DENVER – The University of Denver will open its Historic Chamberlin Observatory to the public Tuesday for the once- in-a-lifetime viewing of the rare transit of Venus across the sun.
The observatory will be open between 4:00 p.m. and 8:00 p.m.
The next occurrence of this phenomenon is not expected to take place again until 2117.
Safe viewing of the transit will be guided by DU Professor of Astronomy Robert Stencel and the Denver Astronomical Society.
The ‘pinhole projection method’ offers the correct filtering for safe viewing. This simple method can be done by poking a small hole in a paper and projecting the sun’s image onto another blank sheet of paper.
The transit of Venus takes place when the planet Venus passes directly between the Sun and Earth making Venus appear as a small, black disk moving across the face of the sun.
The Historic Chamberlin Observatory at DU is located at 2930 E. Warren Avenue in southeast Denver.
