(Phys.org)—A team of astronomers has found a hydrogen-poor superluminous supernova with exceptional properties. According to a research paper published online on May 17, on the arXiv pre-print server, the cosmic explosion, ...
A giant star that exploded 30 million years ago in a galaxy near Earth had a radius prior to going supernova that was 200 times larger than our sun, according to astrophysicists at Southern Methodist University, Dallas.
