APOD from 2020-10-16
Planetary #Nebula Abell 78
Abell 78, a planetary nebula in Cygnus, glows with ionized atoms 5,000 light-years away. Its central star's UV light strips electrons, creating visible blue-green and red emissions. Spanning three light-years, it previews the Sun's fate in 5 billion years.
