Emission nebula - Wikipedia
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.

Emission nebula, in astronomy, a bright, diffuse light sometimes associated with stars whose temperatures exceed 20,000 K. The excitation process necessary to provide observed optical and radio energies in such gaseous regions was long an astronomical puzzle.

A famous example of an emission nebula is the Orion Nebula, a huge, star-forming nebula in the constellation Orion. The Orion Nebula is home to a star cluster defined by four massive stars known as the Trapezium.

Emission nebulae are clouds of ionised gas that, as the name suggests, emit their own light at optical wavelengths. Their mass generally ranges from 100 to 10,000 solar masses and this material can be spread over a volume of less than light year to several hundred light years.
Emission Nebula Facts - The Planets
An emission nebula is a cloud of ionised gas, due to high energy photons emitted from a nearby star with the nebula. Reflection nebula are clouds of dust which are simply reflecting the light of a nearby star or stars.

Oct 9, 2023 · What is an Emission Nebula? An Emission Nebula is a type of astronomical object made up of ionized gases that emit light of various colors. Essentially, it’s a big cloud of gas and dust in space...
RIT professor leads research showing true structure of the iconic …
4 days ago · The CO emission reveals cold, molecular gas that envelopes the hot gas and dust seen in images of the nebula obtained by the Hubble Space Telescope (HST) and, more recently, the James Webb Space Telescope (JWST). "We looked at the data and the ellipsoidal structure was obvious, so we could put together a simple geometrical model.

The magnificent emission region, the Orion Nebula (aka M42), lies at the upper right of the picture. Immediately to its left are a cluster of of prominent bluish reflection nebulae sometimes called the Running Man. The Horsehead nebula appears as a dark cloud, a small silhouette notched against the long red glow at the lower left.
