A black hole can be defined just like why an object looks black. Yes because it absorbs all lights and doesn’t allow any light to reflect back so it looks black. Likewise black hole is any region in space which doesn’t allow light to escape.
The picture is taken accurately with black hole in front of Large Magellanic cloud. Large Magellanic Cloud is a galaxy which is irregular in shape. It can also be written as LMC. One more interesting fact about LMC is that it is the third closest galaxy to milky way with a mass of ten billion times of our sun.
Around it small small rings can be seen. These are Einstein Ring that is produced due to the affect of gravitational lensing. Whenever light coming from a bright source bends around a massive object, gravitational lensing occurs.
This beautiful image is just a small sample of God’s creation. There are much more to be seen.
