NASA’s powerful James Webb Telescope has returned a new image of an exploding supernova star, giving scientists never-before-seen details, the space agency confirmed Friday.

The detailed photo provides greater insight into the Cassiopeia A supernova, which exploded 340 years ago, the youngest known remnant from such an explosion in our Milky Way Galaxy, NASA said in a statement.

The image, itself, comes from the telescope’s Mid-Infrared Instrument, which provides greater detail than previous infrared imaging. That image is then translated into visible-light wavelengths.
