As seen by Hubble deep space telescope
- ngc7293 (the Helix Nebula)
- here and there, right now.
- i am a leaping spiral. A planetary nebula in Aquarius about 140 parsecs (2.7 × 1015 miles or 4.3 × 1015 kilometers) distant that has a high helium abundance and the largest known diameter of any planetary nebula. That's me.
