Oct. 3, 2023 Satellite brightness threatens ground-based astronomy, research shows UArizona faculty and students are part of an international study confirming that deployed satellites like BlueWalker 3 are as bright as the brightest stars seen by the unaided eye and pose a challenge for ground-based astronomy.
Sept. 29, 2023 The last required piece of the world's largest telescope takes shape at UArizona The Richard F. Caris Mirror Laboratory will start fabrication in the final stage 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.
Sept. 27, 2023 Tree rings reveal a new kind of earthquake threat to the Pacific Northwest The findings from new research, led by University of Arizona dendrochronologist Bryan Black, could have implications for seismic preparedness measures in the region.
Sept. 24, 2023 A gift from space: UArizona-led OSIRIS-REx mission delivers largest-ever asteroid sample to Earth The delivery from the asteroid Bennu, seven years after the spacecraft launched, marks the end of the space-voyaging phase of the mission. Scientists will now study the rocks and dust to better understand the origins of life on Earth.
Sept. 24, 2023 Bennu sample delivery marks the start of extended OSIRIS-APEX mission After dropping off its historic sample from asteroid Bennu, the OSIRIS-REx spacecraft is headed to its next target: another potentially hazardous near-Earth asteroid, called Apophis.
