LDN 1235 - Dark Shark Nebula
Photoluminescence - Dark Nebula Complex
LDN 1235 Lynds Dark Nebula is actually located in the upper left corner of the image, but the vast nebula complex that stretches throughout this image bears an uncanny resemblance to a shark, thus it is commonly referred to as the "Dark Shark Nebula". However it is also known as the "Howling Wolf Nebula", so feel free to take your pick.
Dark nebula are opaque clouds of dust and gas in space that block the light of stars behind them. But some of the faint dust in the area of LDN 1235 may also be visible because the dust is glowing from photoluminescence.. This dust glows from the interstellar radiation field when dust particles are hit by high energy radiation. LDN1235 was determined to be about 672 light years away from Earth.
Also shown in this image are two reflection nebulae, van den Bergh 149 (vdB 149) and vdB 150. These blue nebulae can be seen on the left side of the Dark Shark at top and bottom
