A bright flash of gamma rays from the constellation Boötes that lasted nearly one minute came from a kilonova, as we described in a new paper. This finding challenges what astronomers know about some ...

A Japanese team has conducted a pioneering study on terrestrial gamma-ray flashes (TGFs). These events, although brief, release phenomenal energy at the heart of thunderstorms. Their precise mechanism ...

A mysterious, high-energy glow from gamma-rays in the Milky Way's center is reigniting the debate: dark matter or a hidden ...

The birth of a gamma-ray burst (GRB) is a stellar event. These incredibly violent blasts are the most energetic explosions in the universe. In just one second, a GRB can release more energy than our ...

A tremendous cosmic explosion 2.4 billion light years away temporarily changed the electric field in Earth’s ionosphere (the electrically-charged upper layer of our atmosphere that helps shield life ...

A strange blast of radiation from space may upend how we categorise such flashes, called gamma ray bursts (GRBs). It seems to come from a black hole forming surprisingly slowly after two stars merge, ...

Scientists are taking a closer look at the afterglow left by the brightest gamma-ray burst ever recorded, and what they see doesn't fit with any theoretical models. When you purchase through links on ...
