Yeah, the coolest thing about the sun, imo, is that while a particle of light only takes a few minutes to reach earth, it can take millions of years to escape the tumultuous interior of the sun to radiate in the first place. That activity is what prevents the sun from collapsing under its own gravity.

We can’t change our earthly perspective, no, but we do have numerous satellites that do have the ability to see certain angles we can’t currently on earth. We can’t see the backside of it (from our current perspective, it rotates and we orbit so we do see all of it), really, because we’d never get good signal from our craft, but we can get some decent side angles.

We just don’t necessarily have the tools to see what we want to know with those specifically, but we put out great new tools on a regular basis, so it’s very possible they will make new tools just for that purpose.

As for the other question about not being able to detect it - not really. The stuff we have focused on the sun mostly works with hot material, but the universe itself is very cold, and we can detect things from every wavelength we are aware of, it’s just a matter of what’s usually focused on the sun specifically to catch these things.

(Disclaimer for anyone who might read this: do not ever look at the sun through a telescope without a certified solar filter, you will burn out your eye. Guaranteed.) If you have a telescope, on a sunny day you can watch the sun indirectly by facing the eyepiece toward paper or a wall. It works like a projector. It’s black and white just because it’s bright out when you project it, but you can watch sunspots and stuff. :) and now is a great time to do it a we are approaching the solar maximum, when the most interesting things tend to happen.
