How Hubble captured the same supernova exploding four times in one image
Dr. Brian Welch explains how the Hubble Space Telescope captured a rare cosmic event where a single supernova, known as Refsdal, appeared to explode four separate times. This video highlights the power of gravitational lensing and Hubble's vital role in uncovering the universe's deepest mysteries.
The phenomenon, known as gravitational lensing, occurs when a massive galaxy cluster bends the light of a distant object. In this specific case, the cluster's gravity acted like a cosmic magnifying glass, creating multiple images of the Refsdal supernova.
By observing these repeated explosions, scientists gain unique insights into the structure of the universe. The video serves as an exploration of how Hubble continues to provide the data necessary to study such complex celestial mechanics.
