NASA will host a news conference at 8 a.m. PDT (11 a.m. EDT) Thursday, March 21, to discuss the first cosmology results from Planck, a European Space Agency mission with significant NASA participation.

The briefing will be held at NASA Headquarters in Washington. It will be broadcast live on NASA Television and streamed on the agency’s website.

Planck launched into space in 2009 and has been scanning the skies ever since, mapping cosmic microwave background, or the afterglow, of the big bang that created our universe more than 13 billion years ago.

The briefing participants are:

— Paul Hertz, director of astrophysics, NASA, Washington

— Charles Lawrence, U.S. Planck project scientist, NASA’s Jet Propulsion Laboratory (JPL), Pasadena, Calif.

— Martin White, U.S. Planck scientist, University of California, Berkeley, Calif.

— Krzysztof Gorski, U.S. Planck scientist, JPL

— Marc Kamionkowski, professor of physics and astronomy, John Hopkins University, Baltimore, Md.
