Description

This is a narrow band image, in modified SHO ("Hubble") palette, of the so-called Tulip nebulae, Sharpless 2-101. But I'd also highlight the two shock bows that are seen in this field, one of them in fact is an evidence of a black hole, the first one ever confirmed. More details in the link above.
