CU-BOULDER to observe transit of Venus
Start Date: 6/5/2012Start Time: 3:30 PM
End Date: 6/5/2012End Time: 4:00 PM
Event Description:
Join the University of Colorado Boulder for a rare opportunity to witness Venus crossing directly between the Earth and the sun. Fiske Planetarium and the Sommers-Bausch Observatory will provide live presentations and web feeds of this rare astronomical event, along with many space-science activities. The events are free and open to the public and will include telescopes to safely observe the sun, activities for kids and talks by astronomers and local space scientists.

This will be the last time in the 21st century to see Venus travel across the face of the sun. Transits of Venus occur in pairs, and the first of the next pair will occur in 2117 - more than 100 years from now.

Sommers-Bausch Observatory will have telescopes pointed sunward to enable visitors to safely watch the progress of the Venus transit. Hosts will be on hand to answer questions, and include members of the Boulder Astronomy and Space Society and the CU-Boulder Department of Astrophysical & Planetary Sciences.

Fiske Planetarium opens the theatre at 3:30 p.m. for the Sommers-Bausch Observatory live broadcast of the transit. Scientists from the Department of Astrophysical and Planetary Sciences and Ball Aerospace will give talks beginning at 4:45 p.m. Hands-on activities include a Kepler Spacecraft model and a Lego Orrery system that explains how the Kepler spacecraft finds planets.

Sommers-Bausch Observatory will broadcast three live Ustream video channels of the transit from noon until sunset; go to http://cosmos.colorado.edu/sbo/public/transit_live.html for internet coverage. One channel will show the transit against the visible sunspots of the solar photosphere; another will show the Venus passage in front of the loops, prominences, filaments and possibly flares of the chromosphere, or outer atmosphere of the Sun.

  • Everyone
  • Ticket information:
    Free and open to the public.
    Of note:
    SAFETY TIP: It is never safe to look directly at the sun. The only way to see the transit of Venus safely is to use special equipment. The eclipse-watching glasses used for the May partial solar eclipse can also be used to observe the transit. Watch online or visit one of the local viewing activities and celebrate this rare event that helps us find our place in space.
