This image shows a combined JWST and Hubble view of spiral galaxy NGC 1637, with the region of interest in the top right. The remaining three panels show a detailed view of a red supergiant star before and after it exploded. The star is not visible in the Hubble image before the explosion, but appears in the JWST image. The July 2025 view from Hubble shows the glowing aftermath of the explosion. Image Credit: NASA, ESA, CSA, STScI, Charles Kilpatrick (Northwestern), Aswin Suresh (Northwestern)

Astronomers working with the JWST, along with help from the Hubble, have found a red supergiant star that eventually exploded as a supernova. The discovery helps solve the 'red supergiant problem' that confounds efforts to understand how these stars serve as progenitors that eventually explode as Type II supernova.
