It was in 1901 — 112 long years ago — that the star GK Persei first exploded in a spectacular nova that reached a magnitude of 0.2, making it the brightest until Nova Aquilae 1918. But ever since, the blown-up star has gradually been expanding and putting out bursts of magnitude that remain visible to telescopes. By splicing together images covering the star’s over 58 years, researchers have been able to create a 3D representation of the event, which you’ll see in the video below. Of course you’re also treated to the photos themselves, captured by the Isaac Newton Telescope and the Nordic Optical Telescope in Spain. Even at 1,300 light years from Earth, the explosion is a rather wondrous sight.
