The Crescent Nebula
Like the Bubble Nebula, and Thor’s Helmet, this is formed by the fast stellar wind of the extremely hot star at its heart – which interacts in complex ways from the wind left over from when this star was a red giant. This is roughly 5,000 light-years away.
These images were taken over the span of a couple of years, and feature various combinations of true-color and narrowband data.
