M31Greetings from the professional and amateur astronomers who comprise the Astronomical Society of Las Cruces (ASLC). The club was formed in 1951 by a group of dedicated astronomers including Clyde Tombaugh, who had discovered Pluto just 21 years earlier. For over 60 years, we've been sharing a little bit of the universe with our community under our beautiful Southern New Mexico skies.

The club has a variety of ongoing observing, education and public outreach programs. We host a public Moongaze each month, offer beginning astronomy courses and support countless star parties for schools, scouts and various organizations. We also hold a meeting each month which includes a featured presentation.
