On April 4, 2012 a new instrument obtained “first light” on the Keck I Telescope at the W. M. Keck Observatory on Mauna Kea. Known as MOSFIRE, for Multi-Object Spectrometer For Infra-Red Exploration, it is the most advanced capability available today to study star formation, galaxy formation and the early universe. What makes this huge, vacuum-cryogenic instrument unique is its ability to select up to 46 individual objects in the field of view and then record the infrared spectrum of all 46 objects simultaneously. Professor Ian McLean of the University of California at Los Angeles and co-principal investigator of MOSFIRE will describe some of the technical challenges that were overcome in developing and commissioning this multi-year, multi-million dollar instrument as well as 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.

Excellent find! Great job! Gigantic ring system around J1407b much larger, heavier than Saturn’s : NewsCenter bit.ly/1zVwcbP
MOSFIRE and NIRSPEC are the instruments tonight. Observers are from Subaru and CIT-Y. Sun set 06:21:00pm rise 06:48:00am
The sky is ready for HIRESR and NIRC2-LGS. Our observers from ANU and UCSC are also ready. Sun set 06:20:00pm rise 06:48:00am
@AsteroidEnergy See! You could barely name enough for two hands! ;)
