Free Telescope Viewing Session this Saturday

We had to cancel the session on Sept. 23 for inclement weather.   We are planning to reschedule soon … please check back for the next date.  Thank you!


Join the Casper Planetarium for a good look at the moon, Saturn, and star clusters.  We will have several telescopes set up on the lawn this Saturday evening starting at 7:30, as well as people to help you find the most interesting sights in the sky.   If you have your own telescope, feel free to bring it along.   This event is “weather permitting,” so if it’s cloudy or rainy, we will reschedule for a later date.   Stop by 904 North Poplar and check out the skies with us.

Composite Image from the August 21 Solar Eclipse

We received 6 drawings from eclipse watchers who participated in our Corona Composite Image project.   Before the invention of photography, scientists would draw the corona during an eclipse, and then combine their drawings to create a final image.  Like those past scientists, each of our participants saw the eclipse a little differently.  The black and white drawings are the originals.  We’ve colorized them in the composite to help the individual layers stand out from each other.

Stars: the Powerhouses of the Universe.  Every star has a story. Some are as old as time, faint and almost forgotten. Others burn bright and end their lives in powerful explosions. New stars are created every day, born of vast clouds of gas and dust. Through every phase of their existence, stars release the energy that powers the Universe.

Journey to the farthest reaches of our galaxy and experience both the awesome beauty and destructive power of STARS.
