How a Trio of Observatories Around Tucson is Changing Astronomy
The “Tucson Triangle” is the greatest collection of scopes and spectrographs in the continental U.S.
Amid the burning Arizona sands, three peaks form a triangle of superlatives surrounding Tucson. Atop Mount Graham sits the world’s largest optical telescope. Mount Hopkins is home to North America’s second-largest single-mirror telescope. And Kitt Peak contains the continent’s largest single collection of mountaintop astronomical instruments.

Student-built satellite uses 'beach ball' for an antenna
CatSat is a small satellite carrying a new communications concept – an inflatable antenna – into space. The project provides a rare opportunity for students at the University of Arizona to get hands-on experience with spaceflight technology.
The project began in 2019 when Chris Walker, a UArizona professor of astronomy, along with a team of faculty members from other departments, submitted a proposal to NASA as part of the NASA CubeSat Launch Initiative. NASA saw potential and agreed to provide a launch vehicle for CatSat.
"The technology demonstrated by CatSat opens the door to the possibility of future lunar, planetary and deep-space missions using CubeSats," said Walker,...

Congratulations Dennis Zaritsky, Professor of Astronomy, named AAAS Fellow by the American Association for the Advancement of Science
Zaritsky, a professor of astronomy, is being honored for his contributions to the field of astronomy, including research that made connections between dark and luminous matter.
"Astronomical research serves to inspire and awaken curiosity in the broader commnity that we hope translates to other sciences, and even beyond science," Zaritsky said. "I hope that the enthusiasm generated by the University of Arizona's astronomy research program continues to get passed on to the students we teach and the general public."
Zaritsky earned his...
