NASA releases stunning 10-year time-lapse of the Sun

NASA releases stunning 10-year time-lapse of the Sun”

Each second of the video represents one day in the sun's life, and the entire decade blazes by in about 60 minutes (though you can see our 6-minute highlight reel above).

And though NASA's SDO has watched the Sun without respite for 10 years, there are notable anomalies during the time-lapse. This video has been seen greater than 16 lakh occasions to this point. During that time, the SDO has captured high-resolution images every 0.75 seconds, resulting in 425 million images of the Sun.

Venus makes a swift fly-by at around the 12:20 mark in June 2012, while the Moon blocks off SDO's view briefly at around 53:30 in March a year ago. Published by NASA, the film is only 61 minutes, showing highlights of the slowdown in the 11-year cycle of the star.

Even though the SDO kept an "unblinking eye" on the Sun, some moments was missed.

A few dark frames are caused by the Moon or Earth briefly eclipsing the Sun.

The photographs used for the time-lapse video had been made by the Atmospheric Imaging Meeting - a multichannel imaging machine used for full-disc observations.

While an instrument failure resulted in a longer blackout in 2016. "The images where the Sun is off-center were observed when SDO was calibrating its instruments", NASA explained.

Firstly, the Atmospheric Imaging Assembly (AIA) is a battery of four telescopes created to photograph the Sun's surface and atmosphere.

Extreme Ultraviolet Variability Experiment (EVE), meanwhile, measures fluctuations in the Sun's ultraviolet output.

This is the frequent sunlight cycle, in which it moves from a period of time of substantial action referred to as the Photo voltaic Optimum to a time period of small activity referred to as the Solar Minimum amount.

NASA mentioned that the Solar Observatory monitored the Sun for 10 years. NASA hopes the mission will final for at the very least one other decade.
