This supern" - 2119967728618224952

What remains after a star explodes 💥 ? A brightly glowing field of debris, expanding outward into space.⁣ ⁣ This supernova remnant, Cassiopeia A or Cas A, was imaged by our Chandra X-ray Observatory (@nasachandraxray). It's located about 11,000 light years from Earth and was also featured in Chandra's "first light" image at the start of the mission in 1999. This recent study of Cas A adds to a long collection of Chandra discoveries over the course of the telescope’s 20 years. In addition to finding the central neutron star, Chandra data have revealed the distribution of elements essential for life ejected by the explosion, clues about the details of how the star exploded, and much more.⁣ ⁣ Image credit: X-ray: NASA/CXC/RIKEN/T.
