▪ binary star - A system of two stars which orbit around each other. Binaries are rather common in this galaxy, apparently. In fact, multiple star systems with as many as six members are known. ▪ black hole - What astronomers are asked most often to explain. We now actually know of a number of different types of black holes. The first discovered is merely the collapsed remnant of a massive star which ended its life in a spectacular supernova detonation. There are also supermassive black holes which, as the name implies, have millions of times the mass of a single star. They are thought to lurk in the heart of just about every large galaxy in this universe. ▪ bolide - An especially bright meteor or shooting star. Bolides are often observed to explode in mid-flight.
