Located in the constellation Scorpius is an
8th magnitude globular cluster called M80. This cluster has a
diameter of around 90 light-years and is located roughly 36,000
light-years from the Earth. This cluster was the site of a nova
in 1860, which completely changed its appearance for several
days. A second nova occurred in 1938, but was only observed
photographically. Visually, this globular cluster resembles a
comet. A large telescope is required to reveal the cluster's
individual stars.
