For a scientist, the universe is an exotic playground for physics and biology. For a writer, it’s a blank canvas with vast potential.

For Chris Impey, it’s both.

Impey, a distinguished professor at the University of Arizona, has written several books about time and space including “How It Began: A Time-Traveler’s Guide to the Universe” and “How It Ends: From You to the Universe.” “Shadow World,” his first novel, debuted last year.

On April 27, Impey will talk at “Star Struck—Fact and Fiction in the Universe,” a fundraiser to benefit the Pima Library Foundation. The evening, which starts at 5:30 p.m. at the Flandrau Science Center & Planetarium, 1601 E University Blvd., includes wine and cosmic creations from Gallery of Food.

Tickets are $35 ($25 is tax deductible) and can be ordered at

The event is presented by the Circle of Book Clubs, a fundraising committee that sponsors author events to benefit the library foundation.

A book signing will follow Impey’s talk. The University of Arizona bookstore will also bring a selection of his books for purchase.
