Three Years Of Solar Activity In Three Minutes – Nasa Timelapse



” Nasa has created a time-lapse video of images of sun taken over past three years as it heads towards the peak of solar activity in its 11-year cycle.


During the course of the video, the sun subtly increases and decreases in apparent size. This is because the distance between the SDO spacecraft and the sun varies over time.


These images have regularly caught solar flares and coronal mass ejections in the act, types of space weather that can send radiation and solar material toward Earth and interfere with satellites in space.”
