DRAGOH’S HEAD NEBULA (NGC2035) (About the image: Nebula NGC2035 in narrowband. Mapped as Ha SII Ha OIII (LRGB): Taken on an RCOS 10 RC Scope at f9, SBIG STXL6303E Camera and PME mount.at telescopes Siding Spring Observatory. 40hrs of 3nm Ha bin1,4hrs of OIII bin2 and 9 hours of SII bin2. Processed with CCDstack, Star Tools and Photoshop.) The Dragon’s Head Nebula (NGC 2035), sometimes called the emission nebula, consists of gas clouds that glow due to the energetic radiation given off by young stars. This radiation strips electrons from atoms within the gas, which eventually recombine with other atoms and release light.Mixed in with the gas are dark clumps of dust that absorb rather than emit light, creating weaving lanes and dark shapes across NGC 2035. The filamentary shapes to the left in the new image from VLT are the not the results of star birth, but rather stellar death. It was created by one of the most violent events that can happen in the Universe – a supernova explosion. From looking at the image, it may be difficult to grasp the sheer size of these clouds – they are several hundred light-years across
