| Object type: | Planetary nebula | |
| Size: | 2.0' | |
| Magnitude: | 16 mag | |
| Constellation: | Cyg | |
| Distance: | 5,000 Ly | |
| Notes: | Abell 78 is a planetary nebula in constellation Cygnus. It has the unusual property of having a faint outer halo composed of normal stellar material (mostly hydrogen) and a bright inner elliptical ring composed mostly of helium. The helium ring provides direct confirmation that hydrogen is being converted to helium in the centers of stars and can later be ejected back into the galaxy's pool of gas for building another generation of enriched stars. | |
