Astronomers have spotted the longest gamma-ray burst ever seen, a cosmic explosion that lasted seven hours — and they determined it could be the work of a black hole destroying a star. Gamma-ray ...

For over a decade, the Fermi Gamma-Ray Space Telescope has mapped a mysterious excess of gamma-ray light in the inner regions of the Milky Way. This unusual glow spans thousands of light-years and ...

Here’s what you’ll learn when you read this story: For nearly a century, scientists have been searching for direct evidence of dark matter—one of the key missing pieces of our theoretical ...

Astronomers are trying to understand what caused a series of gamma ray bursts, or GRBs — the most powerful explosions in the universe. These energetic bursts are typically unleashed by the incendiary ...

Researchers may have identified what could be a compelling clue in the ongoing hunt to prove the existence of dark matter. A mysterious diffuse glow of gamma rays near the center of the Milky Way has ...

Stephen has degrees in science (Physics major) and arts (English Literature and the History and Philosophy of Science), as well as a Graduate Diploma in Science Communication. Stephen has degrees in ...

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 ...

The study of gamma-ray emission from globular clusters (GCs) and their resident millisecond pulsars (MSPs) presents a compelling window into high-energy astrophysics. GCs are densely populated, ...

For decades, astronomers have been puzzled by a mysterious glow of gamma rays emanating from near the center of the Milky Way. Two theories have emerged: either the light was the result of dark matter ...

In the early 1930s, Swiss astronomer Fritz Zwicky observed galaxies in space moving faster than their mass should allow, prompting him to infer the presence of some invisible scaffolding—dark ...

A team of astronomers have observed an explosion in the universe unlike any ever witnessed before. The gamma-ray bursts from outside the Milky Way galaxy repeated several times over the course of a ...
