What’s our place in the universe? Can you “hear” gravity? Two new shows at Bays Mountain Park & Planetarium answer these questions and more this November.

The new alternate feature, “Under the Milky Way,” begins on November 2 and highlights our very own Milky Way galaxy. Learn about the structure of our galaxy and how it was formed, and take a look at our continuing understanding of what our galaxy is and how large it is.

The show’s second feature is a live presentation utilizing some of the wonderful capabilities of our Carl Zeiss ZKP-4 star projector, as well as our digital projection system. Viewers will see our current night sky and learn how we fit into the Milky Way. The program concludes by transforming our position on earth and travel down to the southern hemisphere and spy the two largest dwarf galaxies that orbit us, the Magellanic Clouds. “Under the Milky Way” runs for about 35 minutes.

“Einstein’s Gravity Playlist,” the new main feature, premiers on November 12. 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.
