    The bright star epsilon Aurigae eclipses every 27 years for nearly 2 years. The current 2009-2011 event was rich in research opportunities (see list of recent publications on main page).  We made use of a wide array of ground based and space based telescopes to provide new insights into the nature of this enigmatic binary. Prior eclipses included 1983, 1956, 1929 and prior, where the nature of the eclipsing object was deduced, but firmly demonstrated by our interferometric imaging during 2009 and 2010.
