On the evening of Oct. 28, 2025, the Planetary Science Institute hosted a Halloween-themed star party.

Attendees were invited to learn more about the Institute and the exciting science conducted here. They were also welcome to view the Moon and Saturn through four telescopes, talk to PSI co-founder William Hartmann about the history of space art, witness the making of a comet, enjoy treats and learn about meteorites. They also created their own space art in the likeness of topographic maps and learned about 3D printing.
