Thanks to the gravitational lensing caused by a massive galaxy cluster and high-resolution images from the James Webb Space Telescope (JWST), astronomers discovered an exploding star when the universe was 4.9 billion years old. The discovery paper, posted to the arXiv preprint server on Oct. 23, presents a prediction for when the rest of the distorted images of SN Ares will arrive.
