The Helix Nebula (NGC 7293) is a large planetary nebula located in the constellation Aquarius, approx. 215 parsecs or 700 light-years distant from Earth. It was the first planetary nebula discovered to contain cometary knots, which can be seen as globs with tails around the center of the “pupil”. There are more than 20,000 cometary knots estimated to be in the Helix Nebula. These knots remain somewhat of a mystery to astronomers. NASA/Hubble/JPL/Cal Tech
