The Perseus-Taurus Shell (also shortened to the Per-Tau shell) is a near-spherical cavity in the interstellar medium, 500 light-years wide, located in the Milky Way in the direction of the Perseus and Taurus constellations.[1][2] A team from the Harvard Smithsonian Center for Astrophysics led by Catherine Zucker and Shmuel Bialy discovered the structure in 2021.[2] Scientists believe that it appeared following the explosions of ancient supernovae.[3][4][5] Molecular clouds surround the sphere-shape cavity.[6]
