The Bat Nebula – NGC 6695 is part of the Veil Nebula of a residual supernova in the constellation of the Cyngus. The supernova explosion that created the Veil Nebula occurred 5,000 to 10,000 years ago. It is 2400 light-years from our Earth. The eastern part of this residual supernova is also called the bat nebula.
NGC 6995 was discovered by John Herschel in 1825.
