Soak in the summer solstice on Sunday, June 20

What comes to mind when you think of summer? Our long days and short nights around the summer solstice may mean less time for stargazing, but there are secrets to unlock even in our Sun!

Join Ranger Laurel on a crash course adventure through solar astronomy. Hear about the legends we tell, the science behind our knowledge, and the data of our universe locked up in something as simple as a beam of sunlight.

Stream the podcast or download it ahead of time to tune in while you soak up the Sun.
