What is a star that is just starting its life?

A star that is just starting its life is known as a protostar. This stage occurs when a region of a molecular cloud collapses under its own gravity, leading to the accumulation of gas and dust. As the material gathers, it heats up and forms a dense core, eventually igniting nuclear fusion in its core to become a main sequence star. Protostars are often surrounded by a rotating disk of material, which can lead to the formation of planets.
