LDN 1235 spans about 15 light years and lies about 650 light years away toward the constellation of the King of Aethiopia (Cepheus). (NASA) LDN 1235 does indeed look like a shark (no stretched or averted imagination required).

2023年7月26日 · LDN 1235, the Shark Nebula, is a dark/reflection nebula in the constellation Cepheus. This was the most difficult deep sky object I ever had to capture since starting astrophotography, and I'll tell you all about it below!

LDN 1235 - The Dark Shark Nebula in Cepheus Sporting an uncanny resemblance to a shark, LDN 1235 is most likely an extended red emission nebula (ERE). EREs shine by photoluminescence when dust particles are hit by high energy radiation.

LDN 1235 is the densest and darkest part of the molecular cloud and very faint H-II region LBN 535. It hosts a star forming region. The age is estimated to 1-5 million years and the distance to earth between 330 and 370 pc.

2023年10月26日 · The Shark Nebula, also known as LDN 1235, is a faint cloud of interstellar gas and dust in the constellation Cepheus. It's about 15 light-years long and 650 light-years away. The Shark Nebula is not visible to the naked eye, and you won't see much through binoculars or telescopes either.

The Shark Nebula is a part of a large molecular cloud in the constellation Cepheus.Within LDN 1235 there are two blue reflection nebulae, vdB149 and vdB150, that are illuminated by nearby spectral type B8IV stars.

2022年6月15日 · The Shark Nebula (LDN 1235) is a cloud of interstellar gas and dust spanning 15 light-years head-to-tail. It’s incredibly faint, and very challenging to image from a city.

2024年11月14日 · The Shark Nebula is a swath of mostly unilluminated dark nebula spanning 15 light years across and at a distance of 650 light years from Earth. The challenge of capturing dark nebula is that you need to capture them from very dark skies away from light pollution to bring contrast to the dust from the background sky.

The shark's nose is the dark nebula LDN 1235. There is a lot of other faint nebulosity, bright stars, and a small spiral galaxy (PGC 67671, to the right of the shark's head) in this field of view.
