The brightest-ever lensed superluminous supernova, SN 2025wny, signals a revolution in #Astronomy & Astrophotography
For most of human history, supernovae were rare naked-eye events. Today, modern surveys find them across the Universe, and gravitational lensing (where foreground mass bends distant light) now lets us see the same supernova multiple times with delayed “replays.”
SN 2025wny is the first superluminous supernova ever seen as multiple images, discovered in 2025. Because each image travels a different cosmic path, their brightness and timing differences allow scientists to measure cosmic distances and directly infer the Universe’s expansion rate, a method called time-delay cosmography.
Its biggest implication? 🔭
With the Vera C. Rubin Observatory about to image ~20 billion galaxies repeatedly, astronomers expect thousands of multiply-lensed supernovae in the next decade enabling precision cosmology and dramatically sharpening measurements of the Hubble tension, dark energy, and the fate of the Universe.
👉 SN 2025wny proves we already have the tools to start this revolution, even from the ground
