Nebulae are giant clouds of dust and gas in space. They serve two primary roles in the universe's lifecycle:
Dense regions within a nebula can collapse under gravity to form new stars; these are often called "stellar nurseries".
Planets are formed from the leftover debris of star formation. Planets Reported to Shape Planetary Nebulae PLANETS STARS NEBULAS
Some nebulae are formed from the gas and dust ejected by dying stars, such as Supernova Remnants . 2. Stars: The Engines of the Universe
Stars are massive spheres of plasma held together by gravity, primarily fueled by . Their evolution depends entirely on their mass: Nebulae are giant clouds of dust and gas in space
Stars like our Sun eventually expand into red giants before shedding their outer layers to form a Planetary Nebula .
These stars end their lives in violent supernova explosions, enriching the surrounding space with heavy elements that eventually form new nebulae and planets. 3. Planets: The Building Blocks of Systems Planets Reported to Shape Planetary Nebulae Some nebulae
