Next is Ngc 1512, compare it with the M94 red version above to see
the symmetric principle(s) similarities of these 'starburst' galaxy
images.
Both red and magenta views of M94 are scaled (in the composite made
by astronomers) to approximately the same size (the red is slightly
smaller). This rotated view next, shows that the outer red rim is not
quite the same diameter as the white ring in the ultra violet (magenta)
image.
THE M94 SUPERSIZE
A view from a Dss historic image has a surprise. A greater
size surrounds the main brightly lit rings of arms, the greater
size extends on a slanted axis from lower left to upper right across
the galaxy so this will be its larger oblong elements according to
our perceptual view of it in deep space.
Slashes seen to the left of M94 in deep space expand into two
interesting objects.
DEEP SPACE HIDDEN OUTER RING
Here is what seems a faintly glowing outer ring around M94, in a view
that is still dull after enhancements. Next
are enhancements revealing (by circumventing glow) that a very large
structure is out there, perhaps this outer ring
is the circumpherence of a gravity well surrounding M94.
On the other hand, the outer ring tologically more resembles extra large
arms. If you are able to superimpose the next two images together in
overlay, you will see that the bright center is offset to the left, it
does not perfectly fit in midcenter within the outer ring. Offset centers
are not unusual in ring shaped galaxies.
I take one long Moonwalking step backward wearing size 26 shoes, in
assuming that the mushie smurr the Dss jukebox dished out as M94 is
the whole show seen by Hubble, and by the ultra violet astronaught.
There is not enough distinction in the Dss version to decide no brainer
if the jukebox version is only the middle and not the ultra violet ring
until enhanced. Here is an attempt at comparative scale, looking for
features in the Dss image that are obvious in the Ultra violet and
infra red views.
***
In fact, it seems the Dss jukebox did dish only the concentrated x-ray
hot thing known as the starburst ring to
astronomers, in which case the mighty outer
donut is another ring of action wayyyy out there happily throbbing its
pulsations as part of an overall master galaxy known as M94, the outer
ring at long distance from center discovered here
in Galaxies in Chaos.
MYSTERIOUS OVAL IN DEEP SPACE NEAR M94
A second surprise (the first is the major outer
ring) are two partial ovals which turn up under very high
enhancement by Histogram Equalize. The partial
ovals are irregular as in bow shaped, so cannot be hems of telescope
light circles.
The ovals are seen more clearly in 'preview' images screen captured in a
PC graphics editor.
The larger oval turned up in the upper left corner of
this shifted view, and here is what appeared
when the glimpse was shifted over and down to central screen. Here is
the original Dss 60x60 image with M94 a mere
dull no-show small smurr in center screen.
Let's move on.
TWO SLIM STREAKS NEED EXPLAINING
In the next image (from this Dss image),
the small slash is at further depth and a different angle its right
end dipping away, whereas the right end of the large slash is angled
sharply toward us in deep space.
Those twin slashes need explaining. Even if nothing but image flaws,
such flaws as this need explaining - what - how. These slashes seem
formed, the larger has a broom tail extending at the upper left end,
and turns away abruptly at the closer near end (at the right).
There seems nothing artificial no thin perfectly straight scrapes no
nose hairs no linen fibres. These are what the slashes are not. What
the bigger seems, is a bi-laterally asymmetric
galaxy seen on edge, a faint show of its strongest radiations glimpsed
through obscuring haze of kind which so dramatically dims M94.
Suspect these are galaxies. Sharp clues are
as follows, seen only in 3D by overlaying the two images together - the
small slash is far distant back in deep space, very far, and the larger
slash has a sharp elbow jog, which is common
in galaxy arms and rims, and cannot be made by some mad astronomer's
razor blades on a film negative or whipping the mouse around on an
image altering computer. In fact the upper broom tail, which bends this
way, has parallel layers, as seen in the low resolution zooms enhanced
above as best as I can get them (see the three 'slash' images above again).
The twin slashes are very large in deep space perspective but not
knowing where they are or what they are rules out that they compare
in size to the optically bright part of M94.
In fact, you might almost think the larger coherental is a sneaky
Dss version of this AAT galaxy but, no
it is not, even though the AAT galaxy (Ngc 3628) has rudimentary
striates in its outer left hidden
dim media flange.
ANOTHER SLASH IN THE SOMBRERO GALAXY HALO
Another slash has been spotted, in the halo of the
Sombrero galaxy. It may be a galaxy seen on edge through haze. If not,
it definately needs explanation since this is in an ESO image where image
flaw on a negative is impossible since only digital camcord techniques
are used for ESO images.
