Webb Sees a Supernova Go Off in a Gravitationally Lensed Galaxy – for the Second Time
Webb Sees a Supernova Go Off in a Gravitationally Lensed Galaxy – for the Second Time Nature, in its infinite inventiveness, provides natural astronomical lenses that allow us to see objects beyond the normal reach of our telescopes. They’re called gravitational lenses, and a few years ago, the Hubble Space Telescope took advantage of one of them to spot a supernova explosion in a distant galaxy. Now, the JWST has taken advantage of the same lens and found another supernova in the same galaxy. A gravitational lens is a massive object like a galaxy or galaxy cluster. The object’s mass creates a curvature in space-time.Read More →
