The Gaia telescope has created a new 3D map of the Milky Way, charting the locations of 44 million stars. This map reveals previously hidden star-forming regions and identifies 87 rare, massive O-type stars, whose radiation ionizes hydrogen gas, creating visible HII regions. The Gaia data allows for new perspectives on these stellar nurseries, including nebulae like Gum, North American, and California, with an accompanying video offering a 3D tour.
