Transit of Venus Viewing Locations in Maryland
2012 Event is Tuesday evening -- next viewing 2117.
Want to see a once-in-a-lifetime celestial event?
There are locations across Maryland hosting viewing parties for the Transit of Venus across the face of the Sun, a rare astronomical occurrence that will begin at 6:03 p.m. Tuesday in the Baltimore area.
Often referred to as the "Evening Star" or "Morning Star," Venus is the brightest natural object in our sky after the Sun and the Moon. As the second planet from the Sun, it's closer to the Sun than the Earth is.
A "transit" occurs when Venus passes between Earth and the Sun in such a way that Venus's silhouette is backlit by the Sun's brilliant light. It last happened in 2004, and won't happen again until 2117.
“It’s a very exciting event, and since our rain date is 2117, this is the last time [to see the Transit of Venus] in a lifetime,” said Joel Goodman, a dentist from Glenelg who also is the observatory chair of the Howard Astronomical League.
Here is a selection of places in Maryland offering viewing parties for the event.

A word of caution: remember, don't look directly at the Sun.
Experts suggest that one widely available filter for safe solar viewing is Number 14 welder's glass. If you're using a telescope, be sure it has a solar filter.
Pinhole projectors, though a good way to observe the sun safely, suffer from shortcomings when Venus approaches the edges of the Sun. Small features like the halo around Venus will not likely be discernible.
