NASA Telescope Captures Never-Before-Seen Details Of Remnant Of Star That Exploded 340 Years Ago

Cas A is the youngest remnant of a massive star in our galaxy known to mankind. It offers a peek into the supernovae phenomenon and its complexities.

NASA's James Webb Space Telescope recently captured "never-before-seen" detail of Cassiopeia A (Cas A), a remnant of a massive star that exploded some 340 years ago. Taking Instagram, the US space agency shared a stunning image of the exploding supernova. 

"As the youngest known remnant from an exploded, massive star in our galaxy, Cas A offers unique clues into a star's death. By studying Cas A, Webb astronomers may also learn more about the origins and production of cosmic dust - which forms the elements we're made of," the caption of the post read.
