E0102-72.3 (SNR B0102-72.3), short for 1E 0102.2-7219, is the remnant of a supernova that exploded in the Small Magellanic Cloud, a neighbouring galaxy of the Milky Way. The supernova was caused when a star much more massive than the Sun collapsed under its own gravity. The explosion would have been visible from the Southern Hemisphere of the Earth over 1000 years ago.
