Innes (UOC, 1914)

Innes, in Union Observatory Circular No 20 (1914) published a note entitled "The Milky Way near Theta Ophiuchus". He wrote: "A Photograph and description of this region by Professor Barnard will be found in the Astrophysical Journal for March 1899, and another photograph will be found in the Mems. Royal Astronomical Society, LX, Plate 10.

Professor Barnard remarks that this is a remarkable region and that certain features do not seem easily explainable without the assumption that the entire groundwork of the Milky Way at this place has a substratum of nebulous matter, though he confesses that it does not look entirely like nebulosity on the plate.

Examination of plates here also renders it doubtful if the milkiness is due to real nebulosity, as in general where there is milkiness small stars can be seen; but still some milkiness remains, which, however, may be due to the crowding of still smaller stars.

With the 9-inch refractor and the short focus 3-inch finder, it is also impossible to say of the milkiness all over this region is due to nebulosity or unresolved Milky Way. Through the finder it looks like unresolved Milky Way, but if this is so, it is the only portion of the Southern Galaxy which a 3-inch fails to resolve, and that easily, into discrete stars. The small field of the 9-inch is unsuited for answering this question. In this connection reference may be made to the remarks on page 57 of the Transvaal Observatory Circular, 1910, September 26.

The remarkable "S" to the north of Theta Ophiuchus is shown on all plates examined and it is followed by a "5" which is not quite so distinct. These objects cannot be seen with the telescope.

Milky Way in Carina

Sher, D. () "Structure of the Milky Way in Carina" QJRAS, v 6, p 299-320.

"The Southern Milky Way between roughly 10 and 12 hours of RA stands out clearly to the naked eye. It is very bright and is dotted with small hazy patches which are easily resolved, with binoculars or small telescopes, into clusters of stars. In photogrpahs, the region is dominated by the great gaseous nebula NGC 3372 which covers some four square degrees near the erratically variable star Eta Carinae, and in the Mount Stromlo H-alpha Atlas the whole region is seen to be aglow with faint nebulosity."

Content of the Milky Way in Carina

Population I: clusters and nebulae

Prominent groupings of nebulosity in Carina, as well as those clusters in the region which are known to contain young stars, are listed in Table 1. Of these objets, two NGC 3576 and IC 2602 cannot for reasons discussed separately below be used in the search for possible manifestations of spiral structure in the region.

Modern observations

[amastro] Southern Milky Way

] seeing the summer Milky Way stretched overhead...

When I was in graduate school, a fellow student -- working for a PhD in astronomy -- made the trip south for some telescope time at one of the observatories in the Chilean Andes. He reported that the greate wonder of this sight was the realization that the view was obviously an edge-on spiral galaxy, with lenticular bulge, long, thin band of foreshortened disc, and obscuring dust lane, just like NGC 4565 or the Sombrero, but stretching from horizon to horizon, with the center of the galaxy (sometimes known as "downtown") in Sagittarius high overhead, all obvious to the naked eye.

-- Jay Freeman


]And yes, the Milky Way does cast a very low contrast shadow.

But of course. The whole astronomy club has seen that from here (+31.5). What is the farthest north people have noticed this?

Jeff Medkeff


The Summer Milky Way has always allowed objects to cast faint shadows from the site of the Nebraska Star Party (+42 degrees 36 min. N). I have also noted it on very clear nights from my dark sky site near my home, but nowhere near as prominent as from the NSP site near Merritt Reservoir. Clear skies to you.
