A super-small gamma-ray burst defies astronomers’ anticipations

A incredibly small gamma-ray burst has astronomers rethinking what triggers these celestial cataclysms.

The Fermi Gamma-ray Place Telescope detected a solitary-next-extended blast of gamma rays, dubbed GRB 200826A, in August 2020. These kinds of fleeting gamma-ray bursts, or GRBs, are typically considered to originate from neutron star smashups (SN: 10/16/17). But a nearer glance at the burst unveiled that it arrived from the implosion of a substantial star’s main.

In this circumstance, the core of a star collapses into a compact object, such as a black gap, that powers substantial-pace particle jets. People jets punch by way of
