A Vanished Supernova Will Reappear in 16 Years - Gizmodo
The supernova was seen with the Hubble Space Telescope by a team of French, American, and Danish researchers.Analyzing Hubble infrared data from a particular portion of space, the team realized that three light sources seen in 2016 had disappeared by 2019.
As it turned out, all three of those light sources came from a single explosion, but the light took different routes to reach Hubble’s lens.
Excitingly, another spot of light from the burst is expected to arrive at Earth in 2037, give or take a couple years, based on the team’s calculations.
(“Like a baby photo and two photos of an angsty teenage [supernova],†Rodney said.) Those flashes were gone by 2019, but the team calculated that more light from that ancient explosion will arrive in about 16 years.
