NASA’s Solar Dynamics Observatory (SDO) is celebrating its 10th birthday and to commemorate, NASA has released a timelapse of the past 10 years of pictures from June 2, 2010 to June 1, 2020.
The timelapse uses one photo for each hour for the last 10 years. All told, each day takes one second in the video, so the one hour video is remarkably detailed. It is truly mesmerising to watch.
SDO captures an image of the sun every 0.75 seconds at 10 different wavelengths. According to a NASA statement, the SDO has taken 425 million high-resolution images over the last 10 years, covering 20 million gigabytes of data.
Occasionally, you will see the image glitch when the Earth or the Moon obstruct the view for a few frames, or when the spacecraft is recalibrating, but this platform has deepened our understanding about the sun and how it influences us and the solar system.
