Sun-Earth Day 2005
News story originally written on March 18, 2005
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.
Please see the links below for more information on how to participate in Sun-Earth
Day.
