Heart of the Local Void. The deepest parts of the void are mapped by surfaces of density −1.1 (black) and −0.7 (dark gray). Local minima are located by red dots and given names. The contours in shades of light gray and red illustrate surrounding high-density structures. The Milky Way is at the origin of the red, green, and blue directional arrows. The same scene is shown from multiple vantage points. The reference viewing direction in the upper left panel is from positive values of all 3 coordinates (video frame time: 02:01). At upper right, the scene has been rotated around to almost in from the negative SGY axis (02:25). Then at lower left the view is in from very near to the positive SGZ axis. In this latter case, a foreground clip at SGZ = +3000 km s−1 has removed the Arch to give an unrestricted view of the void (02:32). In the lower right panel, the Local Void contours are shown alone, looking in from positive SGY (02:42). The animation is at 640 × 368 pixel resolution, runs for 10:56 m, and includes on-screen captions of individual scenes. A full resolution version is available on Vimeo (https://vimeo.com/326346346/35088b5dd8).
