Ian Shelton discovered SN1987A, which occurred inside one of these bodies, which are located in Dorado and Tucana.
In 2007, Gurtina Besla calculated that these objects were on their first and only parabolic orbit. They contain blue globulars, such as NGC1978, and one of them is located near in the sky to the globular cluster 47 Tucanae. A nearby "stream" that shares a name with these objects is either a tidal tail or a cloud of ram pressure-stripped gas. Twenty-four neutrinos were detected from an core collapse in one of them, which occurred at the star Sanduleak [sahn-doo-LAY-ahk]. De Lacaille discovered that an H-II [H-two] region in the same one of these objects possesses nebulosity.  That region is now known as the Tarantula Nebula. Ian Shelton discovered SN1987A, which occurred inside one of these bodies, which are located in Dorado and Tucana. Objects within them were used to calibrate standard distance candles by Henrietta Leavitt. For 10 points, name these astronomical objects visible to southern observers, two of the Milky Way's satellite galaxies.
