University of Arizona's Roger Angel, pioneer of large, parabolic mirrors, has been inducted into the National Inventors Hall of Fame. The lab's large potato chip shaped primary mirrors for the Giant Magellan Telescope are among the most ambitious ever attempted. more..
AUSTIN — A study published in today’s Astrophysical Journal by University of Texas at Austin assistant professor Steven Finkelstein and colleagues reveals that galaxies were more efficient at making stars when the universe was younger. The announcement explains the team’s discovery, announced in the journal’s September 1 issue, that there are a lot more bright, highly star-forming galaxies in the early universe than scientists previously thought. "This was an unexpected result," Finkelstein said. "It has implications for galaxy formation at the earliest times" in the universe. For both studies, his team used galaxy observations from Hubble Space Telescope's CANDELS survey, of which he is a team member. more..
ATACAMA DESERT, Chile — Leaders and supporters from The University of Texas at Austin’s McDonald Observatory, along with representatives from an international group of partner universities and research institutions, are gathering on a remote mountaintop high in the Chilean Andes today to celebrate groundbreaking for the Giant Magellan Telescope (GMT). The ceremony marks the commencement of on-site construction of the telescope and its support base. The GMT is poised to become the world's largest telescope when it begins early operations in 2021. It will produce images 10 times as sharp as those delivered by the Hubble Space Telescope and will address key questions in cosmology, astrophysics and the study of planets outside our solar system. more..

FORT DAVIS, Texas — After several years and a massive team effort, one of the world's largest telescopes has opened its giant eye again. The Hobby-Eberly Telescope (HET) at The University of Texas at Austin's McDonald Observatory has completed a $25 million upgrade and, now using more of its primary mirror, has achieved "first light" as the world's third-largest optical telescope. "This upgrade makes HET the most powerful wide-field spectroscopic telescope worldwide, and we expect unique scientific discoveries from it," observatory director Taft Armandroff said. more..
