Visibility III / V
About 6,000 light-years away is this emission mist, nicknamed Tulip Mist.
The subject is quite beautiful, very red and in many pictures resembles a nickname.
However, I was actually more interested in a ‘nearby’ object that can be said to belong to the history of astronomy.
Namely, in the 1960s, a powerful X-ray source was discovered in the area, and subsequent studies have found the object most likely to be a black hole - called Cygnus X-1 .
(This subject was once so inspiring that the Canadian progressive rock band Rush made it a song).
Around the black hole is believed to be an accumulation disc and showers coming from the poles.
One of these jets collides with interstellar matter and an arc forms on the shock wavefront, which is faintly visible in the image.
