Great five-year video of the sun - level 3
A captivating video has been released by NASA, showing some of the most memorable moments of the sun's activity in the last 5 years.
In honour of NASA’s Solar Dynamics Observatory’s fifth anniversary, NASA released a spectacular five-year time-lapse of the sun.
Highlights include clouds of solar material being hurled into space and loops hovering in the atmosphere, which is known as the corona.
Different colours represent different wavelengths of extreme ultraviolet light, ultraviolet light and visible light which in turn correspond to solar material at different temperatures.
Additionally, SDO returns solar magnetic field data that help scientists study solar activity.
The observatory aims to improve our understanding of the sun's energy and its effects on Earth and near-Earth space.
For this footage, the team captured one frame of the sun every eight hours from June 2010 to February 8th 2015.
