as seen from the position of Earth.

Dozens of telescopes all over the world are pointing at a patch of sky that gave rise to the most powerful gamma-ray burst ever seen, hoping to shed more light on processes that birth black holes.

A thunderstorm seen in gamma-ray vision is a complex, frenetic lightshow when viewed from above the clouds.

Because the film was stacked like a pancake, the team could track the trajectory of gamma ray particles, and the aparatus’s position in the stratosphere eliminated any would-be ground interference.

An unusual, long-lasting gamma-ray burst challenges theories about how they work In a few seconds, a gamma-ray burst emits as much energy as the Sun will radiate in its entire life ...

Using a combination of telescopes, astronomers have characterized the closest supernova linked to a fast X-ray transient. The ...

Physicists and astronomers have studied gamma rays caused by the Sagittarius Dwarf, a small neighboring galaxy of our Milky Way. They showed that all the observed gamma radiation can be explained ...

Brightest-ever gamma-ray burst (the “BOAT”) continues to puzzle astronomers No evidence of associated supernova, and afterglow radio data contradicts current models.

The ‘Brightest of All Time’ Gamma-Ray Burst Sparks a Supernova Hunt Telescopes around the world are capturing photons from the blast, and researchers anticipate exciting discoveries ahead.

A team of researchers, including UvA physicists and astronomers, has studied gamma rays caused by the Sagittarius Dwarf, a small neighbouring galaxy of our Milky Way. They showed that all the ...

Rather, we found the cocoon is actually something else entirely: gamma rays from the Sagittarius dwarf galaxy, which happens to be behind the southern bubble as seen from the position of Earth.

Schematic showing the Milky Way, the gamma-ray-emitting Fermi Bubbles (pink), and the Sagittarius dwarf galaxy and its tails (yellow/green). From the position of the Sun, we view the Sagittarius ...
