Summary[edit]

Description
English: Left: This is an image of the star HR 8799 taken by Hubble's Near Infrared Camera and Multi-Object Spectrometer (NICMOS) in 1998. A mask within the camera (coronagraph) blocks most of the light from the star. Astronomers also used software to digitally subtract more starlight. Nevertheless, scattered light from HR 8799 dominates the image, obscuring the four faint planets. The exoplanets were discovered in 2007, 2008, and 2010 in near-infrared ground-based images taken with the W.M. Keck Observatory in Hawaii and the Gemini North telescope in Chile. The system is 133 light-years from Earth.
