The Perseus-Taurus Supershell in Space (IMAGE) Harvard-Smithsonian Center for Astrophysics Caption Astronomers have discovered a giant, spherical cavity within the Milky Way galaxy; its location is depicted on the right. A zoomed in view of the cavity (left) shows the Perseus and Taurus molecular clouds in blue and red, respectively. Though they appear to sit within the cavity and touch, new 3D images of the clouds show they border the cavity and are quite a distance apart. This image was produced in glue using the WorldWide Telescope. Credit Alyssa Goodman/Center for Astrophysics | Harvard & Smithsonian. Usage Restrictions Credit must be given to the creator.
