Planetary Nebula, Misnamed but not Misunderstood

Chandra issued an image release on 12/02/21, "Planetary Nebula, Misnamed But Not Misunderstood.”  A new collection of planetary nebulas, containing X-rays from Chandra and optical light from Hubble, is available.  A planetary nebula is a phase that stars like our Sun experience after they use up much of their fuel.  “Planetary nebula” is a misnomer stemming from the 19th century and their resemblance to planets as seen through small telescopes. The planetary nebulas in this collection range in distance from about 2,200 to 5,900 light years from Earth.
