Thank you. If I was in a spaceship at a much closer distance to the object than I am right now, would I be able to see the dust and the shape similar to what we see on the photos? Or is this all invisible to the human eye?
Sure. It's a physical object, reflecting broadband light from nearby stars. The colors would be different, and you might not see the same fine structure without filters, like how the Sun looks very different through a Calcium K line filter https://thelonelyphoton.com/2022/01/08/solar-imaging/
Given its size the density is probably pretty low, though. If you got right up next to it you wouldn't see much, in the same way a fog bank gets less visible when you walk towards it.
Thank you - your explanation and that photo of the Sun with the Calcium K filter are very helpful.
With so many colorized photos of space objects and so many artist impressions, I wasn’t sure whether space is just a black void to the human eye or we are capable of seeing the gorgeous colors of different nebulae and such.
Take the colorized image to B&W, and that would be closer to what the human eye could see.
If you've ever been to a dark sky location so that you could see the Milky Way, then that's about what you'd see. Our eyes just are not sensitive enough to pick out colors. Even in a telescope, viewing objects like Orion's Nebula, which is incredibly bright, it is just B&W in the eye piece. Viewing Andromeda galaxy is also just B&W.
About what you'd see from a 16 inch telescope in a superb dark sky location. A red smudge with hints of finer detail.
