Zoom through the Milky Way's stellar nurseries in this super-detailed 3D map (video)

September 22, 2025
Astronomers have unveiled the most detailed 3D map ever made of stellar nurseries in our Milky Way galaxy. Using data from the European Space Agency’s (ESA) Gaia space telescope, astronomers constructed the first-ever 3D view of star-forming regions that are otherwise hidden by thick clouds of gas and dust, making it difficult to measure their true distances. A new video of the 3D stellar…
