Catalog of Cygnus planetary nebulae
Scope out this constellation's dozens of dying stars.
May 26, 2009
Many more planetary nebulae await you in Cygnus the Swan. Download this table for detailed information about 53 planetaries, including where to find them and how they are classed. Bold entries are described in my article in the July issue of Astronomy, "Explore planetary nebulae in Cygnus."
One of the more bizarre planetaries, NGC 7008 reminds many of a human fetus. The bright spots on the northern tip and at the western edge are regions of dense gas — not stars.
