Many SETI Institute donors give monthly and receive benefits as SETI Stars. One-time gifts are also gratefully accepted—just let us know which you prefer. In addition, your contribution could be doubled: many employers offer matching gifts. You might also choose to contribute through a workplace payroll deduction, donor advised fund, event or program sponsorship, or another method.

However you choose, your gift will empower our mission to explore, understand, and explain the origin and nature of life in the universe. If you have any questions about giving to the SETI Institute, please call us at 650-961-6633 or email development@seti.org.
