NASA does that again. In a jaw-dropping release, the space agency has captured 10-years of our Sun in 61-minutes footage.
The release comes after NASA’s Solar Dynamics Observatory – SDO – completed a decade of capturing the Sun in June 2020. For a decade, the SDO that orbits around the earth has captured one image of the Sun, every 0.75 seconds, amassing 425 million high-resolution images worth 20 million gigabytes of data.
The 10-year timelapse is made from images of the ball of hot plasma captured from ten different wavelengths of light.
In simple terms, you must know that every second of the 61-min long video you watch, you actually see all the images captured in one earth-day. The images also included the ones taken by the Atmospheric Imaging Assembly (AIA) that captures the Sun “every 12 seconds at 10 different wavelengths of light”.
In the video, however, only the images captured at 17.1 nanometres wavelength were used “which is an extreme ultraviolet wavelength that shows the Sun’s outermost atmospheric layer – the corona.”
For such a grand presentation, NASA commissioned German musician Lars Leonhard to compose the exclusive Solar Observe music to go with the video.
“While SDO has kept an unblinking eye pointed toward the Sun, there have been a few moments it missed,” NASA says in a statement with the release, referring to the dark frames in the video that was “caused by Earth or the Moon eclipsing SDO as they pass between the spacecraft and the Sun.”
There is also another longer blackout that happened in 2016 because of a temporary issue with the AIA instrument that was restored to normalcy within a week.
