Vernarca Nebula

The Vernarca Nebula is a large and young nebula located in the outer ring of the Silky Way that gave birth to the well known stars Gagibah, a blue hypergiant, Starrial, a white main sequence star and one of the capitals of the Verdan Federation, and the yellow giant Bakino. 
== Physical Characteristics ==
The Vernarca Nebula is plainly visible in the night sky of most planets in the Ervo Sector, taking up much of the Terallan sky. It contains approximately 200,000 stars in it, and is among the densest regions in the Silky Way's galactic ring. It has many large clusters of stars and an extreme overabundance of massive stars, which causes the nebula to glow due to the ionization of its dense gases. 
== Coloration ==
The Vernarca Nebula has a distinctive blue color, because of the sheer amount of light emitted by the largest stars. However, in places, it has a strange green tint. After much careful observation and lab research, Federation astronomers found that this phenomenon is manifested by a low-probability electron transition in doubly ionized oxygen. This is nearly impossible to reproduce in the lab, because it depends on the quiescent and nearly collision free environment in deep space. Of course you can build a lab in deep space, negating this problem.
== Stellar Wind and Effects ==
Once formed, the stars within the nebula emit a stream of charged particles known as a stellar wind. Massive stars and young stars have stronger stellar winds than the Sun or Verda. This wind forms shock waves when it encounters gas in the nebula, and this in turn shapes the gas of the nebula, forming it into pretty shapes and triggering collapse in some areas, forming sterrs.
There are four different kinds of shocks in the Kerillis Nebula. Many are features in Herbig-Haro Objects.
* Bow shocks are stationary and are formed when two particle streams collide with each other. They are present near the hottest stars in the nebula where the stellar wind speed is estimated to be thousands of kilometers per second and in the outer parts of the nebula where the speeds are tens of kilometers per second. Bow shocks can also form at the front end of stellar jets when the jet hits interstellar particles.
* Jet-driven shocks are formed from jets of material sprouting off newborn T-Tauri stars, like Klein. These narrow streams are traveling at hundreds of kilometers per second, and become shocks when they encounter relatively stationary gases.
* Warped shocks appear bow-like to an observer. They are produced when a jet-driven shock encounters gas moving in a cross-current.
* The interaction of the stellar wind with the surrounding cloud also forms "waves" which are believed to be due to the Hydrodynamical Kelvin-Helmholtz Instability.
== List of Stars ==
The Vernarca Nebula is ionized by a number of clusters, including the Hadauk Cluster surrounding Hadeos and Gagibah, the Parallelogram Cluster near Inielus and Bakino, and a collection of others. 
=== Hadauk Cluster ===
* Hadeos (ABC), a triple star system composed of two O-type stars in a close binary, with a distant B type star
* Gagibah (VeNSO 3), a relatively old blue supergiant
* Rigela, a fairly large newborn main sequence star, parent star of New Tarash
* Athos, a pulsar at the center of a supernova remnant which destroyed the Tyran Empire
* Anhooie, a young F-type main sequence star which was once the capital of the Tyran Empire before the Athos Supernova
* Hadra, a wolf-rayet star that is currently being carefully starlifted to prevent another, even stronger supernova from ravaging the region
* Varaltin-Zartha, a low-mass binary system and a point of contention between the Tyran Free State and Falacian Dominion. 
* Vernarca System (MWRSSC 3/VeNSO 1 and 2), a cataclysmic binary between two wolf-rayet stars, one of the most extreme systems in the area
* Quantum, a binary system of two yellow dwarfs at the far edge of the cluster
=== Parallelogram Cluster ===
* Bakino (VeNSOOP 3/CASPS 2), a yellow hypergiant with a very very very far out planet
* Yakto (PBDC 8/VeNBD 1/VeLSDOS 400), a large forming brown dwarf
* Inielus, a LBV near the center of the cluster
* Thalos, a cataclysmic binary of a red giant and neutron star
* Olorat/Oltoris, a distant binary of a red supergiant and blue giant
* Kerillis, a 50-solar mass O-type main-sequence star that is being carefully starlifted by Marakat
* Veltoris, a lone yellow supergiant star close to Kerillis
* Smizok, a yellow hypergiant near the Tyran Free State border
* Raga, a pulsing protostar system
* Enolia, an orange dwarf that was once home to the Enolian species at Canamar
* Fanior, a system with 6 stars
* Deferna, a 3 star system with one B-type star and two A-types in a binary
* Bioner (VeLSDOS 868/VeNBD 2/VeNBDOP 1), the star with the lowest mass of any non-brown dwarf star in the entire Silky Way
