The Dream Nebula is an emission nebula in Eqien's Galaxy. It was created after a small burst of star formation produced the massive star Birling, which ionised the surrounding area. Star formation is still going on, but Birling is in the final stages of its life.
Structure[edit | edit source]
The Dream Nebula is mainly composed of a large shell surrounded by knots of hot gas, ejected by Birling's fierce solar wind. Purplish filaments are also present in the nebula, and are sites of vigorous star formation. Several Bok Globules have been spotted, such as the Olstan cloud.
Stars[edit | edit source]
The Dream Nebula currently has several stars in it, but some are not actually part of the nebula and just happen to be there.
- Birling: The most important star in the nebula, Birling is a hot WC4 class Wolf-Rayet star nearing the end of its life. It has just 15,000 years until it blows in a Gamma-Ray Burst. Birling is so bright that it continuously ionises the nebula, keeping it bright. A black hole will be the remnant of the death of this star, and the supernova that results from its death will cause even more star formation, prolonging the nebula's life.
- Entyraph: A Be star, Entyraph spins rapidly, completing a rotation every 8 hours. It is arguably the second most important star after Birling, as it also helps ionise the nebula, but that will change soon. When Birling dies, more new stars will be created.
- Ira: Ira is a white dwarf with a cyan accretion disk. It just happens to be there, and has 3 planets, one of which has life (Eurya).
- Nuskuris: A binary between the two young red dwarfs Nuskue and Elerad, Nuskuris is just one of many young systems in the nebula. 3 planets have been detected in the system.
- Olsto: Olsto is a young Ae star surrounded by a Bok Globule. It has no planets.
- Daharrus: A rogue planet, Daharrus may not seem so interesting at first. Though upon closer inspection, its youngness still allows substantial oceans of water to flow, complete with bioluminescent bacteria!
