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 ...

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 ...

This artist’s concept shows the entire sky in gamma rays with magenta circles illustrating the uncertainty in the direction from which more high-energy gamma rays than average seem to be arriving. In ...

A powerful flash of radiation from a dying star sent astronomers into a flurry of fast-paced activity last week, as they raced to gather data on the explosion’s afterglow. This image, made from data ...

The longest gamma-ray burst ever recorded did not behave like a quick cosmic flash. Instead, it burned across the sky for more than seven hours, forcing astronomers to rethink what powers the universe ...

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 high-energy signal lasting over seven hours, first observed in mid-2025, has drawn intense scrutiny from astrophysicists ...

A bright flash of gamma rays observed March 28 by the Swift satellite may have been the death rattle of a star falling into a massive black hole and being ripped apart, according to a team of ...

Complex lead halides with the perovskite structure has been extensively studied in recent years in terms of radiation hardness. Many researchers found surprisingly high resistance of various ...
