Giant Magellan Telescope

The University of Texas at Austin is a partner in an international consortium of science institutions building the next generation, 24.5 meter, Giant Magellan Telescope at Las Campanas, Chile. Construction is underway at this premier viewing site. Preparation of the Spincasting oven for the fourth primary mirror continues into 2015 at Arizona's Steward Observatory Mirror Lab.

Hobby-Eberly Telescope Dark Energy Experiment

In August 2013, an upgrade began for the 9.2 meter Hobby-Eberly Telescope. A widened field of view, and 150 integral field spectrographs will give HET the ability to map the expansion of the early universe. Scheduled to begin in 2015, the HETDEX survey will precisely measure more than 800,000 galaxies, to examine their distribution as the universe evolved.
