In addition to being a business tycoon and renowned philanthropist, Andrew Carnegie gave large amounts of his fortune to science. One of those endeavors is Carnegie Science. Dr. John Mulchaey, PhD. is an astrophysicist with the organization. He and his colleagues will be very busy next week studying the corona of the sun during the total solar eclipse. He joined Rick Dayton on KDKA to explain what they hope to learn as the sun is blocked by the moon on April 8.
