Either tidal forces or ram-pressure stripping likely created the long cloud of gas that accompanies these objects, their namesake "stream".
Either tidal forces or ram-pressure stripping likely created the long cloud of gas that accompanies these objects, their namesake "stream". The clusters Hodge 301 and R136 are found in an H(II) region in one of them called the Tarantula Nebula, which itself once contained a blue supergiant that became Supernova 1987A. They can be found in the constellations (*) Tucana and Dorado. Henrietta Leavitt's study of period-luminosity relations used Cepheid variables found in these bodies, which are visible from the southern hemisphere. For 10 points, identify these two dwarf galaxies which orbit the Milky Way and are named for a Portuguese explorer.
