Date: Tuesday Feb 23, 2016
Time: 5:30 p.m. -
As part of Southwest Harbor Public Library’s One Park – One Read program for the Acadia National Park Centennial, retired Acadia National Park Superintendent Paul Haertel and Park Lead Education Ranger Michael Marion will discuss Acadia’s night sky and the beauty, history, and science addressed in book The End of Night: Searching for Natural Darkness in an Age of Artificial Light by Paul Bogard on Tuesday evening, February 23, 5:30.
Haertel will discuss the aesthetics of a light pollution-free night sky and his remembrances of looking at night skies as a child in an area that is now filled with artificial light. He will also discuss his experiences working in other national parks and how light pollution has affected their night skies. Haertel will also touch briefly on Einstein’s Theory of General Relativity and explain how “spacetime,” a four-dimensional coordinate system which contains three spatial dimensions and one time dimension, helps us understand the universe.
Marion will discuss the importance of understanding the night sky as we know it now in order to protect its future. For example, work is being done to document a baseline of current light pollution in an effort to understand changes over time. Just like fauna and flora, the night sky is a natural resource that needs protection. Marion will demonstrate how to measure light pollution and will show light pollution maps of Mount Desert Island. He will also discuss what Acadia National Park is doing to become a designated Dark Sky Park through the International Dark-Sky Association. This presentation will include inspirational photographs of the galaxy and stunning images of our very own night skies.
Weather permitting, immediately following the program participants will be invited to the ball field at Pemetic Elementary School for some winter star gazing. Marion will point out key constellations, planets, and what to look for in a winter sky.
