The Steele Visitor Center at Lowell Observatory

PROGRAMMING ALERT: The Clark Telescope is closed for renovation through mid-2015. Daytime Mars Tours will still go inside the dome when possible. In the evening, we will use the recently renovated 16-inch McAllister Telescope as our primary telescope for public viewing.

Programming subject to change due to weather conditions, special events, etc.

Daytime guided tours

Take the Mars Tour at 1 p.m. and 3 p.m. and explore our historic Rotunda Library.

Join the Pluto Tour at 2 p.m. and 4 p.m. and see the Pluto Discovery Telescope.

Solar viewing

Every day from 12 to 12:45 p.m., view the Sun through a specially equipped solar telescope.

On cloudy days when we can't offer solar viewing, we'll play an indoor program highlighting dramatic features of the sun.

Evening Multimedia shows

5, 6, 7, and 8 p.m. Scanning the Skies: The Discovery Channel Telescope. This 42-minute Discovery Channel special documents the construction of Lowell's cutting-edge, world-class telescope from conception to "first light" in 2012.

Enjoy SlipherVision, our immersive space theater. Embark on a journey through the cosmos and learn to navigate your way around the night sky.

Cosmic Zoom at 5 and 7 p.m. Cosmic Zoom reveals our place in the Universe. Beginning with Sun we travel through the Solar System to the outer planets, past our neighboring stars, breaking free from our own Galaxy, and finally ending at the edge of the known Universe. This is a great opportunity for learners of all levels to ask questions about anything in the cosmos!

Sky Tonight at 6 and 8 p.m. Join us for a tour of the current night sky. This ever-changing program explores the season's constellations, bright stars, visible planets, deep sky objects and celestial highlights. This presentation also features constellation mythology and recent space news. This is a great program for anyone looking to become better acquainted with the night sky.

In the evening

We'll open up the telescopes (weather permitting) and view planets, the moon, star cluster, and more, all with the assistance of our educators. Enjoy SlipherVision, our new immersive space theater.
