Congratulations to the CatSat Team!
CatSat, the University's first satellite built entirely by students, broke free of its 2nd stage launch vehicle around 11am MST on Monday July 15th. The University of Arizona student team behind this endeavor is now in regular contact with CatSat using the ground station they built at the Arizona Research Building. There are typically two passes over Tucson a day and the team is busy commissioning the satellite during those passes.
Reflecting hope: Concentrating solar power can feed the grid and perhaps even remove carbon from Earth's atmosphere
In recent years, Heliocon and the promise of CSP has attracted the interest of two of the best mirror and optics experts on earth: Roger Angel and Daewook Kim of the University of Arizona and its Wyant College of Optical Sciences, and Department of Astronomy and Steward Observatory.
Angel is the current and founding director of the UA’s famed Mirror Lab, whose large-mirror innovations have revolutionized ground-based astronomy.
Kim’s expertise in optical engineering has ensured precision and the best-possible views of the Universe from many existing world-class instruments, including the coming Giant Magellan Telescope with its seven 27-foot diameter mirrors. ...
UArizona Sky School
UArizona Sky School provides immersive, inquiry-based science programs to Arizona K-12 students. Field experiences focus on science areas such as sky island ecology, earth sciences, dendrochronology, hydrology and astronomy. UArizona science graduate students serve as instructors and mentors. For many of our public-school students, this is their first visit to public federal land, their first experience hiking or their first chance to interact with or see themselves a professional scientist and researchers.
Giant Magellan Telescope Enclosure Ready for Construction
The Giant Magellan Telescope (GMT) and IDOM today announced that the telescope’s enclosure, set to be one of the world’s largest astronomical facilities, passed its final design review and is now ready for construction in Chile. The review marks a major milestone for the telescope, which is now 40% under construction. This also marks an...

Glimpses of a volcanic world: New LBT images of Jupiter's moon Io rival those from spacecraft
New images of Jupiter's volcano-studded moon Io, taken by the Large Binocular Telescope on Mount Graham in Arizona, offer the highest resolution of Io ever achieved with an Earth-based instrument. The observations were made possible by a new high-contrast optical imaging instrument, dubbed...

James Webb Space Telescope spots the two most distant galaxies ever seen at cosmic dawn
When Kevin Hainline saw the data on his screen, he jumped up from his desk, startled by what he saw. In January 2023, Hainline – an associate research professor in the University of Arizona Department of Astronomy and Steward Observatory – was the first person to ever lay eyes on the galaxies JADES GS-z14-0 and the slightly less distant GS-z14-1. At the time of their discovery, these galaxies were merely two candidates among the hundreds Hainline had discovered, each one requiring careful follow-up observation to help confirm their extreme...
