Nasa has released an incredible time-lapse video showing some of the Sun’s most remarkable activity over the last five years.
The three minute video was released by Nasa on Wednesday to celebrate the fifth anniversary of their Solar Dynamics Observatory, and shows the changing surface of the Sun from June 2010 to February 2015.
Some of the highlights of the video include the dancing giant loops, hovering in the Sun’s corona, as well as solar flares being hurled into space from the planet’s surface in the form of light, energy and X-rays. The Sun can be seen changing colour, which according to Nasa is caused by different wavelengths of extreme ultraviolet light, ultraviolet light and visible light.
The video also captures some of the biggest sunspots that have been seen on the planet’s surface for almost 20 years.
To create the stunning video, the SDO team had to capture an image of the sun every eight hours during the five-year period, before putting them into the time-lapse.
Commenting on the video, a statement from the SDO said that they had created an “unprecedentedly clear picture” of how the Sun’s surface changes over time.
The agency said: “The imagery is captivating, allowing one to watch the constant ballet of solar material through the Sun's atmosphere, the corona.”
“By watching the sun in different wavelengths - and therefore different temperatures - scientists can watch how material courses through the corona.” The SDO was launched in February 2010, with the aim of helping scientists to understand the sun’s variability over time.
Since then it has continued to provide incredible images of the sun at nearly one every second.
The information taken from the images has also broadened the knowledge of scientists, with more than 2000 scientific papers being published on the back of SDO data.Reuse content
