Reason For The Seasons

Reason For The Seasons

Why is the Sun so low in the sky in winter? Why are the days so long in summer? This interactive exhibit won’t lower your air conditioning bill, but it will help you understand why we have seasons.

  • Foucault Pendulum

    Does the Earth really turn? This classic demonstration was the first real proof that it is the Earth that spins, and not the sky.

  • Orbital ATK: NASA Space Launch System

    NASA’s Space Launch System is an advanced, heavy-lift launch vehicle that will provide an entirely new capability for science and human exploration beyond Earth’s orbit. The Space Launch System, or SLS, will carry the Orion Multi-Purpose Crew Vehicle that will carry astronauts, as well as important cargo, equipment and science experi­ments. This 1/72nd scale model and accompanying video show the five-segment twin boosters and launch abort motor built by Orbital ATK here in Utah.

  • International Space Station

    200 miles above the Earth, the largest and most complex space laboratory ever built continues to grow. Continuously inhabited since November, 1997, the scientists aboard the ISS strive to learn more about space, science, and the human body and mind.

  • Newton’s Daydream

    “Newton’s Daydream,” an audio-kinetic sculpture by renowned artist and sculptor George Rhoads, is the newest permanent exhibit at the Clark Planetarium.

    The two-story tall sculpture combines an intricate maze of moving balls with bells, drums and other noisemaking obstacles to create a whirring visual and auditory palette. “Newton’s Daydream” is installed inside the Planetarium’s main lobby and will be the focal point for all visitors.

  • Science on a Sphere

    Clark Planetarium’s newest showcase exhibit, Science On a Sphere (SOS)®, fills the lobby with a global display system. Science on a Sphere uses advance computing systems to project a multitude of video sequences onto a six foot diameter sphere. Image sets include Earth’s weather systems, plate tectonics, ocean temperatures and Earth at night. Also presented are the Milky Way, Sun, Moon and the other planets of our Solar System. Future enhancements will include narrated programs and live demonstrations.

  • The Solar System

    Clark Planetarium’s model of the Solar System is 150 million times smaller than the real thing. Even at this scale, the Sun is so large it cannot be contained fully within the exhibit space! This exhibit has interesting facts about each planet and a computerized quiz that allows you to test your knowledge of the solar system.

  • Weight On Other Worlds

    How much would you weigh if you were standing on Mars? How about on an asteroid, or a Neutron Star, or hovering in a spaceship above the clouds of Jupiter? Weight on Other Worlds will tell you. This great interactive exhibit will both educate and entertain as you watch a computer-animated space alien explore the physical conditions on thirteen different worlds.

  • New Exhibits Coming Soon!

    Clark Planetarium is currently undergoing massive renovations. This means that many of your favorite exhibits may be off the floor or turned off for safety purposes. We know that this can be very frustrating and we thank you for your patience.

    We are working hard towards completion of all-new exhibits galleries for you and your family to enjoy, and are doing so as quickly as possible without closing our doors to the public. We want you to still have access to as much of the planetarium as possible throughout this time.

    Thank you again for your understanding and your patience as we all work together to build a better future for space science education in Utah.
