Some of the Denver Astronomical Society's brightest and most enthusiastic individuals lead Public Nights each Tuesday and Thursday at DU's Historic Chamberlin Observatory. Public Nights are a Denver tradition that began on the night of August 1, 1894. The Denver Astronomical Society has hosted Public Nights for over 50 years.

All public nights start with an informative, multi-media astronomy presentation by a DAS lecturer. Presentations are illustrated with colorful computer graphics shows, videos, and/or whatever audio/visual method is appropriate. Astronomy presentations are designed for visitors of all ages.

Additionally, visitors will be treated to telescopic views of the moon, stars and star clusters, planets, galaxies, nebulae, etc., through Chamberlin's historic, 28-foot long, 20-inch aperture Alvan Clark-Saegmuller refracting telescope (weather permitting).

These shows are specifically tailored for the non-astronomer who is interested in learning about the universe and how to observe celestial objects. Bring the whole family!

Admission prices are only $2 for children and $3 for adults, payable at the observatory. Please sign up on the online reservation system.
