Other designations
Endurance Dwarf, CelWP G-G1

The Endurance Galaxy, also known as CelWP G-G1, is an dwarf spiral galaxy in intense star formation, with the highest rates of stellar birth in any galaxy of the universe. Its also covered in many H II regions that span the entire galaxy. Its origin is rooted on Rongya, a heavy-wind blue straggler which is also the brightest star in the galaxy. The rapid formation of Endurance is considered the most extreme example of the domino effect in history.

Notable objects

Stars

- Rongya, the birth star that marked the origin of this galaxy.

- Nerise, the nearest star system to Rongya, with its own planetary system.

- Vision of Endurance, the central black hole, weighting at 436 solar masses.

Nebulae

- EH2RC-1 to -5, some of the largest H II regions in Endurance.

- Rongya Nebula, a large wind nebula surrounding the blue straggler.

- Southwest Endurance Nebula, which contains an star cluster.

- Great Red Nova, heavily studied supernova remnant which is notable for its distinct red shape.

Dwarf satellites

Endurance also has an unique feature among satellite galaxies: it has its own dwarf satellite galaxies as well. Five of then are known so far, with most of then being dwarf spheroidals. They are named Endeavour, Enterprise, Envisage, Encourage, and Envision.
