It has been ten years since NASA launched a technical satellite to film the surface of the sunlight –and they have now released a gorgeous time-lapse video of its solar moves within the course of the decade.
The Solar Dynamic Observatory (SDO) has been taking high-resolution photos of the sun every 0. 75 moments since it was launched into Earth’s orbit back in June 2010.
To date, the SDO has collected more than 425 million images of the sun in 10 distinct wavelengths of light, totaling around 20 million gigabytes of photos.
So as a means of celebrating the SDO’s 10th anniversary in the end of June, NASA chosen 87,000 of the satellite photographs and steered them into a time lapse view of the sun’s surface, with every minute of the movie reflects one day on Earth.
According to the NASA movie caption, every one the photos were”shot at a wavelength of 17.1 nanometers, which is an intense ultraviolet wavelength that shows the sun’s outermost atmospheric layer–the corona.”
“Compiling one photo every hour, the movie condenses a decade of the Sun to 61 minutes,” the caption persists. “While SDO has kept an unblinking eye pointed towards the Sun, there have been a few moments it missed. As they pass between the spacecraft and the Sun, Earth or the Moon eclipsing SDO causes the dark frames from the movie. A longer conclusion in 2016 was caused by a temporary issue with the AIA tool that was solved after a week. The pictures where the Sun is off-center were observed when SDO was calibrating its tools.”
“SDO and other NASA missions will continue to see our Sun in the years to come, providing additional insights about our place in space and information to keep our astronauts and assets safe.”
