Nebulae glow because they are made up of gas and dust particles that are illuminated by nearby stars. These particles scatter and reflect starlight, creating the glowing appearance. Additionally, some nebulae may also emit light due to processes such as ionization or radiation.
The main types of nebulae are emission nebulae, reflection nebulae, dark nebulae, and planetary nebulae. Emission nebulae glow with their own light, often due to hydrogen gas being ionized by nearby stars. Reflection nebulae reflect light from nearby stars. Dark nebulae are dense clouds of dust that obscure light. Planetary nebulae are the ejected outer layers of dying stars.
Emission nebulae glow due to the ionization of their gases by energetic radiation from nearby hot stars. These stars release ultraviolet light that strips electrons from atoms in the nebula, causing the atoms to recombine and emit light at specific wavelengths, creating the colorful glow seen in these nebulae.
The most common gas in nebulae is hydrogen. Hydrogen makes up about 90% of the atoms in the universe and is the building block for stars and galaxies. It emits light in the red part of the spectrum, creating the characteristic pink or red glow of many nebulae.
There are several types of nebulae found in outer space, including emission nebulae, reflection nebulae, dark nebulae, and planetary nebulae. Emission nebulae are clouds of ionized gas that emit light, reflection nebulae reflect light from nearby stars, dark nebulae are dense clouds that block light, and planetary nebulae are the remnants of dying stars.

emission nebulae and reflection nebulae.
Nebulae are named based on their appearance, location in the sky, or the discoverer. Common types of nebulae include emission nebulae, reflection nebulae, and planetary nebulae. They are often given informal names that describe their shape or features.
The different types of nebulae include emission nebulae, reflection nebulae, and dark nebulae. Emission nebulae are clouds of gas and dust that emit light, reflection nebulae reflect light from nearby stars, and dark nebulae are dense clouds of dust that block the light from behind them.
Planetary nebulae have temperatures that can range from about 10,000 to 30,000 degrees Celsius. This high temperature is due to the intense ultraviolet radiation emitted by the central white dwarf star that ionizes and heats up the surrounding gas and dust, causing it to glow brightly.

The two main types of bright nebulae are emission nebulae, which emit light from ionized gases, and reflection nebulae, which reflect light from nearby stars. Emission nebulae are usually red or pink in color, while reflection nebulae appear blue due to scattering of light.
