February 10th, 2018 – Field Trip Through the Solar System: Mercury to Pluto

Please join us at 8:00pm, February 10th, 2018 at Perkins Observatory for a presentation by James St. John from the Ohio State University at Newark Geology Department. James will discuss the geology and features of all the planets and major moons or our Solar System.  Plus hints of some major changes in the configuration of our Solar System.  You will not want to miss it!

Refreshments will be provided and if it is clear, please feel free to bring a telescope or binoculars to observe with afterwards.

CAS Unveils New Official logo

Columbus Astronomical Society Official Logo

The Columbus Astronomical Society would like to reveal our new official logo! Our logo represents several items of interest:

  • The constellations in the background show the sky around the constellation of Cassiopeia which is abbreviated as “CAS”.
  • The round logo represents looking through an eyepiece through a telescope and focusing on the State of Ohio.
  • The bottom of the state outline represents the dark foreground of trees and hills like what we see in the Hocking Hills. Our club has a long standing relationship with the Hocking Hills State Park.
  • The “star” in the middle represents Columbus, OH, our home. It also is the location, in reference to the background constellations, of the strong radio source of Cassiopeia A.
  • 1947 is the year of our founding.
  • And finally, the gradient color of the state represents the twilight sky: the transition between night and day.
