1. What is a Wolf–Rayet nebula?A Wolf–Rayet nebula is a glowing shell of gas and dust that is ejected by a very massive star called a Wolf–Rayet star. It looks like a colorful bubble in space.
2. How do Wolf–Rayet stars create nebulae?The star blows out its outer layers with powerful winds that move thousands of kilometers per second. The wind pushes the gas and dust into space, forming a bright shell around the star.

Wolf-Rayet Star: A rare, massive, luminous star undergoing rapid mass loss due to intense stellar winds in its late evolutionary phases.
Stellar Winds: Outflows of ionized gas and particles from a star, driven by extreme radiation pressure and high temperatures in Wolf-Rayet stars.
Galactic Chemical Evolution: The process by which the abundance of chemical elements in a galaxy changes over time through stellar nucleosynthesis and mass ejection.
