What the heck is going on on the sun?

[Katana1000S]

I don't know what the dark shadow is? does it say on the NASA site or do they mention if there is any concern about it?

Stunning images though.

I think the sort of time scale we are used to as Humans we'll not see much real change in the sun deteriorating during our whole existence as a species ... probably* obviously we will see periods of sunspots and solar flare activity from time to time, used to do some welding at an oil yard and someone said have a look at the sun through your welding visor, I had one of the darker shades of glass in use at the time and we could quite clearly see the sun spots that were active at the time ... this was a good way to observe the UK eclipse of 1999 as I recall too.

One sun that is due to go pop soon (ish) and maybe in our lifetimes is Betelgeuse, that would be amazing to see.

Interesting stuff.
