Kind: research · Impact: low

## In brief

- Astronomers used gravitational lensing from a massive galaxy cluster and JWST high-resolution images to discover an exploding star when the universe was 4.9 billion years old.
- The discovery paper was posted to the arXiv preprint server.
- The lensing could show the same supernova two more times in roughly 70 years, according to the source.

## Why it matters

Lensed supernovae that reappear at different times allow astronomers to measure the expansion of the universe and test lensing models, so the prediction is a concrete test for future observations.
