ESP_015900_1465_RED_abrowse-02-PCF-LXTT.jpgUnnamed Southern Crater with Gullies, Rolling Boulders and Dunes (EDM n. 2 - Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team)361 visiteCaption NASA:"This image shows a nice example of different types of Dunes in close proximity to each other: North is at roughly 03:00 in this EDM.
On either side of the Mound - which is located on the Southern End of the Crater Floor - there are different types of Dunes. On the Southern side of the mound (left side of the EDM), there are "Star Dunes" (named for the Star-like Intersections of their Crests). These types of Dunes are usually formed when the wind blows in multiple directions.
On the Northern side of the Mound (the right when looking at the EDM), there are simpler Dune shapes, forming roughly straight, parallel lines. Notice that the same side of each Dune is steeper. These are called Linear Dunes, and are formed by wind blowing mainly parallel to the direction of their Crests, probably with some variation to one side or the other that causes the asymmetrical Slopes. The Linear Dunes transition to the Star Dunes near the Mound.
Since the main factor controlling which type of Dunes are formed is the (Dominant) Winds' Direction, there must have been different Wind Directions in this area (for instance, it is very likely that significant whirlpools were caused by the wind blowing around the Mound or also when they interacted with the nearby Crater Wall).MareKromium

Moon River.jpgThe Moon over St. Lawrence River115 visiteDa "NASA - Picture of the Day" del 9 Settembre 2005:"Shortly after sunset on September 6th, sky gazers around the world were treated to a lovely crescent Moon in western skies - joined by bright planets Venus and Jupiter.
In this colorful telephoto view from near Quebec City, Canada, the Moon is nestled just above the wide St. Lawrence River. Lights on the horizon are along the river's southern shore. Also known as the evening star, Venus is at the upper left and Jupiter at the upper right, while another prominent celestial beacon, Spica, can be seen shining through the twilight below Venus.
Spica, actually a very close pair of hot blue stars some 260 LY away, is the brightest star in the constellation Virgo".

06-Oceanus Procellarum.jpgOceanus Procellarum70 visiteCaption NASA originale:"Northward oblique view of the Marius Hills and Oceanus Procellarun on the Moon taken by LO 2. The hills are named after the 41 Km diameter crater Marius, at the upper right at 11,8°N, 50,8° W and are thought to be volcanic domes, plugs and cones. Note the wrinkle ridges which also stretch across the image (Lunar Orbiter 2, frame M-213)".

Titan-PIA11594.jpgNorthern Layers (UV + Natural Colors; credits: Lunexit)53 visiteCaption NASA:"This UltraViolet view of Titan shows the moon's North Polar "Hood" (---> cappuccio) and its detached, high-altitude haze layer. See also PIA08137 to learn more.
This view looks toward the Saturn-facing side of Titan.
North on Titan is up and rotated 2° to the left.
The image was taken with the Cassini Spacecraft narrow-angle camera on Aug. 13, 2009 using a spectral filter sensitive to wavelengths of UltraViolet Light centered at 338 nanometers. The view was acquired at a distance of approx. 2,2 MKM (about 1,4 MMs) from Titan and at a Sun-Titan-Spacecraft, or Phase, Angle of 61°.
Image scale is roughly 26 Km (about 16 miles) per pixel".MareKromium
