Horwitz-DeRemer Planetarium

With Earth Day quickly approaching on April 22nd, here's a Excellent Earth Fact4 U! According to a 2015 study, it is estimated that there are roughly 3 trillion trees on earth, give or take a few million. 8 billion people = roughly 400 trees per person!

Are you all still on an solar eclipse high like we are at the Horwitz-DeRemer Planetarium!? Check out a combo of pics from our crew. These were taken from Waukesha, Milwaukee, Texas, & Arkansas. Drop your eclipse pictures in the comments if you want to share! #totaleclipse2024

Don't forget! The Planetarium will recycle your eclipse glasses for you! Just drop them off by April 30th. We will send them on for inspection & they will be used in Central American this coming October for their Annular eclipse!

Time is running out to view some of our beloved winter constellations. The stars famous for appearing in the wintertime sky are now setting soon after sunset these days, as spring gets well and truly underway. Look west about an hour after sunset tonight to catch them.

Have you signed up for Sunset Meditation coming up on Wednesday? This beautiful evening begins @hdplanetarium at 7:30pm with a peaceful planetarium show. Immediately following, 1 of Retzer's amazing naturalists will take interested participants on a evening hike on the trails.

Have a great week, everyone! #wherethestarshangout

We have a great pair of shows for this Saturday! At 11am, we'll show ""One World, One Sky: Big Bird's Adventure,"" and ""Galileo: The Power of the Telescope"" at 1pm. Save your seats online at hdplanetarium.ticketleap.com. Have a great weekend, everyone!

The large constellation Virgo is above the eastern horizon after sunset tonight. Virgo’s brightest star is Spica, which shines at magnitude 1, is actually a binary pair. The two stars are too close to split and orbit each other in just 4 days. SOURCE: astronomy.com

This ""Thoughtful Thursday"" quote couldn't be more perfect for this week. Feel free to share your eclipse experiences from Monday below. We hope you were able to view it someway, somehow, somewhere. #wherethestarshangout

For the next few mornings, Mars & Saturn will be visible, but very low in the E-SE, so you’ll need a very clear view of the horizon. And, they'll be just above a slim, waning crescent Moon. The 2 planets are almost identical in brightness this month & only about 1 degree apart.

Can U believe it's the 1st full week of April?! And, the solar eclipse is TOMORROW!?! Here's our schedule! If U can't visit us tomorrow, be sure U R looking at the sky (safely) tomorrow (weather permitting!) The next U.S. Solar Eclipse won't be until the year 2045!
