Interactive 3D view of the Orion complex with dust and stars. Molecular cloud spines for Orion A, Orion B, and Orion \(\lambda\) are shown in green, blue, and purple respectively. The purple sphere indicates OBP-B1 Sphere, the bubble likely produced by OBP-B1. Major ionizing stars in the region are shown in teal. The orange point indicates the expansion center of OBP-B1, and the orange vector indicates the direction to the Sun. Aligning the orange vector with the orange point (and the molecular clouds in the background) shows the view from the Sun. Stars of OBP-B1 and their velocities are shown with blue vectors and clusters identified in Großschedl et al. (2021) are shown with purple vectors. The Orion Shell is shown in white.
