You know how, as a kid, you were always warned not to look directly at the sun? Thanks to videos like this, you don’t have to.
The entire video, on the NASA website, covers 24 hours of solar activity back on September 25, 2011, in about 2 minutes, 45 seconds.
The colors appear blue and gold because additional processing was added to enhance the details.
There’s no scientific value to the processing, it just looks cool!
