SH2-101, commonly known as the Tulip Nebula, is a striking emission nebula located approximately 6,000 light-years away in the constellation Cygnus. This nebula is part of the Cygnus X region, a massive star-forming area in our galaxy, and owes its vibrant appearance to the ionization of hydrogen, sulfur, and oxygen gases by the powerful ultraviolet radiation from nearby massive stars.
In this image, the Hubble Space Telescope (HST) palette is employed to emphasize the different ionized elements present within the nebula. The HST palette assigns specific colors to different ionized gases: sulfur II (SII) is represented in red, hydrogen-alpha (Ha) in green, and oxygen III (OIII) in blue. This mapping allows us to visually dissect the chemical composition and structure of the nebula, revealing the intricate interplay of stellar winds, radiation, and gas dynamics within this stellar nursery.
Notably, SH2-101 is situated near the microquasar Cygnus X-1, a well-known X-ray source powered by a black hole in a binary system. The radiation and stellar winds from Cygnus X-1 likely influence the surrounding interstellar medium, contributing to the complex shapes and filaments observed in the nebula.

The application of the HST palette not only enhances the visual aesthetics but also serves as a valuable tool for understanding the physical processes at play within SH2-101. Each color in this palette represents different ionization states, providing insight into the temperature and composition of the nebula's various regions.
