Our newest show in Hohfeld Hall illustrates how life thrives even in the most inhospitable places on Earth—and possibly elsewhere in our Solar System, too. Take your curiosity to the next level by exploring an array of resources below.

Extreme Life is a live, 15-minute program hosted by Morrison Planetarium presenters in Hohfeld Hall. Showtimes are Monday-Friday at 1:40 pm, and Saturday-Sunday at 11:40 am, 1:40 pm, and 3:40 pm.

It’s tardigrade time!
