Keck Observatory's New Planet Imager Delivers First Science

A new instrument on the W. M. Keck Observatory in Hawaii has delivered its first images, showing a ring of planet-forming dust around a star and, separately, a cool star-like body, called a brown dwarf, lying near to its companion star.
The device, called the vortex coronagraph, was recently installed inside the Near Infrared Camera 2 (NIRC2), the workhorse infrared imaging camera at Keck. The vortex coronagraph has the potential to image planetary systems and brown dwarfs closer to their host stars than was possible previously
