A composite view of spiral galaxy NGC 1637 from the JWST and Hubble telescopes reveals the site of the progenitor star that became SN 2025pht. Insets show a red supergiant star that was invisible to Hubble before its explosion but detected by JWST; Hubble’s July 2025 image captures the brilliant aftermath of the supernova.

JWST spots dust-cloaked 'red supergiant' star just before it went supernova

By Sharmila Kuthunur published

Astronomers using JWST have captured the clearest view yet of a doomed red supergiant star just before it exploded, solving a decades-old mystery about why such stars rarely appear to go supernova.
