Description
The explosion of a star is a dramatic event, but the remains that the star leaves behind can be even more dramatic. A new mid-infrared image from NASA’s James Webb Space Telescope provides one stunning example. It shows the supernova remnant Cassiopeia A (Cas A), created by a stellar explosion 340 years ago. The image displays vivid colors and intricate structures begging to be examined more closely. Cas A is the youngest known remnant from an exploding, massive star in our galaxy, offering astronomers an opportunity to perform stellar forensics to understand the star’s death.
