A typical diffuse nebula is a few hundred light-years across. See also the Horsehead Nebula Planetary Nebulae.

So far they have only been found in the high-redshift universe because of the ultraviolet nature of the Lyman-alpha emission line.
Nebulae. H-alpha light is the brightest hydrogen line in the visible spectral range. Planetary nebulae are shells of gas thrown out by some stars near the end of their lives. It is important to astronomers as it is emitted by many emission nebulae and can be used to observe features in.
Mar 18 2020 Dark nebulae are also often seen in conjunction with reflection and emission nebulae. These are the brightest and most interesting nebulae listed in the Herschell 400 Catalog. In astronomy a Lyman-alpha blob LAB is a huge concentration of a gas emitting the Lyman-alpha emission lineLABs are some of the largest known individual objects in the UniverseSome of these gaseous structures are more than 400000 light years across.
Our Sun will probably produce a planetary. It occurs when a hydrogen electron falls from its third to second lowest energy level. Herschel nebulae are generally fainter and harder to spot than Messier and Caldwell nebulae.
The famous Horsehead Nebula Barnard 33 is also located close to the Flame Nebula. H-alpha Hα is a specific deep-red visible spectral line in the Balmer series with a wavelength of 65628 nm in air.
