In a galaxy far, far away ..... a supernova!3D ModelNoAI
A supernova is the result of a powerful and luminous stellar explosion. The transient event can be the final fate of a massive star or of a white dwarf triggered into runaway nuclear fusion. During the outburst a huge amount of energy is released and the luminosity suddenly increases reaching a peak value that can be comparable to that of an entire galaxy. Then the luminosity fades away over several weeks or months. The model is an artist’s view which illustrates a supernova occurring on the outskirt of a host spiral galaxy. The image used to represent the galaxy shows the spectacular spiral galaxy NGC 3982 (credits: STScI/NASA, ESA) and is composed of exposures taken by the Hubble Space Telescope’s Wide Field Camera 3 (WFC3), the Advanced Camera for Surveys (ACS), and the Wide Field Planetary Camera 2 (WFPC2).
