For over 25 years, scientists believed the universe was accelerating due to a mysterious force called dark energy. But a new analysis from Yonsei University is turning that idea upside down. By revisiting Type Ia supernova data with more precise measurements, researchers found clues that today’s expansion rate might be decelerating, not accelerating. If true, dark energy may not be constant — or we may have misunderstood something fundamental about the fabric of spacetime. Sources and expert rea

A new Star Explosion called a supernova has been spotted in the Pinwheel galaxy. I pointed my telescope at the galaxy and found it here. If I compared it to the picture I captured of the galaxy 2 years ago, it's easy to see out stand out. At 21 million light-years away, this is the closest supernova in a decade. I captured this with my Celestron RASA (8-inch) telescope, ZWO ASI533MC color camera, and an Optolong L-Pro filter. #astronomy #cosmos #dark #milkyway #natgeo #nebula #nightsky #outerspa
