Check out the inner and outer structures. Which filters are best at showing the inner and outer layers of the star's gas "tube?"
Notice the white dot in the middle?
This is probably going to be the Sun's fate. When it starts to run out
of fuel it will "burp out" a "bubble" of very hot gas. The rest of the
star will collapse and form a white dwarf. At this time the earth will
either be vaporized or fried. In any case, I don't think spf15 will be
of any help. You don't have to worry. It won't happen for a little while.
(5 billion years from this past Sunday, I think.)
