NASA plans Webcast about the sun

NASA scientists will reveal new information and images about the Earth’s sun and its influence on the solar system during a Webcast March 20 at 1 p.m. Eastern Daylight Time.

The Webcast will honor Sun-Earth Day, observed in conjunction with the spring equinox, and will emphasize daytime astronomy, NASA officials said.

"Tremendous strides have been made with satellite and ground-based observations of the sun, which have enabled us to monitor the sun to gain a better understanding of the processes that govern its influence on our solar system," said Eric Christian, a scientist at NASA's Goddard Space Flight Center in Greenbelt, Md.

NASA uses celestial events to engage the public through Webcasts, podcasts, space science activities, demonstrations and interactions with scientists, NASA officials said.

The Goddard center is producing the Sun-Earth Day Webcast, and NASA's Jet Propulsion Laboratory in Pasadena, Calif., and the Adler Planetarium in Chicago are participating in it. NASA Television and the agency's Web site will broadcast the event live.
