NASA’s Solar Dynamics Observatory shared an amazing time-lapse of the Sun that has been filmed over the course of ten years! What you are about to watch are 425 million high resolution images that have been collected from over a decade of observation from its orbit in space.
With a triad of tools, SDO captures an image of the Sun every 0.75 seconds. The Impression Imaging Assembly (AIA) alone captures images every 12 seconds at 10 different wavelengths of light. This 10-year timeframe showcases photos taken at a wavelength of 17.1 nanometers, which is an extreme ultraviolet wavelength showing the Sun’s outermost atmospheric layer: the corona. By taking a photo every hour, the film condenses a decade of the Sun in 61 minutes. The video shows the rise and fall of activities that occur as part of the 11-year solar cycle of the Sun and notable events, such as planets in transit and eruptions. The personalized music, entitled “Solar Observer”, was composed by the musician Lars Leonhard (https://www.lars-leonhard.de/).
The video lasts more than an hour. I know some of you may not sit around watching it for so long, but if you do, you will see some great sun flares and sunspots. Around 12:23 pm, you can see Venus traveling in front of the sun. I love this stuff and if you do it you will certainly like it too.
