Summary

[edit]
Description
English: This is an almost a perfect bubble of gas cast off by a single star that has died. The bubble continues to expand; it is approximately two light years across now. Its imperfection (from our perspective) is due to photodissociation (yes... this is a real word) by interstellar UV radiation. Energetic photons from nearby bright stars decompose the gas bubble. Note the dim central blue star (a blue/white white dwarf). This image was taken as part of Advanced Observing Program (AOP) program at Kitt Peak Visitor Center during 2014.
