The main image at left shows a view of spiral galaxy NGC 1637 from NASA’s James Webb Space Telescope and Hubble Space Telescope. Hubble’s shorter-wavelength data is represented in blue and green, while Webb’s longer-wavelength data is represented in green and red. Panels at the right show a detailed view of a red supergiant star before and after it exploded. Before exploding, it is not visible to Hubble, only to Webb. Hubble shows the glowing aftermath in July 2025.
