Black holes are places in space where huge amounts of mass are packed into a tiny volume. This creates a gravitational pull so strong that even light cannot escape.

Black holes are created when stars collapse on themselves. When this happens, a supernova occurs. A supernova is a colossal explosion that happens when a star dies. A supernova’s power is equivalent to billions of nuclear bombs. Light is also emitted from supernovas which is over a trillion times brighter than the sun.

Supernovas do not always happen when a black hole is formed, a star can collapse and become a black hole without warning. Any black holes close to Earth are not dangerous because the closest one to Earth is around 1560 light years away, which is over 1500 years away. In the event that a black hole absorbs a star, the star will be ripped apart by the gravitational pull near the event horizon, the boundary surrounding the middle of the black hole. 

Parts Of A Black Hole:

Photon Sphere:

Photons are emitted from nearby jets or accretion discs. If there was no gravity, these photons would travel in a straight line. Due to the event horizon, the gravity is strong enough to warp the paths of the photons and create a light ring around the event horizon.

Singularity:

In the center of a black hole, matter has collapsed into infinite density called the singularity. All of the energy and matter that get pulled into a black hole end up there. The singularity causes an object’s density and mass to be infinite within an infinite small space.

Relativistic Jets:

When a black hole feeds on mass, the mass produces jets of particles and radiation that shoot out of each end of a black hole that can travel for light years in space. These particles are one of the most destructive particle accelerators in space and can destroy Earth if one was aimed and close enough to us.

Accretion Disc:

The accretion disc is a disc of superheated gas and dust whirls around a black hole at insanely fast speeds that produce electromagnetic radiation. This disc is what gives away a black hole’s location because the radiation emits light that can be found all over the electromagnetic spectrum. Some of the gas and dust can be sucked into the event horizon while some of it may be shot out to create jets.

How does a black hole die?

When a black hole loses its mass, it continuously shrinks and becomes hotter. When the black hole becomes so small and hot, it explodes into a huge burst of radiation and disappears.

Black holes are immense destructive masses in space that have a gravitational pull so strong that not even light can escape it.
