Researchers from Nanjing University, led by Xiao-Fei Dong, have made a significant contribution to the field of physics by conducting a comparative analysis of two samples of long gamma-ray bursts (LGRBs). This study, published in The Astrophysical Journal, reveals intriguing differences between LGRBs with and without supernova (SN) associations, shedding

Dark matter
Researchers studying a diffuse glow of gamma rays near the center of the Milky Way galaxy have made a significant step towards confirming the existence of dark matter, a mysterious component thought to make up over a quarter of the cosmos. The cosmic landscape is dominated by ordinary matter, which

A recent study on the preprint server arXiv has shed light on a unique gamma-ray burst (GRB) event that is challenging our understanding of how stars die. GRB 250702B, detected by NASA's Fermi telescope on July 2, 2025, is the longest gamma-ray burst ever recorded, lasting for a

A team of astronomers has observed an explosion in the universe like no other, defying current understanding of gamma-ray bursts. The gamma-ray bursts, originating from outside the Milky Way galaxy, repeated several times over the course of a day. This phenomenon, known as GRB 250702B, was spotted through the European
Gamma rays
Astronomers have observed a gamma-ray burst (GRB) that defies decades of understanding about these cosmic explosions. A recent study published in The Astrophysical Journal Letters reveals that this GRB exhibited behavior never seen before: repeated and potentially periodic bursts of gamma-ray energy from the same source. This observation suggests that

A remarkable event has been captured by researchers in Japan, where a lightning collision produced a gamma-ray burst, a high-energy emission typically observed from cosmic phenomena. The study published in Science Advances outlines how a sophisticated array of sensors recorded a terrestrial gamma-ray flash (TGF) triggered by a lightning collision
