Something Wonderful: What We Can See By Looking At the Sun

Three Years of SDO Data narrated by NASA's Goddard Space Flight Center heliophysicist Alex Young.

SDO’s Atmospheric Imaging Assembly captures a shot of the sun every 12 seconds in 10 different wavelengths. The images shown here are based on a wavelength of 171 angstroms, which is in the extreme ultraviolet range and shows solar material at around 600,000 kelvins (about 1.08 million F). In this wavelength it is easy to see the sun’s 25-day rotation as well as how solar activity has increased over three years. NASA - Three Years of SDO Images

This image is a composite of 25 separate images spanning the period of April 16, 2012, to April 15, 2013. It uses the SDO AIA wavelength of 171 angstroms and reveals the zones on the sun where active regions are most common during this part of the solar cycle.

Amazing image

Amazing video. Even more amazing is that all that solar activity apparently has absolutely nothing to do with "climate change" here on earth. /sarc

I found it profoundly disconcerting.

The Sun. Such a happy thing; I'm so happy to see it and feel it's warmth.

It's a roiling inferno exquisitely balanced between explosion and implosion. Cthonic, Implacable and violent. How could there be a place under it's glare for me?

Here, but for the Grace of God, go I.

Unfortunately, I only read the title of your post "What We Can See by Looking At The Sun" and decided to follow your advice. Now I'm blind. Thanks a lot. My Lawyers will be contacting your lawyers.
