NGC 6210

The 10th magnitude NGC 6210 is a planetary nebula located northeast of Kornephoros.

This gas cloud in Hercules lies about 6500 light years away. The central star that created this planetary nebula is clearly visible at its center.

NGC 6210 was investigated with the Hubble Space Telescope because it showed evidence of unusual relative abundances of nebular gas. The resulting images showed jets of hot gas streaming through holes in an older, cooler shell of gas.
