At the kind invitation of Dr. Rebecca Oppenheimer, members of the CHARA collaboration gathered at the American Museum of Natural History in New York City for a two-day review of scientific and technical progress made during 2006. This happened in coincidence with the opening of a new exhibit on [exoplanet detection instrumentation](http://www.amnh.org/exhibitions/exoplanets). On display in this exhibit is the famous 20-ft Michelson Interferometer, on special loan to the AMNH, which was used on the Mount Wilson 100-inch telescope from 1919 to about 1927. That instrument began the Mount Wilson tradition of interferometry, which culminates today with the CHARA Array.
