Have you visited us lately? We have a super Saturday lineup for you!
At 11:00am, come check out ""Khrumka's Adventures in the Winter Forest." At 1:00pm, we'll feature ""Aurora: Lights of Wonder."" Tickets are $5 per person and are available at hdplanetarium.ticketleap.com.

☀️🕐 Happy Fun Fact Friday! 🌙
Did you know Daylight Saving Time isn’t based on astronomy — but it feels like it is?
Humans move the clock to “save” sunlight, but the real reason days get longer or shorter comes from Earth’s 23.5° tilt and its orbit around the Sun. 🌍✨
So when you “fall back” or “spring forward,” you’re really just syncing with the sky’s seasonal dance! 🌞🌌

Happy ""Thoughtful Thursday"" everyone!

Tonight should be a good time to try and spot Mercury as it will appear to be at its farthest distance from the Sun. It will officially set at 5:52pm. So from there, you will have about one hour to catch Mercury in the Western sky, near the horizon.
