Zooming in on the globular star cluster Messier 4

This video starts with a broad view of the spectacular central parts of the Milky Way. We close in on the constellation of Scorpius (The Scorpion). Close to its brightest star, Antares, lies the globular star cluster Messier 4, one of the closest of these rich stellar systems to the Earth. The final detailed views of the cluster come from the Wide Field Imager attached to the MPG/ESO 2.2-metre telescope at ESO’s La Silla Observatory in Chile followed by a close up of the central region from the NASA/ESA Hubble Space Telescope.
