Jones 1 is a type IIIb very faint planetary nebula in the constellation Pegasus and discovered by Rebecca Jones of Harvard University in 1941. The blue-green expanding outer shell of OIII ionized gas is caused by the expelled outer layers of the hot mag 16 blue star seen in the center. This occurs near the end of a stars life. Over 90% of stars will end in this phase before becoming a white dwarf while the remainder will become supernovae. Also visible at the bottom are small pockets of Hydrogen gasses.
