APOD: Solar Granules at Record High Resolution (2020 Feb 03)

Explanation: Why does the Sun's surface keep changing? The help find out, the US National Science Foundation (NSF) has built the Daniel K. Inouye Solar Telescope in Hawaii, USA. The Inouye telescope has a larger mirror that enables the capturing of images of higher resolution, at a faster rate, and in more colors than ever <a rhef="ap110918.html">before</a>. Featured are recently-released first-light images taken over 10 minutes and combined into a 5-second time-lapse video. The video captures an area on the Sun roughly the size of our Earth, features granules roughly the size of a country, and resolves features as small as 30-kilometers across. Granule centers are bright due to the upwelling hot solar plasma, while granule edges are dim due to the cooled plasma falling back. Some regions between granules edges are very bright as they are curious magnetic windows into a deep and hotter solar interior. How the Sun's magnetic field keeps changing, channeling energy, and affecting the distant Earth, among many other topics, will be studied for years to come using data from the new Inouye telescope.

Know the quiet place within your heart and touch the rainbow of possibility; be
alive to the gentle breeze of communication, and please stop being such a jerk.

I find it mind opening to have a "close up" video of so much matter moving so quickly.

Also a visual of the power of magnetism.

Of course, this is a lot of matter moving quickly (although it's still close to a vacuum, with a density only about 1/4000 that of our atmosphere at sea level). But keep in mind we're seeing it sped up 120 times.

Thanks. I didn't account for the density. I kind of thought it was like molten metal.
