NASA has released a video of observations of solar weather and flares using space
The Solar Dynamics Observatory takes a picturethe star closest to Earth every 0.75 s. The photographs used to create the video were obtained by observing electromagnetic waves with a wavelength of 17.1 nm. This is the extreme ultraviolet that corresponds to the solar corona, the outer atmosphere of the star.

The video shows bright active areas of incandescentplasma moving on the surface of the Sun while it rotates around its axis. Recall that one revolution of the Sun is about 27 Earth days. Plasma loops are visible above the active regions, which are formed by the magnetic field of the star.
"These bright regions are the source of solar flares, which form when magnetic fields join together in a process called magnetic reconnection," they wroteSpace Agency researchers in the description of the video.
According to NASA, the Solar ObservatoryThe speakers work continuously, but you can still see a “black screen” on the video. Such moments are associated with eclipses from the Earth and the Moon, when our planet and its natural satellite passed between the observatory spacecraft and the Sun.
