Description

The Tulip Nebula is an emission nebula located in the constellation of Cygnus.  Just to the right of the bottom of the nebula (as oriented in this image) is the first discovered black hole, Cygnus X-1.  Jets of energised particles are emitted from the black hole's accretion disk.  Where these energised particles interact with a relatively dense part of the interstellar medium a "bow wave" is created - seen as a blue arc in the image.  In a recent study published February 2021 the mass of Cygnus X-1 has been estimated at around 21 times that of our sun and it is estimated to be around 7,200 light years from Earth.
