Don’t let Astronomy Day pass unnoticed.

The Marshall W. Alworth Planetarium is offering a bunch of free space-related events for children and adults from 10 a.m. to 5:30 p.m. Saturday at the University of Minnesota Duluth.

There will be a dark-sky program, full-dome videos and documentaries, lectures and programs on colonizing space, space medicine, aerospace engineering, astrophotography and mini-asteroids.

Dr. Matthew Andrews of UMD will present “Hibernation in Space,” a futuristic look at how humans can endure long travel times in space.

Dr. George Shaw, professor emeritus at Union College, will present “Terraforming Mars,” ideas on how to turn the red planet into an Earth-like environment. For more info, go to d.umn.edu/planet.
