W.A. Gayle Planetarium, Science education center in Oak Park, Montgomery, United States

The W.A. Gayle Planetarium is a planetarium in Oak Park in Montgomery, Alabama, with a 159-seat theater. Its Super MediaGlobe II digital projection system, installed in 2014, simulates the night sky. The building also holds a one-fifth scale model of the Hubble Space Telescope, images of celestial objects, and a black-light hallway on the history of astronomy.

The planetarium was dedicated on September 25, 1968, and named for William Armistead Gayle, mayor of Montgomery from 1952 to 1959. Troy University ran it for the city from 1972 until 2022, when management returned to the City of Montgomery. It reopened to the public at the end of January 2024 after a COVID-19 shutdown.

The planetarium is named after William Armistead Gayle, mayor of Montgomery from 1952 to 1959. Its public and group shows pair a full-dome astronomy film with a guided tour of the night sky over Montgomery, pointing out visible planets, stars and constellations, and usually close with a short laser show.

Public shows run only on Saturdays, at 10 am, 11:30 am, 1 pm and 2:30 pm; the planetarium is closed Sundays and Mondays. Tickets are sold at the gift shop 15 to 20 minutes before each show. Groups of 10 or more book by appointment Tuesday through Friday through the planetarium office.

The Hubble model inside is a one-fifth scale replica, not a full-size one. The theater's Super MediaGlobe II projector was installed in 2014, replacing earlier equipment. A black-light hallway traces the history of astronomy, pairing with images of celestial objects on display.
