>>5506021A simulation of a black hole passing in front of a galaxy that's millions of light years away, in order to show how black holes warp light around them since, their gravity is so strong, that they make photons themselves orbit around them.
We have no pictures of black holes, mainly because you can't see them, only the effects they cause light warping light behind them, or their accretion disks if they are absorbing stuff.
If a black hole is not absorbing anything, and there's no noteworthy light behind it, you could fly into one without even knowing it.
The closest thing to a picture of a black hole we have is pic related, Sagittarius A, the black hole that holds our entire galaxy together.
