NASA showed the ever-changing surface of the Sun with a time-lapse that spans 133 days, according to Space.
An hour-long video shows what happened to the Sun over four months &ndash ; from August 12 to December 22, 2022.
NASA's Solar Dynamics Observatory (SDO) captured the video as part of its ongoing monitoring of solar flares and other space weather.
“This 133-day time-lapse shows photographs taken at a wavelength of 17.1 nanometers , which is the extreme ultraviolet wavelength that represents the outermost atmospheric layer of the Sun – crown", – reads the description below the video.
The video also shows bright, active regions of superhot plasma spilling over the Sun's surface as it rotates on its axis, making one complete rotation every 27 Earth days.
“The loops extending over bright regions are magnetic fields that have trapped hot plasma. These bright regions are also the source of solar flares, which appear as bright flashes when magnetic fields combine in a process called magnetic reconnection” ;, – say NASA.
You can see some of the dark moments of the video. They were caused by eclipses of the Earth and the Moon.
