This first-of-its kind project from the European Space Agency’s (ESA) Gaia mission encompasses over 44 million stars, massive plumes of ionized dust, and regions of immense cosmic energy. In this case, “extinction” refers to the amount of light that is blocked by all that cosmic dust. Once they measured the star’s extinction, the team then rendered those dusty regions into a 3D map which they could chart for ionized hydrogen gas. In addition to 44 million “ordinary” stellar objects, the new map contains 87 O-type stars. The new map features detailed views of the California Nebula, North American Nebula, Gum Nebula, and the Orion-Eridanus superbubble, but it won’t end there.
