Because they expand, due to modecules in the air, most red gaints start out as tiny stars known as "white dwarfs" which, over millions of years, expand to form a red giant. Eventually after billions of years the Red Giant collapses and turns into a supernova, which can then form into a Black hole

ReneStars become super red giants when they exhaust their core hydrogen fuel and start burning heavier elements. This causes the outer layers of the star to expand and cool, giving them a red appearance. Eventually, the star will undergo a series of nuclear reactions that lead to its expansion before it eventually collapses or explodes.

What is are some names of super giant stars?
Some names of supergiant stars include Betelgeuse, Antares, Canopus, and Rigel. These stars are among the largest and most luminous in the universe.
What happens to a star when it becomes a super giant?
Some do, some become "bright giants" instead.
What happens to very massive stars when they die?
Very massive stars can undergo a supernova explosion when they die. This explosion can leave behind a dense core known as a neutron star or in extreme cases, a black hole. The explosion also disperses heavy elements created in the star's core into space, enriching the interstellar medium for future star formation.
Do protostars always become stars?
Not all protostars become true stars. Some protostars may not have enough mass to sustain nuclear fusion in their cores and never become true stars, instead becoming failed stars known as brown dwarfs.
How do some stars become shooting stars?
Shooting stars are not stars. They are bits of dirt and dust that burn up in our atmosphere, briefly making them look like stars. Most of that is debris is from comets or others bits of dirt in space, but they are not stars and were not stars. So stars do not become shooting stars.
