How to Fly Close to the Sun with Astronomer Andrew Fraknoi

The fastest moving human-built object ever, the Parker Solar Probe, will enter the sun’s atmosphere on December 24th. It’s the closest any artificial object will have gotten to the sun. We’ll talk with astronomer Andrew Fraknoi about what the solar probe hopes to learn and other exciting developments in astronomy, such as the discovery of the hungriest black hole yet found – it consumes the mass of our sun daily. And as we approach the shortest day of the year, we’ll contemplate how the ancients celebrated the winter solstice, and why we can thank a planet that crashed into Earth for our seasons.

Guests:

Andrew Fraknoi, astronomer and professor, Fromm Institute at the University of San Francisco and the OLLI Program at SF State; lead author of the most popular introductory astronomy textbook in North America; Website URL: www.fraknoi.com
