Viewing The Transit See our spectacular image galleries of the recent ‘ Transit of Venus’ as witnessed by the public and our participating observatories!	John Philip Sousa (1854-1932) was very interested in the 1882 transit of Venus. In 1882-3 he wrote his 'Venus Transit March'. Visit this special section of our website where you can view the cover page of the 1889 sheet music, play the march on your piano, or listen to two complete versions of this enticing score!
In the News... On June 8th, 2004 a celestial event of historical scientific importance will occur when the silhouette of the planet Venus once again crosses the face of the Sun as seen from the Earth. This event or transit of Venus last occurred in 1882, so no one alive today has ever witnessed the transit of Venus	For detailed maps and transit times for hundreds of cities, visit NASA's "Prediction's for the 2004 Transit of Venus" web page.
The Venus Transit Animation begins at the surface of Venus where heat ripples distort the scene in a shimmering heat bath. As we leave Venus and move off into space, we arrive at Earth and watch as Venus falls behind us and finally passes across the face of the Sun.	The Reanimating the 1882 Transit of Venus Article will explain astronomer David Peck Todd's observation of the Transit of Venus in 1882. Todd's 147 surviving photos have been converted into a 4.0 MB Movie, and a 1.2 MB Movie which help to illustrate the event.
Most people, when they think of a "planet", imagine a large roundish body with a rocky surface and an atmosphere. Forgetting Pluto for a moment (which has too many issues to deal with here), only Venus, Earth, and Mars share these characteristics as planets in our solar system. Learn more in our " VENUS, EARTH, and MARS" comparison website!	Are you Ready for Sun-Earth Day 2005? We will feature both ancient and modern observatories from around the world. Educators will benefit from teacher guides, activities, and a wealth of information. We will also have areas specifically tailored for students, scientists, museums, and amateur astronomer participation.

Sun-Earth Day 2004 has selected the transit of Venus as this year's theme. Opportunities are available to prepare for the viewing of the event. This website has been developed to provide the necessary resources and opportunities for participation in our fourth Sun-Earth Day. This year's program will continue to offer new and exciting space science content that will cross all of space sciences, offering activities and resources for every classroom and museums event. The goal is to involve as much of the student population and the public in this event as possible and to help them understand the immense importance and excitement surrounding this and previous transits.

Through engaging activities focused on US and world history, music, technology, math, and astronomy, classrooms and museums can create their own event or participate in one of the opportunities we make available. Comparisons of Venus with Earth and Mars, calculations of the distances to nearby stars, and the use of transits to identify extra-solar planets will all add to the excitement of this cosmic occurrence.
