In 1912, Henrietta Leavitt deduced the behavior of Cepheid variables in one of these galaxies. First studied by Sir John Herschel, they are located in the constellations Dorado and Tucana near 160 thousand light-years from earth. A fading 1987 supernova that was the first one viewable without a telescope since 1604 is still visible in one of these galaxies. Only appearing in the far southern sky, FTP, give the common name of these celestial bodies, one large and one small irregular collection of stars, dust and gas, named for a Portuguese navigator.
