Heaven’s Touch: From Killer Stars to the Seeds of Life, How We Are Connected to the Universe

We may feel isolated from the universe on a planet so small. But, says astronomer James Kaler, we are more connected to our corner of existence than we think. Today on Focus, he joins us to talk about his new book Heaven's Touch, in which he explores the variety of ways that the universe affects events on our own planet, from the gravitational effects of Jupiter to solar flares to deep-space cosmic rays.

Guest: James B. Kaler, Ph.D. (Professor Emeritus of Astronomy at the University of Illinois; author of Heaven's Touch: From Killer Stars to the Seeds of Life, How We Are Connected to the Universe)
