Planetary Nebula in the constellation Lynx.
PK164+31.1, also known as Jones-Emberson 1, is a low bright planetary nebula that lies about 1,600 light years away towards the constellation Lynx. Due to its magnitude 17 it is only visible in good-size telescopes. A hot blue white dwarf star near the center of the nebula is what remains of the nucleus because the gas is expelled at different times (as can be seen the image) at the end of the life of the star. The expanding nebula will fade over the next thousands of years while the central star can survive for billions of years.
