NEW ...public show punch cards! You may purchased these in quantities of 5 or 10 visits. They would certainly make a great gift for any astronomy-lover in your life! Purchase yours at the planetarium with any one of the educators OR with a Retzer front desk attendant!

2nd-brightest planet, Jupiter, rises each day while the Sun is still in the sky. Once evening twilight sets in, start looking for it high in the S-SE sky early in the month & high in the S later on.
It’s not as bright as Venus, but it easily outshining all the stars!

Has your gift game been lacking lately? Danielle's got the Retzer gift shop looking so on point, you'll wanna shop 'til you drop! And, we're always adding new goodies - when's the last time you stopped by? #wherethestarshangout

Another great week here!

Happy Thursday, all! Do you have plans?
Because, the moon reaches the new moon phase tonight! Therefore, if you can, and the weather cooperates, it would be an ideal night for stargazing!

"Happy #PiDay! 🥧✨
Today (3.14) we celebrate π — the number that helps us measure circles. And in astronomy, circles are everywhere!
From the Sun and Moon to planetary orbits and swirling galaxies, π helps scientists measure worlds, map the cosmos, and even understand the shape of space itself.
So whether you're enjoying a slice of pie or exploring the universe under our dome, remember: π connects your plate to the planets. 💫
