What’s that constellation you saw last night? Can you “hear” gravity? Our current planetarium features can answer these questions and more!

“Einstein’s Gravity Playlist” is our main feature through March. This program explores the ripples in space-time known as gravitational waves. Albert Einstein first predicted the existence of gravitational waves in 1916, and a century later, scientists detected these waves using incredibly precise laser technology here on Earth. In honor of this long-anticipated detection, the scientists who created the Laser Interferometer Gravitational-Wave Observatory (LIGO) won the Nobel Prize in Physics in 2017. In this show, viewers follow Lucia, a PhD student in physics, on an exploration of how gravitational waves are formed, how they move through the Universe, and how scientists like her work to hear them.

“Einstein’s Gravity Playlist” was created through a collaboration between Montana State University’s eXtreme Gravity Institute, the Department of Physics, the School of Film and Photography, and the School of Music. The runtime is about 35 minutes.

Our alternate feature for January and February highlights our local view of the night sky. “Appalachian Skies – Winter” will take visitors on a majestic tour of the evening sky using the spectacular Carl Zeiss ZKP-4 star projector instrument. Its fiber-optic generated star field is stunning and a pleasure to see. You don’t want to miss it!

Produced in house and led by planetarium staff, “Appalachian Skies” will show you what fascinating constellations are easily visible in your own backyard. Marvel at their ancient lore. Find out what planets are easily seen as well. Visitors will take this knowledge home and be able to locate these sights for themselves.
