Visible light image of the circumstellar disk around the nearby young star AU Mic discovered with the University of Hawaii 2.2-meter (88-inch) telescope. The disk is seen edge-on, revealed by starlight scattering off of small dust grains. The outer extent is about 210 astronomical units (20 billion miles). The bright light from the star is blocked by an opaque mask and its supporting crosshairs, allowing detection of the very faint disk. Analysis of the radiation from AU Mic shows that the inner disk is cleared of material, indirect evidence for newly formed planets in the inner regions.
