In a talk at the Oliver Wolcott Library in Litchfield, Joe will discuss the nature of Light.  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 that no human has ever traveled further than the moon and our farthest and most sophisticated spacecraft 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.  We’ll 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.

No observing – talk only.  The event is free, but registration is required.  Please contact the Oliver Wolcott Library to register:  Register here.
