Topic: A Tour of the Heavens
Speaker: Roy Bishop
February’s presentation will be a selected sequence of astronomical
images in electronic form, assembled from various sources including
cameras on tripods, Earth-based telescopes, and instruments in space
including the Hubble Space Telescope. In addition to showing pretty
pictures, I shall describe the objects in the pictures — where they
are, what they are, how big they are, and their evolution.
