A small portion of the Sculptor dwarf galaxy, a satellite galaxy of the Milky Way, as observed by the NASA/ESA Hubble Space Telescope.

This image shows one of two different pointings of the telescope that were used in a study combining the Hubble data with observations by ESA's Gaia mission to measure the three-dimensional motions of stars in this galaxy. The study has shed new light on the underlying distribution of invisible dark matter that pervades the galaxy.
