CALENDAR ITEM
Fiske Planetarium at the University of Colorado at Boulder will explore the dynamics of the solar system and the way it was shaped by millions of collisions during "Cosmic Collisions and Our Solar System," Friday, Sept. 22, at 7:30 p.m. at the planetarium.
The pre-recorded show travels back in time to the beginning of the solar system when devastating impacts of asteroids, comets and millions of chunks of floating debris constantly reworked the surfaces of the planets.
The show also examines the chances that a dangerous asteroid or comet will hit Earth and what would happen to life on the planet if it were hit.
Tickets are $4 for adults and $3 for seniors and children and go on sale at 7 p.m. the night of the show. Fiske Planetarium is located at Regent Drive and Kittredge Loop Drive on the CU-Boulder campus.
