A new time lapse released by NASA shows 10 years of images of the Sun, 425 million of them, to be exact. Condensed into a time span, the one-hour video consists of a photo of the Sun every day between June 2, 2010 and June 2, 2020.
Properly titled “A Decade of Sun”, the finished product is the result of images taken by the Solar Dynamics Observatory (SDO) over the past decade.
NASA said:
From its orbit in space around Earth, SDO has collected 425 million high-resolution images of the Sun, accumulating 20 million gigabytes of data in the past 10 years. Compiling one photo every hour, the film condenses a decade of the Sun into 61 minutes. The video shows the rise and fall of activity that occurs as part of the Sun’s 11-year solar cycle and notable events such as transiting planets and eruptions.
One sensation you’ll also see in the clip are the significantly dark frames, which NASA says are caused by Earth or the Moon that outshines the SDO as they move between the orbiting spacecraft and the Sun. At least, in their Most; There is one instance where a glitch removed power for an entire week in 2016, while NASA hastened to fix it.
Experience the entire time span above. The NASA website also provides a more detailed description of the technology used by SDO to capture the images.
