The Richard F. Caris Mirror Laboratory will start fabrication of the seventh segment of the primary mirror necessary to complete the Giant Magellan Telescope. It marks a milestone in the search for other, potentially Earth-like planets and the exploration of the universe.

Regents Professors Marcia and George Rieke and UArizona alumna Jane Rigby were recognized for their accomplishments in astronomy and key contributions to the James Webb Space Telescope.

Climate models and geologic archives are at odds over whether Earth gradually warmed or cooled over the past few thousand years. Researchers tackle this global "temperature conundrum" in a new paper.

With NASA's James Webb Space Telescope, researchers are observing star formation in nearby galaxies with unprecedented resolution at infrared wavelengths.

Five UArizona faculty members have been named AAAS Fellows, a distinct honor in the scientific community bestowed by the American Association for the Advancement of Science. From using microbes to combat allergies to turning insects into food, the university's newest AAAS Fellows represent a broad range of research expertise.

NASA awarded nearly $3 million to the University of Arizona Kuiper Materials Imaging and Characterization Facility to support OSIRIS-REx sample science and much more.

The mystery of whether microbial alien life might inhabit Enceladus, one of Saturn's 83 moons, could be solved by an orbiting space probe, according to a UArizona-led study.

The university had $770 million in total research activity in fiscal year 2021 and retained its No. 1 ranking in astronomy and astrophysics expenditures at more than $113 million.

Black holes are surrounded by an invisible layer that swallows every bit of evidence about their past. Researchers are now using machine learning and supercomputers to reconstruct the growth histories of black holes.

University of Arizona researchers are teaming up with partners around the world to promote resilience and create solutions to global climate challenges.
