 Spring scene

Monday, March 9, 2015  7:00 p.m.  

Are you ready for spring's return?    After our long cold season, the air is warming, the duration of daylight increasing, and the ground is becoming verdant yet again.    Why do we experience profound changes during the various seasons?  Is it as simple a matter of Earth's tilt?  As we prepare to transition from winter to spring, join us for a talk about the astronomy of the seasons.


Exo planets

Monday, April 13, 2015    7:00 p.m.

We've discussed the worlds within our solar system.  Tonight, we extend our reach into the galaxy.  The Kepler Probe continues its search for exo-planets, those worlds in orbit around other stars.   How can the Keplerprobe find these worlds?   It is possible our galaxy might contain as many as one trillion planets.    How much can be know about them?

 Nymphs of Olympus

Monday, May 11, 2015  7:00 p.m.

An evening of constellation and planet mythology.  The Astronomy Cafe focuses on the ancient sagas of the stars.   We not only include constellation overlays, but also artwork based on the rich mythological traditions of the night sky.

Universa; expansion

Monday, June 8, 2015    7:00 p.m.

June's Astronomy Cafe takes us to the beginning of space-time.  How did the Universe start?  How did astronomers figure out that the cosmos actually had a beginning?   Was everything once condensed into a singularity?  Will the Unverse continue forever? Or, could the Big Bang model actually be incorrect?

Night sky above a canyon

Monday, July 13, 2015   7:00 p.m.

In January, we conducted a thorough tour of the winter sky.  Tonight, we explore the rich summer sky.    See the "Summer Triangle,"  "Hercules," "Draco the Dragon," "Delphinus the Dolphin," and, of course, the brilliant Milky Way, amongst other celestial wonders.   Join us as we explore the sky above the campfires.  

New Horizons spacecraft

Monday, August 10, 2015    7:00 p.m.

The New Horizons spacecraft made its closest approach to Pluto in July 2015.   What did New Horizons see?  What have we learned about the Pluto system?  What scientific equipment did New Horizons employ to study these outer worlds?   We venture out to the edge of the planet system to take a closer look at Pluto. 


Reservations not required.   Doors open half an hour before the presentation begins.  For more information, consult our, call 207-780-4249 or  or e-mail
