Guest Presentation at Space Place
"Two Years that Changed the Milky Way Galaxy: 1951 and 2018"
Tuesday, July 10, 2018
UW Space Place, 2300 S. Park St. (lower level of the Atrium)
Dr. Bob Benjamin, UW-Whitewater, will examine how our astronomical understanding of the structure of the Milky Way Galaxy has been a gradually unfolding process. He will focus on two years in particular, 1951 and 2018, when the first evidence for the spiral nature of our galaxy was discovered and 65 years later, when measurements of distances and sky motions of a billion stars were taken.
