Image Information

Quoted from SEDs:

NGC 6888, commonly known as the Crescent Nebula, is a Wolf-Rayet star expelling the outer layers of its atmosphere in phases. The central star has a strong stellar wind that is pushing away its envelope, indicating a supernova progenitor. The bubble is currently about 25 lightyears across and 5000 lightyears distant.
