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.
