In 1991, a nova erupted on the western edge of the constellation, designated as N 1991, which briefly became one of the brightest sources of X-ray radiation in the sky. It is believed to be a close binary star, with one component orbiting around a black hole, which can trigger processes leading to intense X-ray emission.
