    Join us on March 28, 2014 at 7:00 p.m., Hagar Auditorium at the Museum of the Rockies to hear Dr. Sarah Jaeggli from MSU, Solar Physics Postdoctoral Researcher, her talk will be an IRIS mission update.

    The Interface Region Imaging Spectrograph (IRIS) is a new mission to look at the Sun which was launched June 27, 2013.  IRIS was designed to look at a very mysterious region above the Sun’s visible surface where the very hot gas of the corona (1 million degrees Celsius) meets the very cool gas of the chromosphere (5000 degrees Celsius).  The mystery lies in how the Sun maintains the chromosphere at such a cool temperature while transferring energy through it into the hot corona.  The MSU solar physics group is part of the international team responsible for building  the instrument, operating it, and analyzing the images it sends back to Earth.  In this lecture she’ll give an update on the IRIS mission and talk  about the new science that is being done at MSU.
