Keck Interferometer

Work is currently underway to combine the light from the Keck telescopes to form another large stellar interferometer, in just the same way as is being done at VLT.

Similarly, there are also plans to install several 2m outrigger telescopes, and the Keck adaptive optics/interferometry project is a significant cornerstone of NASA's Origins Program, which seeks to identify and characterize possible Earth-like planets around neighboring stars. In 2005 the Keck Interferometer team announced that it had achieved a 100:1 nulling of the light from Vega and two other stars, and work is ongoing to increase nulling to the point where light from circumstellar disks and perhaps planets becomes visible.
