Public Event on Exoplanets at Dyer Observatory:

Public nights at Dyer Observatory
are typically sold out a month in advance and draw about 100 visitors, limited only by the available parking on the mountain. We will provide transportation to and from Dyer for a special DDA-sponsored public event on exoplanetary dynamics and astrobiology on May 24th at 7 pm.

We plan a short introductory primer on exoplanets, followed by a 4-6 member panel debate and Q+A session on what new data reveal about the possibility of life on other worlds.

If you would like to participate in this public event as a speaker, panelist, or guest, please email Kelly Holley-Bockelmann ( with the subject line 'DDA at Dyer'.
