A nebula is a cloud which consists of gas or dirt/dust (e.g. cloud formed after a star explodes).
I massive star is much bigger than an average star.
Nebula-This is a nebula. When it collects enough mass, it begins to collapse under its own gravity.
Massive Star- When nuclear fusion begins, a star is born. If the cloud of dust is large enough then it will create a massive star.
Supernova's light up space with colors and essentially become even brighter than the other nearby stars.
Red/Orange Super giant-So much energy is released that the star swells into a super giantThe core gets so hot that the helium can fuse into heavier elements (e.g. carbon and silicon)
When silicon in the core is eventually transformed into iron thenonce the core becomes iron, no further fusion can occur.
Supernova-So the core would collapse without anything to burn, which results into a huge explosive called a supernova.
Black hole-If the remaining core is 3 solar masses or greater, the collapse of the star cannot be stopped.The neutron star continues to shrink until it finally becomes a black hole.
Black holes suck everything in due to having a tremendous gravitational pull.
