Calendar of Events
The Richland Astronomy Society holds our monthly club meetings prior to the public opening. Listen to us discuss the possibility of life on Mars, the latest info on Black Holes, new comets, space flight and NASA, and even just a good old Taurus Session. You are very welcome to join our meeting, listen to our ideas and add your own input.
Bring your telescope! If you don’t know how to use it one of our staff will show you. If it doesn’t work we may even be able to fix it. And bring your camera… Take a picture through the big telescope! You can brag that you used the largest telephoto lens in the area. You’ll find us a very family oriented organization and we welcome all “stargazers”… Even “stargeezers”!
We believe that Science is for everyone. Don’t worry for one second that you’re not knowledgeable enough to join us for a great evening – or too young or old. Our goal is to make astronomy fun and enjoyable for all of our visitors!
What to Expect
If this is your first visit to an Observatory, don’t be worried. We love our family oriented atmosphere and we love to share. Modern restroom facilities are available on premise and almost all areas are handicapped accessible. Parking is available in front of the ClubHouse/Dome Area.
Don’t forget… Astronomy happens outside, so dress accordingly! Plan to spend your evening outdoors and provide for your comfort. You are welcome to bring camp chairs, blankets, food and beverages. If you do not have chairs, there are always a few around to make your evening more enjoyable. Because we are outdoors, remember that you are exposed to poison ivy should you wander into the woods – and nocturnal wildlife and insects. Small children should be supervised.
What If It’s Raining Or Cloudy?
No worries. We always have some type of program on our public nights – no matter what the weather may bring! Both the Dome and the Education Building are sheltered, so always expect to catch the latest astronomy video and some of the best astronomy programs you’ll find anywhere! During the months of December, January and February, the Observatory is closed to the public. It’s not that we mind the cold… But the driveway is steep and we do not wish our visitors to take any chances with ice and snow.
How Much Does It Cost?
Not a thing. We love astronomy and all the work we do is strictly volunteer. Of course, we do appreciate donations… It can be monetary, if you like – but we very much appreciate astronomy books, astronomy related toys, astronomy videos, old telescopes and even astronomy knick-knacks!
We know the hobby of astronomy is expensive – and that’s why we have telescopes that are meant for public use. That’s right! We have telescopes that YOU can use, too! If you’re not sure of which one? Just ask any of our friendly, helpful staff and they will guide you to your own scope and show you how to use it.
