Light: Its Mysteries & Hidden Secrets
with Joe Dougherty

When you hear or read about astronomy, descriptions of stars or galaxies, or the discovery of planets in a distant solar system, do you ever wonder how scientists discovered all that information?

It is amazing to be reminded that man has never traveled further than the moon and our farthest and most sophisticated spacecrafts have only recently ventured into interstellar space. Yet, we know a tremendous amount about galaxies millions of light years away.

This presentation will explore light….what it is and how scientists have harnessed it to reveal much of what we know about our universe. Specifically, we will learn about the chemical composition of stars, how to determine the distance and temperatures of astronomical objects and how scientists are discovering new “exoplanets” daily.

Joe Dougherty is the President of the Litchfield Hills Amateur Astronomy Club. He has specialized in the field of astro-imaging for nearly 10 years. He has given numerous presentations on imaging to the public and other amateur astronomers over the years. Recently, he has been exploring the use of new tools, software and imaging cameras used in the field of Spectroscopy of stars. He resides in Waterbury, CT and holds an M.B.A. and B.S. in Mathematics.
