Description

The Solar Dynamics Observatory (SDO) has been hailed as the "Hubble Space Telescope for heliophysics"—a state-of-the-art spacecraft that will observe our nearest star with unprecedented detail. Its first images reveal two solar events that burst into view just after SDO's telescope array, called the Atmospheric Image Assembly (AIA), readied for operations on March 30, 2010. In this Science Bulletins snapshot, watch a prominence and a solar flare like you've never seen them before, and learn how the spacecraft will help scientists understand the Sun, its connection to our planet, and the Universe at large.
