18 September 2026 | Family Weekend at the Bucknell Observatory

The Bucknell Observatory will be open for observatory tours on Friday, September 18th, as part of the Family Weekend events. The Physics and Astronomy department at Bucknell invites our campus visitors to join us at the on-campus Observatory for tours, telescope viewings, and night sky presentations, weather permitting.

The event is free, although visitors must pre-register through the Family Weekend website.

In the event of clouds, rain, or other sky-obscuring weather, we will still hold the event, though our telescope observing time may be limited.

Date: Friday, 18 September 2026

Time: Tours at 8:30 and 9:30pm

Location: the Bucknell Observatory

Remember!

  • This corner of campus will be dark, as we turn off as many lights as we can. Lights off means the event is happening, so don’t get confused!
  • No flashlights, please! To better see the stars, everyone’s eyes need to adapt to the dark. We’ll provide some red lights which won’t interfere with night vision. (If you must bring your phone, please turn on the screen’s adaptive brightness settings.)
  • We have a limited capacity for our tours. If this date has filled, please look out for our next public night!

10 February 2024 | Family Night at the Bucknell Observatory

Come enjoy the sights of the night sky on Saturday, 10 February at the Bucknell Observatory for Family Night 2024. Bucknell astronomers and students will help observers see the Moon, planets, the Great Nebula in Orion, and other celestial sights through the Observatory’s telescopes.

Local Grammy-nominated artist Billy Kelly will sing songs of the stars for kids of all ages several times during the evening, and Brian Garthwaite of the Bucknell Physics & Astronomy department will present a family-friendly talk “Jupiter, the King of Planets.” Children can build a “Jupiter mobile” craft to take home.

The telescopes, including the 1887 Alvin Clark refractor and the modern telescopes of the Isaac J. Tressler Observing Lab, will be open for observing throughout the evening (weather permitting). Bucknell University students and staff will be on hand to assist with the observing and point out constellations.

This is a free open house event. All activities will be available throughout the evening, so drop in anytime between 6:30 and 9:30 pm.
