JWST Sees the Same Supernova Three Times in an Epic Gravitational Lens

Dark Energy Camera in Chile captures the glowing remains of first-ever documented supernova — white-dwarf star that exploded more than 1800 years ago was witnessed by Chinese astronomers, in the year 185 CE

Astronomers catch rare glimpse of oldest known supernova, which dates back to Year 185

Astronomers find a star that survived going supernova after colliding with another star. “I’ve worked on supernova remnants for 30 years and I’ve never seen anything like this,” said Robert Fesen, lead author of the study.
