Cassiopeia A

Damn. The wonder of the universe, that a single star can create such powerful beauty.

Webb is having a * stellar * week. 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 from Earth’s perspective.. Cas A is the youngest known remnant from an exploding, massive star in our galaxy, which makes it a unique opportunity to learn more about how such supernovae occur. https://www.nasa.gov/feature/goddard/2023/webb-reveals-never-before-seen-details-in-cassiopeia-a
