Musca (Latin for Fly) is one of the minor southern constellations. It contains the soft X-ray transient Nova Muscae 1991 which is a binary star, where one of the stars is a black hole. During the 1991 outburst, radiation produced by positron annihilation was detected from Nova Muscae.

History

Since Musca was introduced in the 17th century, by Johann Bayer, and lies near the southern pole, it was not known to classical or early cultures, and so they produced no mythology concerning it.
