Planetary Nebula


Constellation: Cepheus
Bow Tie Nebula
This planetary nebula was discovered by WF Herschel in 1786.  The star is shedding its layers something like what will happen to our sun here in several billion years.  Astronomers think that in about 30,000 years the Bow Tie will just be a white dwarf.
