NASA is celebrating the holiday season with photographs of the remnants of a supernova star captured by the James Webb space Telescope. The star, named Cassiopeia A (Cas A), shines brightly from roughly 11,000 light-years from Earth, making it look like a decoration better suited for a Christmas tree than in the atmosphere. The images show the inner shell of the star's dust, looking like campfire smoke and giving off bright orange and red hues, but it's the Near-Infrared Camera (NIRCam) that shows the remnants of Cas A reflecting the holiday spirit.
