This constellation contains the object BL Lacertae. BL Lacertae is a blazar, which is a quasar with one of its jets oriented so that it points directly toward Earth. A quasar is a unique type of galaxy that has a supermassive black hole spinning at its center. As matter falls in toward the black hole due to gravitational attraction, it is then propelled outward in jets that are caused by a magnetic field generated by the black hole's spin.
