NASA’s Chandra Reveals Star’s Inner Conflict Before Explosion
NASA’s Chandra Reveals Star’s Inner Conflict Before Explosion NASA’s Chandra X-ray Observatory has revealed that a star called Cassiopeia A (Cas A) underwent a violent rearrangement of its interior just hours before it exploded as a supernova. The study found that part of an inner layer rich in silicon traveled outwards and broke into a […]

Seeing the Cygnus Loop in a New Way
Seeing the Cygnus Loop in a New Way NASA’s Chandra X-ray Observatory has created a 3D model of the Cygnus Loop, a supernova remnant that provides insights into the explosive death of a massive star. The 3D model allows people to explore and print examples of stars in the early and end stages of their […]
