This video, showing a supernova explosion in the Centaurus A galaxy, was created by Judy Schmidt using data from the Hubble Space Telescope. The blueish ring that expands outwards following the blast is a light echo produced by light reflecting off cosmic dust and reaching the telescope with a delay relative to the distance from the source. ⁠ ⁠ (📹 NASA/ESA/B.
