Data collected using multiple NSF NOIRLab facilities reveal a gamma-ray burst that lasted more than seven hours and ...

Gamma-ray bursts (GRBs) are among the most powerful explosions in the universe, second only to the Big Bang. The majority of ...

A supernova from the early universe looks unexpectedly familiar, challenging ideas about how the first massive stars lived ...

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 ...

The collision of two lightning-bolts-in-the-making spawned an exceedingly brief but extremely energetic flash of gamma rays. This first-of-its-kind observation may help explain an origin of some of ...

Astronomers have performed very long baseline interferometry (VLBI) observations of a gamma-ray loud blazar known as TXS 2013+370. The observations, posted November 19 on the arXiv preprint server, ...

Nearly a century after astronomers first proposed dark matter to explain the strange motions of galaxies, scientists may finally be catching a glimpse of it. A University of Tokyo researcher analyzing ...

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 ...

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 ...

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, ...

Astronomers using the James Webb Space Telescope report that a powerful gamma-ray burst detected in March may have been ...
