Amazingly beautiful video created by astronomersfrom NASA, using the capabilities of the Solar Dynamics Observatory (SDO) designed to study solar activity. The SDO space orbital station has been continuously observing the Sun for 10 years, photographing it every 0.75 seconds. High-resolution images in the amount of 425 million photos in 10 years amounted to information of 20 million gigabytes of data.
SDO devices allow you to take pictures at 10different ranges of optical waves. The presented video consists of photographs taken by the Atmospheric Imaging Assembly (AIA) at a wavelength of 17.1 nanometers. In this range of ultraviolet waves, we can observe the outer atmospheric layer of our star - the solar corona.
The duration of the video collected from the photos,executed at intervals of one hour, compresses the life history of the Sun over the past 10 years to 61 minutes. When observing a mesmerizing spectacle, one can track the periodic increase and decrease in the activity of the solar corona in accordance with the 11-year cycle of solar activity. The video is accompanied by the soundtrack "Solar Observer" written by musician Lars Leonard.
During viewing, you can observe periodicblackouts caused by the passage of planets between the orbiting observatory and the sun. Also in 2016, the station did not work for a week due to problems with electricity, and a certain shift of the Sun from the center of the frame occurred at the time of calibration of the observatory tools.
