As children, we were told not to stare (or even watch directly) the sun because it could hurt our eyes. Sure, that makes sense, but it also contributes to the secret of the sun. We know it’s light, but how exactly does it look? Thanks to NASA, it’s no wonder that they recently released one 10 years timelapse video from the sun. Here’s how you see it and what you’ll see.
What’s in the video
At this point, NASA’s Solar Dynamics Observatory (SDO) has been watching the sun for more than a decade. especially since June 2, 2010. After reaching their 10-year mark on June 1, 2020, the SDO put together this time-lapse video that shows what happened on our next star.
Over the past ten years, SDO has collected 425 million high-resolution sun images, or one image every 0.75 seconds. This resulted in an hourly photo of the sun. For the time-lapse video, each day was combined into one second of footage so that it was 61 minutes long.
What exactly do you see According to NASA, “the video shows the increase and decrease in activity that occurs as part of the Sun’s 11-year solar cycle, as well as notable events such as the transit of planets and eruptions.” The video also includes custom music titled “Solar Observer” composed by musician Lars Leonhard.

Was there anything the video missed? Via NASA::
While SDO kept a blink-free eye on the sun, it missed a few moments. The dark images in the video are caused by the Earth or Moon dwarfing SDO when they move between the spaceship and the sun. A prolonged power outage in 2016 was caused by a temporary problem with the AEI instrument that was successfully resolved after a week. The images where the sun is off-center were observed when SDO calibrated its instruments.
How to watch
NASA provided the video on Youtubeso everyone can see it from the comfort of their own home:
