UArizona Sky School
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 distances. Months later, standing over his desk, he had data confirming that the international team of astronomers working on the James Webb Space...
Steward Observatory’s Buell Jannuzi wins UArizona’s Distinguished Head/Director’s Award
This week, Buell Jannuzi, Head of the Department of Astronomy and Director of Steward Observatory, receives University of Arizona’s Distinguished Head/Director’s Award, an honor that reflects his abilities as a leader to engender trust, foster collaboration, and recruit and retain a diverse community of high-achieving staff, students and faculty.
"We are extremely fortunate to have such a dedicated and effective leader for Steward Observatory and the Department of Astronomy,” said Regents’ Professor George Rieke. “In a limited-funding, highly-constrained environment he has, nevertheless, managed to extend and expand the ambition of the faculty and staff of the department and...
