Chasing Venus

(Courtesy Photo) Author Andrea Wulf will discuss her new history book “Chasing Venus: The Race to Measure the Heavens” on May 30 at Arnold Arboretum. The book is about the scientific community’s worldwide effort, despite enormous challenges, in the 1760s to use a rare astronomical event to make the first measurements of the distance between planets in our solar system. The event, known as the transit of Venus, will occur again next month. See Sights & Sounds listing.
