Protostar: a cloud of gas and dust collapses under gravity and becomes a hot, dense protostar.
Main sequence: the star burns hydrogen and generates heat and light.
Red giant: the star runs out of hydrogen and expands, becoming cooler and redder.
Planetary nebula: the outer layers of the star are expelled into space, creating a beautiful glowing cloud known as a planetary nebula.
White dwarf: the core of the star remains as a small, hot white dwarf that slowly cools down over billions of years.
☀️ For a massive star, after the main sequence stage ...
Red supergiant: the star runs out of fuel and expands rapidly, becoming a red supergiant.
Supernova: The explosive stage when the core of the red supergiant collapses, causing a massive explosion.
Neutron star or black hole: the core of the star becomes either a neutron star or a black hole, depending on its mass. A neutron star is a dense object that spins rapidly. A black hole is an object with such strong gravity that nothing can escape it.
Suppose you have a cup of hot coffee and a bowl of ice cream. If you leave them both on a table for some time, the coffee will cool down, and the ice cream will melt, until they reach the same temperature. This happens because the coffee and the ice cream are in contact with the surrounding air, which is at room temperature. Therefore, they transfer heat to the air until they reach thermal equilibrium with it. Once they reach thermal equilibrium, they will be at the same temperature as the air, and they will no longer transfer heat to or from it.

Life cycle of a star like our sun 🌞 :
Protostar: a cloud of gas and dust collapses under gravity and becomes a hot, dense protostar.
Main sequence: the star burns hydrogen and generates heat and light.
Red giant: the star runs out of hydrogen and expands, becoming cooler and redder.
Planetary nebula: the outer layers of the star are expelled into space, creating a beautiful glowing cloud known as a planetary nebula.
White dwarf: the core of the star remains as a small, hot white dwarf that slowly cools down over billions of years.
