M27
Dumbbell Nebula
The
M27 Dumbbell Nebula is a planetary nebula about 1360
light-years from us. It stetches about 1 1/2 light-years across. Like
all planetary nebulas, it is formed by emissions
from a white dwarf star in its center. Bright enough to be
seen through binoculars, the fainter outer wings that from the dumbbell
shape usually require a small to mid-sized telescope. North is at the
bottom.
