| Notes | IC 5146, more familiarly known as the Cocoon Nebula, is located about 4,000 light years from earth in the direction of the constellation Cygnus the Swan. An open star cluster nursery is seen in the middle of this nebula with its brightest star being a massive youngster at about 100,000 years old. This bright star provides most of the energy responsible for the emitted and reflected light from this nebula. |
