![]() ![]() After combing through all of this data, astronomers can now characterize just how bright it was and better understand its scientific impact. The burst triggered detectors on numerous spacecraft, and observatories around the globe followed up. The closer to head-on we view one of these jets, the brighter it appears.ĭownload high-resolution video and images from NASA’s Scientific Visualization Studio.Ĭredit: NASA’s Goddard Space Flight Center They then plow into material surrounding the doomed star and produce a multiwavelength afterglow that gradually fades away. These jets pierce through the star, emitting X-rays and gamma rays (magenta) as they stream into space. The black hole then drives jets of particles that drill all the way through the collapsing star at nearly the speed of light. Astronomers think most occur when the core of a massive star runs out of nuclear fuel, collapses under its own weight, and forms a black hole, as illustrated in this animation. Gamma-ray bursts are the most luminous explosions in the cosmos.
