Lowell Observatory
If you love the night sky - the stars and the galaxies that exist above us, then you do not want to miss Lowell Observatory in Flagstaff. Sitting on top of Mars Hill Mesa, this observatory will likely change the way you view our existence. Since its inception, the Observatory has been home to many discoveries, including the first detection of the expanding nature of the universe; the discovery of Pluto and its atmosphere; Moon mapping for the Apollo Moon mission; the rings of Uranus and many more. Because of the incredible scientific and cultural background of Lowell Observatory, it is recognized as a Registered National Historic Landmark, an Arizona Treasure, and has been named one of “The World’s 100 Most Important Places.” And personally, we agree and see what the fuss is all about. Lowell Observatory is a stop you definitely want to make time for when you visit Flagstaff, Arizona.
So when you do visit, there are some things that Lowell Observatory offers that you won’t want to miss out on. First, we recommend doing your own research before you come! There are so many programs, buildings, telescopes, historical artifacts, and events to see that Lowell is a place you will want to return to for another visit.
What to See at Lowell Observatory
- The Giovale Open Deck Observatory A new public observing plaza that features six advanced telescopes that showcase a wide range of celestial life. This will give you a viewing experience like none before. This is where you can geek-out with hands-on experience.
- Tour of the Clark Telescope This is the oldest building at the observatory. The Clark telescope was built in 1896 and used to uncover the first evidence of the expanding nature of the universe. This telescope and the building that houses it should not be missed! This telescope will make you feel like a kid again, full of wonder and grandeur.
- Astronomy Discovery Center A new addition to Lowell Observatory featuring interactive exhibits for kids including Orbits Curiosity Zone, “Imagine the Universe” Live Play, Stardust Lab Astronomy Gallery, Celestial Visions Show, Origins Gallery, and a Rooftop Stargazing Tour. There's so many things to explore and take in that you'll need to take coffee break at the Planet X Cafe.
- So much more! To quote our friend, Buzz (Lightyear, that is), "To infinity and beyond!"
