Remember SN 2006gy, the brightest supernova ever? It’s back—sort of! Astronomers just spotted its 'light echo,' where the original explosion’s light bounces off cosmic dust, making it look like the supernova is happening all over again. This is a huge deal because today’s tech lets scientists study it in way more detail than in 2006. Basically, we’re getting a cosmic replay of the universe’s wildest fireworks show! #Science #Supernova #SpaceNews
