This image is a composite of 25 separate images spanning the period of April 16, 2012, to April 15, 2013. It uses the SDO AIA wavelength of 171 angstroms and reveals the zones on the sun where active regions are most common during this part of the solar cycle.

Since the Solar Dynamics Observatory opened its multi-spectral eyes in space about three years ago, we’ve posted numerous videos and images from the mission, showing incredible views of our dynamic Sun. Scott Wiessinger from Goddard Space Flight Center’s Space Visualization Studio has put together great timelapse compilation of images from the past three years, as well as a one composite still image to “try to encapsulate a timelapse into one static graphic,” he told us via email. “I blended 25 stills from over the last year, and it’s interesting to see the bright bands of active regions.” Scott said he was fascinated by seeing the views of the Sun over a long range of time.
