Flagstaff, Ariz. — Lowell Observatory will host a special viewing event for the Transit of Venus on Tuesday, June 5th. At 2 p.m., join author and science historian William Sheehan for an indoor presentation about this unusual and fascinating celestial event. A transit takes place when Venus passes between the Sun and Earth, making it possible for us to see the small dark disk of Venus against the bright disk of the Sun.

Later, we will have specially filtered telescopes to allow you to safely view the shadow of Venus passing over the Sun. The Transit starts at about 3:05 p.m. and viewing will continue until the Sun passes behind trees. The Starry Skies Shop at Lowell currently has 2,000 solar glasses for sale.

Later, enjoy exciting multimedia programs and view other breathtaking objects through telescopes.

Mr. Sheehan will also discuss the Transit at a talk titled “Here Comes the Transit!,” which will take place Monday, June 4th at 7 p.m.

Venus transits occur in pairs eight-years apart; pairs are separated by more than a century, making Venus transits among the rarest of planetary alignments. Next week’s Transit is the first since June 8, 2004 and the next pair of Venus transits will occur more than a century from now on December 11, 2117 and December 8, 2125.

These events are co-sponsored by the Coconino Astronomical Society.

About Lowell Observatory
Lowell Observatory is a private, non-profit research institution founded in 1894 by Percival Lowell. The Observatory has been the site of many important findings including the discovery of the large recessional velocities (redshift) of galaxies by Vesto Slipher in 1912-1914 (a result that led ultimately to the realization the universe is expanding), and the discovery of Pluto by Clyde Tombaugh in 1930. Today, Lowell’s 22 astronomers use ground-based telescopes around the world, telescopes in space, and NASA planetary spacecraft to conduct research in diverse areas of astronomy and planetary science. The Observatory welcomes about 80,000 visitors each year to its Mars Hill campus in Flagstaff, Arizona for a variety of tours, telescope viewing, and special programs. Lowell Observatory currently has four research telescopes at its Anderson Mesa dark sky site east of Flagstaff, and is testing and commissioning a 4-meter class research telescope, the Discovery Channel Telescope.
