Great Five-year Video of the Sun – level 3

14-01-2020 15:00

NASA released a captivating time-lapse video showing some of the most memorable moments of the sun’s activity in the last 5 years.

To make the footage, someone captured one frame of the sun every eight hours from June 2010 to February 8th, 2015.

Then NASA released the footage in honour of the Solar Dynamics Observatory’s fifth anniversary. The observatory’s aims are to improve our understanding of the sun’s energy and its effects on Earth and near-Earth space.

Highlights of the footage include clouds of solar material being thrown into space and loops hovering in the atmosphere, which is known as the corona. Different colours in the video represent different wavelengths of extreme ultraviolet light, ultraviolet light and visible light which in turn correspond to solar material at different temperatures.

Difficult words: hover (remain in one place in space), captivating (very interesting), corona (the circle of light around the sun), ultraviolet light (a type of light that is very strong but we cannot see it).

You can watch the video news lower on this page.
