View larger. | In the 2016 image on the left, you see 3 images of one supernova (inside circles). The supernova appears triple due to gravitational lensing, whereby space curves around a massive object lying between us and the supernova. The supernova’s light splits as it travels along this curved space. Now look inside the circles in the 2019 image. The 3 supernova images are gone. That’s not surprising. But now astronomers predict a rerun of a supernova blast in the year 2037. The predicted location of that 4th image is highlighted by the yellow circle at top left.

Rerun of a supernova blast
HubbleSite said on September 13, 2021, that astronomers expect a rerun of a faraway supernova. Researchers have seen multiple images of this supernova already, as the light of this distant blast has traveled for 10 billion years to reach our eyes. Now, astronomers say, they expect to see the supernova again in the year 2037. Will it appear to the eye? No. But it’ll appear to all of us thanks to telescopes and advanced imaging. And it’ll appear thanks to the phenomenon of curved space, which was ...
