Saturn in the Cassini era has proved to be an unexpectedly colorful place,
compared to the browns and golds imaged by the two Voyager spacecraft.
Saturn is headed toward equinox in 2009, followed by springtime in the
northern hemisphere. Having a spacecraft in orbit while such changes occur
will be of great benefit in scientists' quest to understand the
atmospheres of the giant planets.
The planet's oblate, or squashed, shape is clearly visible in this view.
The low-density planet rotates so fast (in about 10.5 hours) that it
flattens out slightly around its middle. The bluish tint of the northern
latitudes is presumed to be a seasonal effect, and will likely disappear
entirely as the north receives increasingly greater amounts of sunlight.
Images taken using red, green and blue spectral filters were combined to
create this natural color view. The images were obtained with the Cassini
spacecraft wide-angle camera on July 29, 2007 at a distance of
approximately 3.1 million kilometers (2 million miles) from Saturn. Image
scale is 184 kilometers (115 miles) per pixel.

I've been wanting to try this for a while since I saw it in a magazine. This is my first attempt at Oil & Water shots.
Flying over the unlit side of Saturn's rings, the Cassini spacecraft
captures Saturn's glow, represented in brilliant shades of electric blue,
sapphire and mint green, while the planet's shadow casts a wide net on the
rings.
This striking false-color mosaic was created from 25 images taken by
Cassini's visual and infrared mapping spectrometer over a period of 13
hours, and captures Saturn in nighttime and daytime conditions. The visual
and infrared mapping spectrometer acquires data simultaneously at 352
different wavelengths, or spectral channels. Data at wavelengths of 2.3,
3.0 and 5.1 microns were combined in the blue, green and red channels of a
standard color image, respectively, to make this false-color mosaic.
This image was acquired on Feb. 24, 2007, while the spacecraft was 1.58
million kilometers (1 million miles) from the planet and 34.6 degrees
above the ring plane. The solar phase angle was 69.5 degrees. In this
view, Cassini was looking down on the northern, unlit side of the rings,
which are rendered visible by sunlight filtering through from the sunlit,
southern face.
On the night side (right side of image), with no sunlight, Saturn's own
thermal radiation lights things up. This light at 5.1 microns wavelength
(some seven times the longest wavelength visible to the human eye) is
generated deep within Saturn, and works its way upward, eventually
escaping into space. Thick clouds deep in the atmosphere block that light.
An amazing array of dark streaks, spots, and globe-encircling bands is
visible instead. Saturn's strong thermal glow at 5.1 microns even allows
these deep clouds to be seen on portions of the dayside (left side),
especially where overlying hazes are thin and the glint of the sun off of
them is minimal. These deep clouds are likely made of ammonium
hydrosulfide and cannot be seen in reflected light on the dayside, since
the glint of the sun on overlying hazes and ammonia clouds blocks the view
of this level.
A pronounced difference in the brightness between the northern and
southern hemispheres is apparent. The northern hemisphere is about twice
as bright as the southern hemisphere. This is because high-level, fine
particles are about half as prevalent in the northern hemisphere as in the
south. These particles block Saturn's glow more strongly, making Saturn
look brighter in the north.
At 2.3 microns (shown in blue), the icy ring particles are highly
reflecting, while methane gas in Saturn's atmosphere strongly absorbs
sunlight and renders the planet very dark. At 3.0 microns (shown in
green), the situation is reversed: water ice in the rings is strongly
absorbing, while the planet's sunlit hemisphere is bright. Thus the rings
appear blue in this representation, while the sunlit side of Saturn is
greenish-yellow in color. Within the rings, the most opaque parts appear
dark, while the more translucent regions are brighter. In particular, the
opaque, normally-bright B ring appears here as a broad, dark band
separating the brighter A (outer) and C (inner) rings.
At 5.1 microns (shown in red), reflected sunlight is weak and thus light
from the planet is dominated by thermal (i.e., heat) radiation that wells
up from the planet's deep atmosphere. This thermal emission dominates
Saturn's dark side as well as the north polar region (where the hexagon is
again visible) and the shadow cast by the A and B rings. Variable amounts
of clouds in the planet's upper atmosphere block the thermal radiation,
leading to a speckled and banded appearance, which is ever-shifting due to
the planet's strong winds.

Axel and Elijah spend an afternoon talking and reminiscing about their lives.
Elijah snow comes into a hospital room to talk to the superhuman Doctor Axel Brass or Doc Brass who has recovered except his deformed legs. It seems that Doc Brass was unaware of the true year when he was first recovered by Planetary.
Brass then briefly reflects on his life and his past and how he was special, it is revealed that his family some of the greatest minds of intellectual Europe dating back to the French Revolution predicted the coming of a superhuman and created a new kind of diet a new learning system original exercise regime and applied it to their own children. It also is shown that Brass' parents were brother and sister one of the few things in life that disturbs him.
Elijah then puts in a tape in the tv of Jenny Sparks someone the two of them have met in Brass' room the two reminisce of a common
acquaintance John Cumberland who died saving a planet in outer space Cumberland's death makes Brass remember a battle he had with Neo-Arachnids beneath Chicago.
The two then leave the office and go outside to speak Snow says he doesn't trust Planetary and then asks about one of Brass' former allies who died in their last battle, Hark. It is shown that Hark was an enemy to Britain than America but Brass pleaded with Hark and convinced him to change his ways. It is also shown that Hark's daughter Is Anna Hark of the Hark Corporation and may be very manipulative.
Soon after Brass and Hark teamed up to make the world a better place they were joined by others who shared the two's goal including Secret Agent Jimmy, the challenger of unknown things the Aviator, Kevin sack Lord Blackstock an English lord raised in the jungles of Africa, the inventor-adventurer Edison, and the Dark Millionaire a man committed to fighting crimes in all its forms. All of them banded together to save the world even battling a group of Demonites. The group of men then became disillusioned at the violence of the world and decided to make the world a better place. At the end of 1944 Doc Brass and his allies prepared to gather for what would be their final meeting.
Doc Brass then tells an irrated Snow who is angry Planetary has not helped him understand life better that if you save the world it will repay you. The two then light up cigarette and Brass tells Snow to get his questions first before he looks for answers Elijah Snow's question seems to be who is the Fourth Man the benefactor of Planetary. Brass then tells Snow he would have liked teaming with him and his men in the thirties Snow responds regretfully he was busy.

Saturn's peaceful beauty invites the Cassini spacecraft for a closer look
in this natural color view, taken during the spacecraft's approach to the
planet. By this point in the approach sequence, Saturn was large enough
that two narrow angle camera images were required to capture an end-to-end
view of the planet, its delicate rings and several of its icy moons. The
composite is made entire from these two images.
Moons visible in this mosaic: Epimetheus (116 kilometers, 72 miles
across), Pandora (84 kilometers, 52 miles across) and Mimas (398
kilometers, 247 miles across) at left of Saturn; Prometheus (102
kilometers, 63 miles across), Janus (181 kilometers, 113 miles across)
and Enceladus (499 kilometers, 310 miles across) at right of Saturn.
The images were taken on May 7, 2004 from a distance of 28.2 million
kilometers (17.6 million miles) from Saturn. The image scale is 169
kilometers (105 miles) per pixel. Moons in the image have been brightened
for visibility.

Wow - 2012 - 2013 have been great for sky watching. Starting with the Total Eclipse of the sun is Nov. 2012 to the two meteor showers in December that peaked at the same time; then to the PanStarrs Comet this year and so far there have been two lunar eclipses. Now this weekend has been a wonderful planetary conjunction of Mercury (hard to see under normal conditions), Mars, and Venus. Oh yes, in February was another rare opportunity to see Mercury.
If you're interesting - shortly after the sun goes down and while the sky is still a bit light, you'll see the first planet appear and as the sky grows darker the second and third. They'll be a bit closer in appearance tomorrow night. At about a 20 deg. angle off the Western horizon tonight.
Amazing! I can't wait to see the comet at the end of 2013.

Jupiter's faint ring system is shown in this color composite as two light orange lines protruding from the left toward Jupiter's limb. This picture was taken in Jupiter's shadow through orange and violet filters. The colorful images of Jupiter's bright limb are evidence of the spacecraft motion during these long exposures. The Voyager 2 spacecraft was at a range of 1,450,000 kilometers (900,000 miles) about two degrees below the plane of the ring. The lower ring image was cut short by Jupiter's shadow on the ring.

Astronomers have long known that Saturn's rings reflect sunlight most
strongly when Earth is located directly between Saturn and the sun. Flat,
shiny surfaces (like a mirror or a pond) can appear particularly bright
when light reflects off them in a certain direction. Scientists call this
"specular reflection," from the Latin word for mirror. However, even rough
surfaces, like those of Earth's moon or Saturn's rings, can appear bright
when the source of light is directly behind the observer's head, no matter
what the orientation of the surface is. This latter phenomenon is known as
the "opposition effect." Spectacular examples include the eyes of a cat,
which seem to glow brightly when they are illuminated by a flashlight, or
highway signs and reflectors that "light up" when they are caught in a
car's headlights.
On Aug. 16, 2006, as the Cassini orbiter flew directly between the sun and
Saturn, its Visual and Infrared Mapping Spectrometer captured a sequence
of images that vividly show this opposition brightening. Combined here
into a mosaic, the images show -- from left to right -- a small, bright
spot moving from the outermost B ring across the Cassini Division and all
the way across the A ring. In each image, this spot is centered on the
point in the rings directly opposite the sun. Theoretical models for the
opposition effect suggest that it can be explained by light being
scattered several times within the surfaces of individual, transparent,
icy ring particles on scales of about 40 micrometers, or 1/500th of an
inch. Similar effects are seen in laboratory studies of bright,
finely-textured material such as snow or sugar crystals.
In this mosaic, blue colors highlight the icy rings (2.35 microns), green
represents sunlight reflected by the clouds of Saturn (2.86 microns) and
red depicts thermal emission from the planet's interior (5.02 microns).
The rings were observed while they were in front of the planet, producing
a complex interplay of sunlight reflected from the rings and the shadows
cast by the rings on the cloud tops of Saturn. The yellow-green sunlit
clouds of Saturn are seen in the upper right corner of the mosaic beyond
the outer edge of the A ring, and also through the 4,000-kilometer-wide
(2,400 mile) Cassini Division in the left third of the mosaic. (Yellow
indicates a mixture of reflected sunlight and thermal emission.) The
shadowed regions of the planet, on the other hand, appear deep red because
only thermal emission produced deep inside Saturn itself is visible.
At exact opposition, the shadows of the rings are hidden behind the rings
themselves, but away from this point shadows can be seen peeking out from
behind the edges of the A and B rings into the Cassini Division, as well
as beyond the outer edge of the A ring. If one looks closely, one can even
trace the A ring's shadow behind the partly transparent A ring, as a faint
purple band. Within this band, a thin blue-green line crossing obliquely
behind the A ring is caused by sunlight passing through the narrow Encke
Gap in the outer A ring.
The Cassini spacecraft was at a distance of 254,000 kilometers (157,800
miles) from the center of Saturn when these images were taken, while the
opening angle of the rings to the sun was 16.3 degrees. The image scale at
the rings is approximately 70 kilometers (40 miles) per pixel. All nine
images were taken over a period of 27 minutes, and the vertical dimension
of the mosaic is 1.8 degrees.

Brooding Saturn seems to be missing its rings, but their shadows on the
planet betray their presence. The inner rings are in fact contained within
this scene, but they are so tenuous as to be nearly invisible.
This view looks toward the unilluminated side of the rings from about 52
degrees above the ringplane. Some motion is apparent in Saturn's clouds
between the exposures used to create this color composite, as evidenced by
the 'rainbow' effect seen here and there across the face of the planet.
Images taken using red, green and blue spectral filters were combined to
create this natural color view. The images were taken with the Cassini
spacecraft wide-angle camera on April 5, 2007 at a distance of
approximately 1.5 million kilometers (900,000 miles) from Saturn. Image
scale is 84 kilometers (52 miles) per pixel.

Visit to Thor's helmet - an earlier "quickie" (only 36 min exp) in January and last night with the Meade. Elements etc conspiring against me! - pesky wind caused the loss of 60 of the 136 exposures - vibrations, had to lose the dew shield at some stage... (The Meade 14" is definitely too HEAVY for the Meade LX850 mount...) - but still got an hour or so total exposure.
