Breathtaking video: 3 years of Sun activity

The US Aerospace Agency (NASA) has just released an impressive video of the Sun's activity over the past 3 years but condensed time in just 3 minutes.

The video was made possible by images collected and transferred to Earth by NASA's Solar Dynamics Observatory (SDO) since it was launched into orbit in 2010. It has shown huge explosions and eruptions. The Sun's unprecedented detail.

Images of SDO satellites also reveal the weather in space, which can emit the Sun's radiation and materials to Earth and hinder satellites in space.

In 3 years of operation, SDO satellites have not been interrupted in monitoring and recording the rising image of the Sun to the peak of a strong operation in a normal cycle lasting 11 years. SDO's ultra-sensitive cameras photographed the Sun every 12 seconds at 10 different wavelengths.

The condensed time video shows the 3-year continuous operation of the Sun at a rate of 2 images per day, mainly based on the 171 Angstroms wavelength. Each image is displayed for two frames at a frame rate of 29.97. At the chosen wavelength, we can easily see how the Sun's 25-day rotation cycle as well as how the star's activity increased during the three-year survey.

During the duration of the video, the Sun seems to have increased and decreased in size. This phenomenon stems from a change in the distance between SDO and the Sun over time.
