SN 1987A

(rare supernova in February 1987 visible by the naked eye)

SN 1987A is a 1987 Supernova (SN) in the Large Magellanic Cloud (LMC), about 168000 light-years away, whose light reached Earth on February 23, 1987. Its maximum Apparent Magnitude (m) was 3 in May 1987. It has been much studied since.

It is considered a Core Collapse Supernova and the remnants are studied to figure out the workings of them. The remnant has much more circular symmetry than spherical, suggesting the progenitor star's spin was a factor.
