About our planetarium
Built with the new building in 1994, the 30 foot diameter dome of the
UW planetarium provides a unique space in which students can explore
the night sky.
The original building included a Minolta MS-8 starball. The starball
is a precisely constructed
optical/mechanical system that projects an accurate picture of the
night sky as viewed from anywhere on earth.
In 2005, a grad-student led UW Student Tech Fee proposal provided
$90,000 worth of new audio and video equipment to allow for more
dynamic planetarium presentations.
In 2009, we began working with Microsoft's
World Wide Telescope team
to upgrade the planetarium to a fully digital dome system. Completed in
early 2011, this upgrade transformed the dome into an 8-million pixel
digital display. When combined with the World-Wide telescope interface, this
allows for a truly interactive and immersive planetarium experience.
Technical details about the digital upgrade
can be found in this preprint.
