This NASA/ESA Hubble Space Telescope image shows the central region of a globular cluster known as NGC 104 or, more commonly, 47 Tucanae, since it is part of the constellation of Tucana (The Toucan) seen in ultraviolet light. Using the ultraviolet capabilities of Hubbles sharp-eyed Wide Field Camera 3, the astronomers traced populations of white dwarfs with a range of ages and positions. This made it possible, for the first time, to collect a census of young white dwarf stars beginning their migration from the crowded centre of an ancient star cluster to its less populated outskirts.
