In "Turbulent Down South",
it was stated, "It is possible that these features merged some time after this image was taken." Could these types of turbulent features actually cause the lightning to occur in Saturn's southern latitudes?
The varying degree temp inside the Herschel Crater very possibly holds the key to why the border between the colder and warmer regions form a triangular division. Possibly due to the impact depth of the Herschel Crater where an outer interior core had been breached explaining why there is a warmer region in that section of the crater.
It is very interesting in comparing the different colors of the regions to
contour of the surface area. Without the infrared colors it would be impossible to tell where the source of the radiation is coming from! Even when switching back and forth between the surface maps and the heat maps, there was no discernable pattern except that the heat that was present may have been trapped in those areas and could be read by the spectrometer more readily.
See Cassini's mini movie on "Titan's Shifting Hazes",
"where hazes appear to flow and merge".
The question is where are they merging to and where are they
merging from? Clearly, the atmosphere on Titan is not a
thanks carolyn, given that you are correct, of course, 'thermal' would not necessarily mean a volcanic eruption. Interesting also that you mention, in how the dust ring about Phoebe being of keen interest as well, I imagine that particular interest may be for a number of reasons also!
I'm not convinced that the thermal model of migrating ice is a valid explanation. It seems more plausible, based on the imagery, that there was a massive volcanic eruption which jettied massive amounts of ejecta material that covered the icy surface. If this were so, then it is doublful that the process of the evolution of dark material deposits occurring over millions of years is valid either.
The angles of deflection of the jet plumes suggest very strong evidence that there is an underground ocean and it is very close to the surface. An OL mission could be closer that we may expect after seeing these images confirming that fact.
These raw images reveal a mysterious anomaly in these plumes of Enceladus.
If there is some chance that there is organic life in the plumes then the likelihood of the existence of life close to the jets, very close to the surface is also very good. The anomaly is in the speculation. Science has yet to encounter anything like this type of geological phenomenon so what we have learned so far is only "the tip of the iceberg" on what possibilites exist and in how we can study and observe them.
Thank you again Ciclops!! In image PIA11676, (Shadows and More Shadows)
the kinks in the Encke Gap had shown a distinct height by their
shadows but Pan was not visibile in that magnification of the image.
Here, however, Pan is clearly visible and and in relation to the shadow
heights onto the A ring from the inner material band, Pan is clearly leading
the wake of the inner band by a considerable distance when compared to Daphne's
wake in the Keeler Gap where the wake is see on either side of its orbit.
The leads one to speculate as to whether vibrations in the inner band
material of the Encke Gap causes oscillations in the middle band which
then causes the shadows to appear onto the inner A rimg.
Prometheus, as captured in this image, incredibly sculpted by the
impacts into the F ring also allows for the human eye to witness
an evolving ring whose structure may be radically transformed at
some point in the distant future.
Supposing there was a collision in the D ring with a comet or asteroid with dissipation of that force extending to the inner B ring boundary, then it is possible that the visible corrugations are the recoil effect as the ring structure slowly goes back to a point of equilibrium.
When comparing the fine outer edge of the A ring with the inner edge of the F ring that the F ring is alot less clearly defined, although once might consider less dense areas of the F ring a "minor gaps" inside of the F ring. So, if the distance of Atlas to the edge of the A ring is a unit, then 2.5 of that unit would be about the distance of Atlas the the first "minor gap" of the F ring.
The point of impact with the F ring of Prometheus is moving away
from the point of impact as the ring material is deflected towards
its motion. There also appears a very suble reflected shadow at the point
of impact! If this is true then this may have been the first time Cassini has
captured one orbiting object casting 2 shadows in the same image!!
Compared to the image "Groundhog Day on Saturn" (image 3/23/09),
the elapsed time between the capture of these two images is about
19 weeks. The camera angle view here in contrast to that image is
a difference of 86 degrees. Revisiting the "Groundhog Day" photo
reveals a very thick and dark shadow of Epimetheus across the A ring
taken on 1/8/09 which was below the ring plane. Here,
at the above angle ring plane view, the shadow cast onto the A ring
is much lighter, thinner and narrow and stretches further towards the
Encke gap than the image in "Groundhog Day".
This image of Titan's atmosphere clearly shows a "uniform-ness"
to it. The halo effect also shows another very interesting
aspect where as the hazy atmosphere approaches the unlit shadow
of Titan in this image, there appears a slight divergence
away from it expanding further out.
Distant images such as this one provide clues as to where
underground oceans may have existed on the surface. The subtle
differences in shadings on Enceladus may provide much broader
insight into these facts.
When viewing the traversal of Mimas' shadow past the gaps in
the rings, what is truly remarkable is the way the shadow traverses
the first gap where it seems to "jump the gap" (center gap in image)
as compared to the traversal of the shadow in the second gap
where it seems to pass more evenly (lower right gap in image).
Interesting how in the eclipse sequence that immediately after the sequence is over and when restarting that sequence, there is a distinct and noticeable observed rotation in Mimas, even though it is very slight.
These wisps that have originated from the tectonic fractures on the surface of Dione are in some ways similar to the "tiger paw" fractures on Enceladus. From this distance, the image of Dione clearly shows those wisps as distinct from contrasting moon surface of Dione.
The path of the moonlet shows a closed path in the G ring,
however, the path in the G ring is not completely closed.
So, the question becomes at what rate (if ascertainable) is the
path of Aegaeon gaining closure in its orbit in the G ring or
by what measure is it losing it? The length of the streak
compared to the distance of a single orbit would be the
beginning of a very interesting hypothesis towards answering
A recaptured phenomenon inside the F ring where we can now witness
a future ring formation at its very beginnings. The action-reaction
collision of Prometheus with the F ring not only extracts ring material
but may as well be transforming the shape of the moon as these collisions
occur over great periods of time causing further speculation as to what
the final outcome of this event may appear as.
A very beautiful sight to see!
Saturn's shadow cast on the rings making them seem to disappear,
yet the silhouette appears against the reflected light as a reminder
to us that they are still there. A wonderful image in counterpoint!
The Saturn scene was great and so was the idea on Titan's atmosphere as a hiding place for the USS Enterprise!
Now we all know that Romulans and red matter don't mix!
Good old spock,"Live long and prosper"
A very interesting variance in the image of the atmosphere when using visible violet light instead of red, blue and green spectral filters as in the image "Hazy Ring of Titan's sky. Here, the presence of a uniform upper most atmosphere is clearly visible.
From this camera angle it appears as though there are 2 different lines of demarcation, the terminator being the first and the 2nd a lateral line in the center of the image appearing to divide Rhea between a finer surface and a rougher one.
This is a great opportunity to see Janus in orbit parallel to Prometheus.
One can really appreciate the visual confirmation of the size of Janus at
111 miles across, amazingly close to double the size compared to Prometheus' diameter of 53 miles!
Streaming material clearly seen trailing Prometheus in this fantastic
footage. Also clearly seen as well is the counter ripple effect
on the opposite end of that collision where the action-reaction
in the bright portion of the F ring showing significant wave
motion moving in opposite directions to the steamers.
One might have seen the Keeler gap at one time being much
wider in the A ring; the size and mass of Daphnis being much greater
as its orbit creates constant collisions displaced it's mass into the
Keeler gap making it narrower.
Cassini has captured in this photo what Voyager detected as a "braiding effect" F ring more than 27 years later! "The small bright dash" was called a star trail. Compared to the Cassini image one can only imagine what the sensors of Voyager had been detecting as the tortured ring or "braiding effect" of Voyager must have been filtering out what we are witnessing here as the true image.
Interesting question, are the bright spokes reflections
or are they dispersions of the bright ring matter onto the other ring bands?
The matter composition of the outer bright ring must be different then if the spokes are dispersions since there is no visible bright spoke in that outer ring!
