Today’s image features the Headphone Nebula, also known as PK 164 +31.1 or Jones-Emberson 1 . This planetary nebula , the remnant of a dying Sun-like star, faintly occupies an angular region of the Lynx constellation about 1/5 th the diameter of the full moon. The red and blue-ish green colors trace hydrogen and oxygen atoms, respectively, that have been excited and ionized by the nebula's central white dwarf . The headphone shape, where two lobes of hydrogen puncture the inner region of oxygen, adds this object to a long list of oddly shaped nebulae . The morphology of such strange nebulae hint at the presence of a stellar or planetary companion , which can stir the material flowing out from the dying star. You can listen to Hubble and JWST sonifications of planetary nebulae through your very own headphones!\n\n#APOD #Astrogeek #Astroeducation #Universe #Astronomy\n\nhttps://apod.nasa.gov/apod/ap260527.html\n",
