NASA's James Webb Space Telescope imaged part of the Helix Nebula in infrared light, revealing fine structural details of curious cometary knots of gas and dust.

Key Details

• Captured high-resolution infrared details of cometary knots in the Helix Nebula (NGC 7293).
• Cometary knots have masses comparable to Earth but extend several times the size of Pluto's orbit.
• Observations support hypotheses involving stellar winds from the central star driving out existing gas.
