Learn about the contribution of MOSFIRE at the W. M. Keck Observatory public astronomy lecture at 7 p.m., Wednesday, May 22, at Kahilu Theatre. UCLA’s Dr. Ian McLean will describe MOSFIRE, the newest and the most advanced astronomical instrument available today. Will include the technical challenges developing and commissioning this new multi-year, multi-million dollar instrument. He will also share early science results ranging from the discovery of ultra-cool, nearby substellar mass objects, to the detection of oxygen in young galaxies only 2 billion years after the Big Bang. The event is free and all are invited.
