You can find videos of an active black hole:

You cannot “see” the black hole directly, but you can see the stars orbiting the black hole and the effect of gravitational lensing.
In a similar way when you see your own hands, are aren’t really seeing your hands, but the photons bouncing off your hands into your retina.
Such a cool video! Apparently it's a time lapse taken over 20 years.
It takes our solar system 225 MILLION years to orbit the black hole in the centre of the milky way galaxy.
