Astronomy adventurers gathered atop a parking garage at UAA on Tuesday to watch an event that won't pass this way again for more than a century. Through protective glasses and reflective scopes, viewers watched a small dark spot cross in front of the sun. Like a migrating freckle, the silhouette of Venus' transit could be seen specially-equipped telescopes and other devices from 2:06pm to 8:47pm. Sky-gazers came from near and far. Many were content to use dark eyewear and lounge in the sun to spy on our planetary neighbor. Others waited in long lines for a peep through one of telescopes on hand courtesy UAA's physics department. The Sun-Earth-Moon Systems group from the University of North Dakota and an astronomer from the National Autonomous University of Mexico came to Anchorage to take in the spectacle. Alaska and Hawaii are the only two US states able to see the transit in its entirety, according to UAA. The UAA Planetarium also hosted explanatory discussions about the event.
