NASA presents a 10-year time-lapse video of the Sun: What are the conditions the Sun has gone through in this period?

 Watch ten years of the Sun performing its duty in this 61-minute-long high-definition time-lapse video. The footage is from NASA's Solar Dynamics Observatory (SDO) which took an image of the Sun every 0.75 seconds from June 1, 2010, to June 1, 2020.

The Solar Dynamics Observatory has been launched from Atlas V rocket on 11 February 2010. After successfully launched it has sent images of the Sun every 0.75 seconds from June 1, 2010. The expense for launching it was 81.7 crores USD.

SDO has assembled 425 million high-resolution images of the Sun, gathering 20 million gigabytes of data over the past 10 years. This data has empowered infinite discoveries about the functioning of our nearest star and how it impacts the solar system.

This 10-year time-lapse showcases photos obtained at a wavelength of 17.1 nanometers, which is an intense ultraviolet wavelength that reveals the Sun’s external atmospheric layer — the corona. Compiling one photo every hour, the video summarizes a decade of the Sun into 61 minutes. The video presents the rise and fall in the activity that happens as part of the Sun’s 11-year solar cycle and important events, like transiting planets and explosions.
