Looking up at the sky in Tucson, the majestic Santa Catalina Mountains always catch the eye.

On this pleasant day when the autumn breeze cools the desert heat, I would like to share the story of the University of Arizona (UA), the pride and heart of this beautiful city.

The University of Arizona, established in 1885 before Arizona became an official state, is the first university in the region and the flagship public university representing the state.

As of the fall semester of 2025, the total enrollment is 54,384 students.

With 43,294 undergraduates and 11,090 graduate students exploring in-depth academic pursuits, the campus is always filled with youthful energy.

The main campus, located in the heart of downtown Tucson, spans about 230 acres, and interestingly, the boundary between the campus and the city is quite blurred.

Walking along the charming cafes and shops surrounding the university, you will have a magical experience of stepping right into the impressive red-brick UA campus.

In terms of academic achievement, UA boasts a world-class reputation.

Operating a total of 22 colleges and graduate schools, it nurtures talent in various fields, particularly in astronomy, optics and photonics, medicine, and various engineering disciplines, achieving top-tier research results.

Notably, it leads NASA's Mars lander project 'Phoenix Lander' and develops the world's largest astronomical telescope lens technology, establishing a unique position in space science and optics that beautifully complements Tucson's stunning night sky.

For those considering college or studying abroad, I will also summarize the tuition information that many are curious about. As a public university, the tuition varies based on residency; for in-state residents, the undergraduate tuition is approximately $13,573 per year, while out-of-state residents and international students pay around $39,903 per year.

Some costs may vary depending on the major or specific semester circumstances, so if you are preparing for admission, it is advisable to check the official university website for the accurate guidelines for the current year.

The economic and cultural impact of UA on the entire city of Tucson is unimaginably vast. It employs numerous faculty, world-class researchers, and service staff, making it the largest employer in Tucson, while the housing demand and consumer spending generated by thousands of students are key drivers of the city's economy.

Moreover, the steady presence of Korean undergraduate and graduate students and faculty who work hard away from their homeland provides a solid and valuable human foundation for the Korean community in Tucson.

In this way, the University of Arizona is an indispensable part of understanding Tucson's past, present, and future, serving as the heart of this city.
