A coronagraph, which is a specialized astronomic instrument that allows scientists to block out the direct light from our Sun in order to study the Sun's coronaOur Sun constantly emits solar radiation, which causes space weather and space climate.  The effects of this can be as beautiful as aurora and as damaging as power outages.  Explore the resources below to learn more!


Animation: 2017 North American Solar Eclipse

On August 21, 2017, a total solar eclipse was visible across the contiguous United States, dubbed the "Great American Eclipse."  Learn how the High Altitude Observatory at NCAR has been studying eclipses and the Sun's corona since the coronagraph was invented in the 1930s.  A coronagraph, like the one pictured above which is on display at the NCAR Mesa Lab, is a type of attachment you can put on a telescope in order to block out the direct light from stars so that nearby objects can be seen.
