As of June 2020, NASA\u2019s Solar Dynamics Observatory \u2013 SDO \u2013 has now been watching the Sun non-stop for over a full decade. From its orbit in space around Earth, SDO has gathered 425 million high-resolution images of the Sun, amassing 20 million gigabytes of data over the past 10 years. This information has enabled countless new discoveries about the workings of our closest star and how it influences the solar system.<\/p>\n

With a triad of instruments, SDO captures an image of the Sun every 0.75 seconds. The Atmospheric Imaging Assembly (AIA) instrument alone captures images every 12 seconds at 10 different wavelengths of light. This 10-year time lapse showcases photos taken at a wavelength of 17.1 nanometers, which is an extreme ultraviolet wavelength that shows the Sun\u2019s outermost atmospheric layer \u2013 the corona. Compiling one photo every hour, the movie condenses a decade of the Sun into 61 minutes. The video shows the rise and fall in activity that occurs as part of the Sun\u2019s 11-year solar cycle and notable events, like transiting planets and eruptions. The custom music, titled \u201cSolar Observer,\u201d was composed by musician Lars Leonhard.<\/p><\/blockquote>\n
