The Science History Institute Museum is closed for renovations.
The Othmer Library remains open by appointment.

Embark on a cosmic journey with us this First Friday, as we delve into the mesmerizing realms of astronomy and space—and the captivating history of our cosmic understanding.

Join our celestial celebration and discover the “spheres of influence,” where planets, orbits, stars, and moons collide with the forces of gravity, societal pressures, norms, and education. Witness captivating science spectacles that have shaped our understanding of the universe—and meet the people behind these famous experiments that have left an indelible mark on the history of astronomy. 

Immerse yourself in the tools of the trade with a hands-on collection featuring spectroscopes, telescopes, diffraction glasses, and unique celestial globes, astrolabes, and armillary globes. Touch, feel, and discover the instruments that paved the way for celestial revelations. And hear from a LightSound device, which converts light into sound so that blindness is no longer a barrier to the experience of astronomy.

You’ll also explore star charts, marginalia, and more in our historical library collections related to revolutionary advancements in astronomy.

Engage your creative side as you craft your personalized star charts. What celestial wonders will you map in the night sky? The possibilities are as vast as the cosmos itself! And don’t forget to take home a special gift: your very own solar eclipse glasses!

Be prepared for the celestial event of the season. Join us as we gear up for the solar eclipse on Monday, April 8, and witness the cosmic dance in the sky. 

Don’t miss this stellar experience!
