Answer :
Explanation:Low-mass stars turn into planetary nebulaetowards the end of their red giant phase. As these stars become highly unstable, they start to pulsate, producing strong stellar winds that throw off their outer layers. The outer layers drift away, leaving behind a small, hot, bright core called a white dwarf. This white dwarf emits ultraviolet radiation, which illuminates the surrounding layers of gas, creating the planetary nebula. Despite the name, planetary nebulae have nothing to do with planets; they got this name because early astronomers using small telescopes thought they looked somewhat like planets. Over time, the material from the planetary nebula is scattered into space and eventually contributes to the formation of new stars in clouds of dust and gas¹.
In contrast, high-mass stars undergo a more dramatic fate. When they exhaust their nuclear fuel, their cores collapse under intense gravity, leading to a **supernova explosion**. This explosion releases an enormous amount of energy, creating heavy elements and dispersing them into space. Supernovae play a crucial role in enriching the interstellar medium with elements necessary for forming new stars and planets². So, while both low-mass and high-mass stars have fascinating life cycles, their outcomes differ significantly due to their initial masses and internal processes.
