SupergiantA massive star in a late stage of life, tens of thousands to hundreds of thousands of times as luminous as the Sun, of luminosity class I. Red supergiants such as Betelgeuse are among the largest stars known; blue ones such as Rigel are among the brightest. Most end as supernovae within a few million years of forming.

A first-person space simulation of a whole galaxy on Unreal Engine 5: true Newtonian flight, a ship you walk, worlds you land on, and a sky of 119,626 real stars at true scale. Pre-alpha, and playable.
