Thank you, Flagstaff. 💜🌲✨
We’re honored to be named the @azds 2025 Best Northern Arizona Attraction.From packed telescope nights to families discovering the Astronomy Discovery Center for the first time, this community is what makes Lowell… Lowell.

Lowell Observatory is now home to a Moon Tree! 🌳🌕

Earlier this week we celebrated its upcoming planting in a ceremony honoring 65 years of American spaceflight.

Thank you to Senator Kelly, Rosemary Roosa, and everyone who helped make this event truly unforgettable!

Lowell astronomers, with the help of the LDT, continue to be at the forefront of this research and to push the bounds of what we know about these nearby objects. One recent insight highlights a striking, size-dependent trend in the compositions of NEAs.

New year, familiar stars. ✨

January skies shine with bright planets and deep-sky favorites like the Orion Nebula.

Wishing you a season filled with wonder, curiosity, and moments that remind you just how big and beautiful our universe really is.

Happy Holidays from all of us at Lowell Observatory. ❄️✨

[Lowell Observatory @LowellObs]

Watching a child discover something for the first time never gets old. That curiosity is why we built the Astronomy Discovery Center — a place for kids to explore, ask big questions, and grow their sense of wonder.

A little post-holiday magic is on the way. ✨

On Dec 26, the Moon, Saturn, and Neptune bunch up into a rare triple conjunction, a tiny triangle in the sky perfect for binoculars.

If you’re in town, swing by Lowell and we’ll help you spot the trio.

A sweet surprise from asteroid Bennu 🍬🪨

NASA found actual sugars (ribose and glucose) in the OSIRIS-REx samples. Not evidence of life, but a big clue that life’s ingredients were scattered across the early solar system.

Holiday season is here, and so are a few schedule changes.⁠
⁠
Check our updated hours and plan ahead for your next visit to explore the night sky with us. 🫶🏼

If you’re hunting for a gift that isn’t another “thing,” go cosmic. A Lowell Observatory Membership comes with free admission, member events, and a year of night-sky moments. https://t.co/47asCNWsJ0

[Lowell Observatory @LowellObs]

The Geminids are officially active. This year’s conditions are almost perfect, with the Moon out of the way and bright meteors expected all week. The shower runs through the 17, with peak night coming up. Stay tuned for when and how to catch the best show in the sky.

[Lowell Observatory @LowellObs]

The New Moon arrives tomorrow, bringing darker skies and ideal conditions for deep-sky viewing. Andromeda, the Pleiades, and the Hyades are all visible this week.
If you’ve never seen the Milky Way with your own eyes, this is your sign to visit.

For 30 years, Lowell Observatory’s Native American Astronomy Outreach Program has connected the night sky with the stories and traditions of Arizona’s Native Nations. 🌕

Join us Nov. 16 for a special community day of storytelling, music & culture.
