The Astronomy Cafe


The Astronomy Cafe  is a brand new planetarium event!  Once a month,attend an informal discussion about a different astronomical topic.  Each presentation includes aquestion/answer period and a night sky tour.  Admission by donation. (Suggested $5-7)


Monday, October 13, 2014     7:00 p.m.

October is a splendid month to observe the Milky Way Galaxy. Tonight, we explore the Universe of galaxies, with particular emphasis placed on our own Milky Way.    How do galaxies differ?  How did we determine the solar system’s position within our galaxy?  Discover the building blocks of the cosmos.

Bellicose Mars; jovial Jupiter; alluring Venus; crafty Mercury; wise Saturn.   The Greeks called them the “wandering stars,” for they moved ndependently against the stellar backdrop.   Steeped in ancient legend, we learn the stories and motions of theplanets, as well as how astronomers discovered the remote worlds beyond Saturn.

Exo planets

Monday, December 8, 2014    7:00 p.m.

In November, we 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?

 Orion the Hunter

Monday, January 12, 2015     7:00 p.m.

Tonight, we devote an entire hour to the winter night sky.   We explore the Winter Hexagon, the bridge of the Milky Way, Orion, the Pleiades, the Great Square and more.   We include a tour of the visible planets, and, of course, we spend a few moments with the Moon. 


Monday, February 9, 2015  7:00 p.m.

Though we associate the Aurora Borealis with winter, one can see the Northern Lights any time of year.  Their appearances in the mid latitudes aren't solely determined by the season, but also by solar activity.  Join us for an evening of beautiful aurora images and learn the fundamentals of space weather science.

 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.


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
