Black Holes

Thursday, September 7, 2023 7:00 pm

There's a place from which nothing escapes, not even light, where time and space literally come to end. It's at this point, inside this fantastic riddle, that black holes exert their sway over the cosmos … and our imaginations.   Travel to a place where the laws of energy, force, motion, and time are pushed to the limit.  Experience one of the most exciting applications of astronomy, mathematics, and physics in an immersive experience like no other.  Zip through other-worldly wormholes, experience the creation of the Milky Way Galaxy, and witness the violent death of a star and subsequent birth of a black hole. Mathematical equations, cutting-edge science, and Einstein's theories fill in holes along the way, providing the most complete picture yet on this mysterious phenomenon. Can you feel the pull?   Prior to the show, we'll tour the seasonal stars, planets and constellations of the night sky.   Tickets

Enjoy a front-row seat as you experience an unprecedented 1,001-day expedition, encountering the challenges and adventure of space travel.  After spending nearly seven months navigating to Mars, the crew successfully lands and conducts a number of experiments to learn if life on Mars is a possibility before splashing down and welcomed home by an elated planet Earth.    Join us to experience this visual spectacle, going inside the spaceship as it traverses the universe. Witness the effects of artificial gravity on the crew and even dodge a solar storm that threatens the expedition’s trek towards Mars.   Prior to the show, we'll tour the seasonal stars, planets and constellations of the night sky.  Tickets

Space Opera w Ops 32 "The Planets"

Thursday, November 9, 2023 7:00 pm

The discovery of a flying disc beneath the earth allows passengers to take off from the Earth and visit an entire solar system. The ambient recreates the interior of an alien spaceship where a voice facilitates the journey and provides information on each galactic stop.   SpaceOpera is therefore an artistic, philosophic, scientific and cinematic experience all at the same time and indeed a unique experience of its kind.  The journey in SpaceOpera is designed and harmonized entirely with Gustav Holst’s The Planets, Op. 32, which is one of his most beloved and admired works.   Prior to the show, we'll tour the seasonal stars, planets and constellations of the night sky. 

Dinosaurs at Dusk

Thursday, December 7, 2023 7:00 pm

Travel back in time through the Triassic, Jurassic and Cretaceous geological periods in search of the ancestors of modern-day birds, the feathered dinosaurs. Join a father and his teenage daughter Lucy, who share a fascination for all things that fly, as they travel back in time navigating from continent to continent, exploring an Earth teeming with dinosaurs in search for clues on the origins of flight.  Racing against time, they paraglide through ancient skies with Quetzalcoatlus, flee from raptors and traverse deserts with Argentinosaurus. They walk through rain forests, climb ice cliffs, sail over primordial seas and parachute into a huge sinkhole in their search for the first flying birds. When time runs out they even experience first-hand the cataclysmic ‘final day' of the dinosaurs.  Prior to the show, we'll tour the seasonal stars, planets and constellations of the night sky.
