The European Southern Observatory, or ESO, has signed an agreement with a large international consortium that includes the University of Michigan for the design and construction of the Multi-Object Spectrograph, or MOSAIC.

The instrument will be part of the 39-meter Extremely Large Telescope, or ELT, which will be the world’s largest optical telescope when completed in about four years. With the ability to measure light from more than 200 sources simultaneously, MOSAIC will be used to trace the growth of galaxies and the distribution of matter from the Big Bang to the present day.

“This instrument and this telescope will be, in almost all cases, better than the JWST in terms of its power to see the distant past and in terms of its fineness of detail,” said Christopher Miller, U-M professor of astronomy.
