Remarks: |
NGC 6334 (also designated Sharpless 8 or RCW 127) is an
emission nebula and an active star-forming region located in the
Carina–Sagittarius arm of the Milky Way. The nebula consists of a massive
cloud of gas and molecular material that spans a region approximately 320
light-years in diameter. Owing to its distinctive appearance, it is commonly
known as the Cat’s Paw Nebula. Although star formation is occurring throughout much of the nebula [1], numerous embedded star-forming sites have been identified, primarily through observations at infrared and radio wavelengths [2]. The inner regions are heavily obscured by dust, rendering many of these stellar nurseries invisible in optical light but accessible in the infrared. To mark the third anniversary of the James Webb Space Telescope in July 2025, NASA released new near-infrared images (capture by NIRCam) revealing that one of the “toe beans” contains smaller, sub-structures — mini-“toe beans” — harboring protostars, including one protostar that is driving a high-velocity outflow of gas and dust that produces a visible shock wave [3, 4]. X-ray sources within the nebula further reveal the presence of ten distinct star clusters associated with known infrared sources and H II regions [5]. NGC 6334 is connected to NGC 6357 by filamentary structures and likely forms a common complex with it [6]. Nearby lie the H II regions RCW 126 and RCW 128. |

Bemerkungen: |
NGC 6334 (auch Sharpless 8 oder
RCW 127) repräsentiert einen Emissionsnebel sowie eine
Sternentstehungsregion, die im Carina-Sagittarius-Arm der Milchstraße
beheimatet ist. Der Nebel wird durch eine massereiche Gas- und Molekülwolke
gebildet, die einen Raum mit einem Durchmesser von etwa 320 Lichtjahren
einnimmt. Wegen seiner Form ist er vor allem als Katzenpfoten-Nebel bekannt. |
