| Feb 3, 2019 at 3:03 | comment | added | Kimberly Bailey | Thanks! No, I was aware we cannot see any black holes, but they are almost always described in the way as in the picture, which is why I put quotes around 'see'. I was not trying to reference that we actually could see them! And yes, that is the question I was trying to figure out thank you very much!! | |
| Feb 2, 2019 at 4:40 | comment | added | Chappo Hasn't Forgotten | Perhaps your real question is about the shape of the accretion disk. In fact there's already exactly that question on our site - see Accretion disks - why are they disk-shaped, rather than spherical?. | |
| Feb 2, 2019 at 4:33 | comment | added | Chappo Hasn't Forgotten | Hi Kimberly, welcome to Astronomy. Your question "why do we see the black hole itself?" is impossible to answer, as it's based on an incorrect assumption. Can you give an example of where we "see" a black hole? I'm not aware of any. We detect black holes by inference: stellar orbits, intense radiation from an accretion disk, gravitational waves, etc. Artists' impressions are simply that: impressions, not real observation. Wikipedia is a good start for a better understanding. :-) | |

it was difficult to understand, so I rephrased it kinda but included the old one just in case)
