This image shows views of the Sun and the Earth at two different time periods in history. Going from left to right, top to bottom, you see the Sun as depicted by the Anasazi around 1000 A.D., the Sun as seen from a satellite in modern times, the Earth as Islamic artists depicted it around 1000 A.D., and the Earth as viewed from Apollo 11 about 35 years ago.

March 20, 2005 is the Vernal Equinox (the "first day" of Spring in the Northern Hemisphere or the "first day" of Fall in the Southern Hemisphere). It is also Sun-Earth Day! Sun-Earth Day is a celebration of the Sun, the space around the Earth (geospace), and how all of it affects life on our planet. In classrooms, museums, planetariums, and at NASA centers, we plan to have a blast sharing stories, images, and activities related to the Sun-Earth connections in our Solar System.

NASA’s Sun-Earth Connection Education Forum provides lots of information about Sun-Earth Day. This year NASA's theme for Sun-Earth Day is "Ancient Observatories: Timeless Knowledge", which provides a look at observations of the Sun by many different cultures throughout history.
