Illustration. When a star much more massive than the Sun runs out of fuel, its core suddenly collapses and forms a black hole. As matter swirls toward the black hole, some of it escapes in the form of two powerful jets that rush outward at almost the speed of light in opposite directions. Normally jets from collapsing stars produce gamma rays for many seconds to minutes. Astronomers think the jets from GRB 200826A were weak and shut down quickly, producing a quick burst (magenta) lasting just 0.65 second.
