Nasa released a mesmerizing time-lapse video of the Sun capturing the activity on the solar surface over the last decade.
The 61-minute video has been produced from 425 million high-resolution imagery captured by the Solar Dynamics Observatory (SDO) spacecraft in the Earth's orbit. Each second on the video, from June 2, 2010, to June 1, 2020, represents a day at the centre of the Solar System.
The SDO spacecraft is able to safely view the sun and pay witness to its moods, outbursts and stretches of relative calm - bright flashes are eruptions, while dark patches are sunspots.

According to CNET, the video goes dark when the Earth or moon get in the way of SDO's view while there was also a technical glitch in 2016 that created a brief camera blackout. There are scenic outbursts and eclipse action as a bite of black moving across the sun's disc.
"From its orbit in space around Earth, SDO has gathered 425 million high-resolution images of the Sun, amassing 20 million gigabytes of data over the past 10 years," NASA said in a statement.
While according to a report in Business Insider, NASA's time-lapse video makes the sun look like a rotating disco ball: brilliant in places, shadowy in others. This is because the sun's hot gases are constantly moving, creating sunspots: darker, cooler patches on the sun's surface that form when magnetic fields are particularly strong.
In October 2014, the largest sunspot in nearly a quarter-century was observed and appeared as a patch about the size of Jupiter. The sunspot set off multiple explosions known as solar flares, which appear as bright flashes in the video.
In 2014 the sun's magnetic energy reached a peak, known as a solar maximum, and explosions and flares on the sun's surface were so violent, they could be seen as light from the Earth's surface. Solar maxima can also trigger power outages and electricity shortages.
