This deep dataset from Chandra of the remains of a supernova known as 30 Doradus B (30 Dor B) reveals evidence for more than one supernova explosion in the history of this remnant.
Unusual structures in the Chandra data cannot be explained by a single explosion.
These images of 30 Dor B also show optical data from the Blanco telescope in Chile, and infrared data from Spitzer.
Additional data from Hubble highlights sharp features in the image.Image Credit: X-ray: NASA/CXC/Penn State Univ./L.
