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 Perseus-Taurus constellations.cite-ref-1[1] cite-ref-0-2-0[2] A team from the Harvard Smithsonian Center for Astrophysics led by Catherine Zucker and Shmuel Bialy discovered the structure in 2021.cite-ref-0-2-1[2] Scientists believe that it appeared following the explosions of ancient supernovae.cite-ref-3[3]cite-ref-4[4]cite-ref-5[5] Molecular clouds surround the sphere-shape cavity.cite-ref-6[6]
