Sharpless Sh2-36 - a molecular cloud in the constellation of the Serpent

Short description:

Like the neighbouring nebula Sh2-33 (not shown here), the molecular cloud Sh2-36 belongs to the so-called galactic cirrus and reflects the light of all the stars in the entire Milky Way. Here we are about 36 degrees above the galactic plane and can see far out into space through the thin veils of nebulae. For some years now, these extremely faint molecular clouds above and below the galactic plane have also been referred to and catalogued as "Integrated Flux Nebulae (IFN)". Besides the brightest area of the molecular cloud, the entire image field seems to be filled with extremely faint nebular veils.

Sh2-36 was shifted slightly to the right (west) in the field of view to include the galaxies NGC 6070 and PGC 57 338. NGC 6070 is assigned to type Sc according to the Hubble classification. Its apparent size is 3.6 x 1.8 arcminutes. Over its distance of nearly 100 million light years, the true size is about 100,000 light years along its long axis.
The brightness is given as 11.8 magnitudes. Together with two small galaxies (to the north) NGC 6070 A and 6070 B it forms the galaxy trio Holm 729. Directly south of NGC 6070 lies a small, irregular galaxy which is not listed in our catalogues. NGC 6070 was discovered on 3 May 1786 by Friedrich Wilhelm Herschel with his 18-inch reflecting telescope.

No information is available on PGC 57 338 other than an approximate distance of just under 70 million years and a magnitude 17.5 brightness.

We show two other molecular clouds of the Integrated Flux Nebulae type here (MW 9) and Sh2-33 here. There you will also find more detailed information about this object class.
