UT Austin is one of twelve partner institutions developing GMT, which is under construction at Las Campanas Observatory in Chile and, when completed, will be the world's largest telescope, with a resolution ten times that of the Hubble Space Telescope. In recognition of the gift, the Director's House at UT Austin's McDonald Observatory will be renamed the David G. Booth Director's House at the McDonald Observatory.
Booth's previous gifts to UT Austin have supported the Blanton Museum of Art, the McCombs School of Business, Texas Athletics, and the Lady Bird Johnson Wildflower Center. The co-founder and executive chair of Dimensional Fund Advisors signed the Giving Pledge in 2018.
"David Booth's generous support will ensure UT students and faculty can use the Giant Magellan Telescope to study some of astronomy's most pressing questions," said McDonald Observatory director Taft Armandroff, who also serves as vice chair of the board of the Giant Magellan Telescope Organization. "The GMT will offer Texas astronomers unique opportunities such as studying the atmospheres of nearby exoplanets to better understand how common Earth-like planets are."
