NGC 6334, colloquially known as the Cat's Paw Nebula, Bear Claw Nebula, or Gum 64, is an emission nebula and star-forming region located in the constellation Scorpius.[4] NGC 6334 was discovered by astronomer John Herschel in 1837, who observed it from the Cape of Good Hope in South Africa.[5] The nebula is located in the Carina–Sagittarius Arm of the Milky Way,[6] at a distance of approximately 5.5 kilolight-years from the Sun.[7]

The nebula is a high mass filamentary cloud structure spanning ~320 ly. In the visible part of the spectrum, it emits mainly in red (from hydrogen atoms) and blue (from oxygen atoms).[8] Several embedded star-forming regions have been identified from infrared and radio emissions. Four of these sites have formed H II regions.[6]
