- A nebula is a huge cloud of combined gas and dust in space12. Nebulae are made up of gas, primarily hydrogen and helium, and fine cosmic dust1. They can contain hydrogen, helium, and/or plasma2. Nebulae are part of the interstellar medium of extremely low-density gas and dust that exists between stars in the void of space1. There are different types of nebulae, including planetary nebulae, emission nebulae, and diffuse clouds of gas345.Learn more:✕This summary was generated using AI based on multiple online sources.

These clouds are part of the interstellar medium of extremely low-density gas and dust that exists between stars in the void of space, material so dispersed through the vastness of the cosmos that it can have a density as low as 0.1 atoms per cubic centimeter.science.nasa.gov/mission/hubble/science/universe …A nebula is a huge cloud of combined gas and dust in space. It can contain hydrogen, helium, and/or plasma. They are sometimes considered nurseries, because oftentimes they are the location where stars are created and born.nineplanets.org/questions/what-is-a-nebula/Planetary nebulae are shells of gas cast off by dying sunlike stars, and they are usually rich in hydrogen and oxygen. With the central star energizing the gas, these nebulae tend to appear bright in light emitted by both elements.www.scientificamerican.com/article/a-recently-disc…Emission nebulae are diffuse clouds of gas that have become so charged by the energy of nearby massive stars that they glow with their own light. The radiation from these massive stars strips electrons from the nebula’s hydrogen atoms in a process called ionization.science.nasa.gov/missions/hubble/hubble-surveys …An emission nebula is a nebula formed of ionized gases that emit light of various wavelengths. The most common source of ionization is high-energy ultraviolet photons emitted from a nearby hot star.en.wikipedia.org/wiki/Emission_nebula
