NASA's Solar Dynamics Observatory, a space telescope charged with watching the sun in unprecedented detail, revealed its first look at the sun to the world one year ago today.
Since then, the telescope has watched the sun shift from its quietest period in years to the beginning of a new, active solar cycle. It's seen loops of plasma that dwarf the Earth tracing the sun's magnetic field, early stages of massive explosions that send hot charged material ripping through space, and sunspots dancing across the solar surface.
