About

YSPA is a six-week program for rising high-school seniors that blends a two-week online directed self-study with a four-week residential research experience at Yale. The program is designed for students with strong preparation in physics, math, and computing who want a rigorous, research-driven introduction to astrophysics. Tuition for 2025 is $8,000, covering academic programming, room and board, and most program costs. Limited need-based financial aid is available.

YSPA begins with a structured online module focused on foundational astronomy, physics, and Python. On campus, students take accelerated classes, analyze real data, and work in small teams on a mentored research project. Instruction occurs at the Leitner Family Observatory & Planetarium and its computer labs; evening observing sessions use Yale’s telescopes as well as remote observatories to collect original data for student projects. The pace is undergraduate-level: data reduction, modeling, and analysis culminate in a final presentation and paper-style write-up. A sample schedule includes daily classes, lab time, evening observing blocks, and community events.

Admission is highly competitive and limited to 32 rising seniors. The application emphasizes academic preparation, recommendations, and demonstrated motivation for physics/astronomy and computation. Because YSPA is so specialized its application pool is by nature somewhat self-selecting.

Instruction and research supervision are led by Yale astronomy faculty and staff at the Leitner Observatory, with graduate-level teaching assistants providing day-to-day mentorship in the dorms, labs, and during evening observing. The student-to-instructor ratio is intentionally small to support advanced coursework and individualized guidance on data analysis and modeling.

Students complete an authentic research project using research-grade instruments and methods, producing a final talk and written report. YSPA is probably the most prominent summer program in the country to focus specifically on astrophysics, although students also engage with computational physics and more generalized data-driven research topics. YSPA is an unusually focused program—and for the right student, it might be ideal.
