The University of Wyoming Harry C. Vaughan Planetarium will switch its lineup around during April.

“We are changing up our schedule a bit by moving our music programs to Friday evenings at 7 p.m.,” says Max Gilbraith, the planetarium’s coordinator. “Our live science talks will be Saturdays at 7 p.m.; full-dome films will continue on Saturdays at 2 p.m.; and even-numbered Tuesdays at 7 p.m. are our ‘Wyoming Skies’ constellation tours.”

To get tickets or receive more information about programs, email planetarium@uwyo.edu or leave a voicemail and a call-back phone number at (307) 766-6506. Tickets are $5 for the public and $3 for students, senior citizens, veterans, first responders and those under 18. Seating is free for children under 5.

Reservations or pre-purchase is not required, and walk-ins are welcome. Tickets can be purchased online with a credit card, reserved by email or voicemail, or purchased at the start of the show. Cash or check is accepted at the door. The planetarium, which seats 58, is in the basement of the Physical Sciences Building. Seating is on a first-come, first-served basis outside of designated ADA/wheelchair seating.

To pay for tickets with a credit card, go to https://www.uwyo.edu/uwplanetarium/ticket.aspx. For a group larger than six, email the planetarium for a private show at https://uwyo.sjc1.qualtrics.com/jfe/form/SV_bKuqIynOn7gFK2F. Tickets for private shows are the same as the public programs.

A film and special live talk for audiences will be featured each week. All programs are approximately an hour in length. As time allows, a portion of the show also may focus on a live sky tour or supporting information related to the film’s topic.

— Saturday, April 15, 7 p.m.: “James Webb Space Telescope.” The next-generation space telescope launched in 2021. The epic mission to send a tennis court-sized observatory past the moon will reveal the mysteries of the universe like never before. This program will detail the exciting science objectives and the knuckle-biting engineering feats that have gone into our next eyes in the sky.

— Tuesday, April 18, 7 p.m.: “Wyoming Skies.” The program provides an exploration of the stars, constellations, planets, meteor showers and other celestial phenomena visible from Wyoming for the season.

And, is it a future home for humans? Landers, rovers, probes and satellites have returned data to Earth for decades, and we have more clues every day.
