Astronomers will announce major findings about planets outside our solar system, known as extrasolar planets, at a NASA Science Update at 1 p.m. EST, Wednesday, March 23.

The Update is in the Webb Auditorium, NASA Headquarters, 300 E St., SW, Washington. NASA TV will carry the Update live. Reporters may watch the briefing at participating NASA centers. The discoveries were made by NASA’s Spitzer Space Telescope, when researchers discovered new capabilities of the infrared instrument to search for the planets.
