A black hole is a collapsed star that is very small and a gravitational pull that is so strong that light cannot escape from it. No, they do not have outer colling layers. They just pull in anything that gets near it and crushes it to atoms. We can tell they exist by the effect they have on nearby objects.
You cannot see our sun.

because if they were on earth you wouldnt be asking this question
Black holes destroy planets or stars by exerting a powerful gravitational pull, which can rip them apart through a process known as spaghettification. Additionally, the intense tidal forces near a black hole can also strip away the outer layers of a star or planet, ultimately consuming them.
Black holes are formed when a massive star runs out of fuel and collapses under its own gravity. This collapse creates a singularity, a point of infinite density at the center of the black hole. The processes involved in their formation include the gravitational collapse of the star's core, followed by the expulsion of outer layers in a supernova explosion. The remaining core then collapses further to form a black hole.
This process is known as thermal stress weathering. It occurs when rocks expand and contract due to temperature changes, causing the outer layers to crack and break off. Over time, this repeated cycle of heating and cooling can lead to the disintegration and movement of rock layers.
When the outer layers of a star cool, it typically becomes a red giant or a supergiant, depending on its initial mass. As the star expands and its temperature decreases, it emits light primarily in the red spectrum. Eventually, it may shed its outer layers, leaving behind a hot core that can become a white dwarf, neutron star, or even a black hole, depending on the star's mass. The cooling process marks the later stages of stellar evolution, ultimately leading to the star's death.

Black holes actually come in different masses, and therefore sizes.
The core of a supernova can create dense neutron stars or black holes, while the outer layers can be expelled into space to form new stars, planets, and other celestial bodies. Additionally, elements with atomic numbers higher than iron are formed in a supernova's intense heat and pressure through nucleosynthesis.
Black holes are in outer space, far outside our solar system. Most galaxies have a large black hole at the center.
