This is Dolly Blu before she became a Massive Star. Every star starts off as a Stellar Nebula and a protostar. Next, they transform into an Average star or like Dolly a Massive star.
The star is a representation of what it started and how it grew through out its life
Meanwhile, she transforms and becomes a Massive Star. This is the outcome after the transformation as she started off as cloud and dust.
This is Dolly Blu as a massive star after being a Stellar Nebula and protostar
After being a Massive star which is a star that is made up of helium and hydrogen for some time. Later, Dolly then becomes a Red Supergiant when she started running out of hydrogen fuel and began collapsing.
This is what Dolly Blu looks like as a Red Supergiant
Eventually, Red Supergiants then transform into a supernova which is an explosion using remaining fuel of the past star
This is the explosion that is caused by all the fuel
Prior to being a supernova, a Neutron Star is created when a big star dies and their core collapses in the supernova where protons and electrons meet.
The cycle must continue and it can't stay a supernova forever until finally, it forms the neutron star
Concluding the cycle, the Neutron Star becomes a black hole if it is more than three solar masses. There it will reach zero-dimensional point when it comes to the gravitational point
The black hole sucks everything in leaving then trapped and powerless
