This picture (which is a NASA - Original Mars Reconnaissance Orbiter NON-Map Projected CTX b/w frame identified by the serial n. ESP_025557_1705) has been additionally processed and then colorized in Absolute Natural Colors (such as the colors that a human eye would actually perceive if someone were onboard the NASA - Mars Reconnaissance Orbiter and then looked down, towards the Surface of Mars), by using an original technique created - and, in time, dramatically improved - by the Lunar Explorer Italia Team.MareKromium

Saturn-North_Pole-PIA14945-PCF-LXTT-IPF.jpgNorth Polar Spring (Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga/Lunar Explorer Italia/Italian Planetary Foundation)68 visiteThe North Pole of the Gas-Giant Planet Saturn, now illuminated by the fresh lights of the incoming Spring, is finally revealed in this image taken by the NASA - Cassini Spacecraft on November 27, 2012. As you know, the North Pole of Saturn has been hiding for a long time from the gaze of the Cassini's Imaging Cameras, and that circumstance was due to the fact that it was still Wintertime in (and therefore a deep darkness all over) the Northern Hemisphere of the Ringed Planet when the Spacecraft arrived in the Saturnian System in the AD 2004.
A Hurricane-like Storm circling Saturn's North Pole at about 89° North Latitude is also well visible inside the famous "Hexagon" Feature, which scientists think is a wandering Jet-Stream that whips around the North Pole of Saturn at a relatively constant mean speed of about 220 miles per hour (such as a little more than 354 Km per hour). Such a Jet-Stream it is folded into a six-sided shape because the Hexagon is a Stationary Wave that guides the path of the Gases existing inside the Jet itself. The Hexagon borders occur at about 77° North Latitude and the Feature is wider than two (flat) Earths. Last, but not least, a little section of the Rings of Saturn can also be seen in the upper right corner of the image.
This frame was acquired with the NASA - Cassini Spacecraft Wide-Angle Camera at a distance of approximately 260.000 miles (such as a little more than 418.000 Km) from the top of the Saturnian Clouds and at a Sun-Saturn-Cassini Spacecraft, or Phase, Angle of 96°. Image scale is roughly 18 miles (such as 28,968 Km) per pixel. For another image of the Hexagon and the Hurricane-like Storm that encircles the North Pole of Saturn, please refer to the APOD of December, 29, 2012.
This frame (which is a NASA - CASSINI Spacecraft Original Natural Color frame published on the NASA - Planetary Photojournal and identified by the serial n. PIA 14945) has been additionally processed, magnified, contrast enhanced and then re-colorized, according to an educated guess carried out by Dr Paolo C. Fienga (LXTT-IPF), in Absolute Natural Colors (such as the colors that a human eye would actually perceive if someone were onboard the NASA - Cassini Spacecraft and then looked outside, towards the North Pole of Satun), by using an original technique created - and, in time, dramatically improved - by the Lunar Explorer Italia Team. Different colors, as well as different shades of the same color, mean, among others, the existence of different Elements in the Upper Atmosphere of Satun, each having a different Albedo (---> Reflectivity) and Chemical Composition.MareKromium

ZZ-ZZ-ZZ-ZZ-ZZ-ZZ-ZZ-Pluto-PIA19936-PCF-LXTT-IPF.jpgSputnik Planum and Surroundings (Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team) 68 visiteThis beautiful picture is, in fact, an Image-Mosaic which has been created by using (---> putting together) several High-Resolution frames of the Dwarf-Planet Pluto, that were all sent back to Earth by the NASA - New Horizons Spacecraft in the days going from September 5 to 7, 2015. The mosaic, as you can easily see, is dominated by the bright Icy Plains which have (so far) been informally named Sputnik Planum.
However, the Image-Mosaic also features (---> shows) a tremendous variety of other (and, Geologically speaking, completely different) Landscapes that surrounds Sputnik Planum (---> such as a number of areas of Pluto which we have already shown you in the APODs of Semptember 14, 15 and 16, 2015).
The smallest visible Surface Features here are roughly 0,5 miles (such as approx. 0,80467 Km) across, and the Mosaic - in its entirety - covers a Plutonian Region that is about 1000 miles (such as, roughly, 1609,34 Km) wide. The images forming the Mosaic were taken as the NASA - New Horizons Spacecraft flew past Pluto on July 14, 2015, from a distance of about 50.000 miles (such as approx. 80.467 Km).
The image (which is an Original NASA - New Horizons Spacecraft's b/w and NON Map-Projected frame published on the NASA - Planetary Photojournal with the ID n. PIA 19936) has been additionally processed, magnified to aid the visibility of the details, contrast enhanced and sharpened, Gamma corrected and then colorized (according to an educated guess carried out by Dr Paolo C. Fienga-LXTT-IPF) in Absolute Natural Colors (such as the colors that a normal human eye would actually perceive if someone were onboard the NASA - New Horizons Spacecraft and then looked ahead, towards the Dwarf-Planet Pluto), by using an original technique created - and, in time, dramatically improved - by the Lunar Explorer Italia Team.MareKromium

ZZ-ZZ-ZZ-ZZ-ZZ-ZZ-ZZ-Pluto-PIA19948-PCF-LXTT-IPF.jpg15 Minutes after Pluto - Large View (Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team)68 visiteJust 15 minutes after its Closest Approach to Pluto - which occurred on July, 14, 2015 -, the NASA - New Horizons Spacecraft looked back toward the Sun and captured this simply beautiful Near-Sunset View of the rugged, Icy Mountains and flat Ice Plains extending all over around and to Pluto's Horizon and Terminator Line.
The smooth expanse of the Icy Plains which have (so far) been informally named Sputnik Planum (watch to the right - Dx - of the picture) is flanked to the West (left - Sx) by rugged Mountains that reach up an altitude of approx. 11.000 feet (such as, roughly, 3352,8 meters), including the (even in this case, so far) informally named Norgay Montes (visible in the foreground) and the Hillary Montes, visible on the Skyline (---> Outer Edge/Horizon of Pluto). To the right (Dx), such as to the East of Sputnik Planum, some rougher (---> highly irregular) Terrain is cut by - what they appear to be - Glaciers. Furthermore, the backlighting, highlights several Layers of Haze in Pluto's tenuous - but quite uniform and highly distended - Atmosphere.
This image was taken from a distance of about 11.000 miles (such as approx. 17.702,74 Km) from the Surface of Pluto; finally, the whole scene is roughly 780 miles (about 1.255,2852 Km) wide.

Helene from Voyager 2.jpgHelene from Voyager 267 visiteAnche per "Helene" vale quanto detto per Epimetheus e le altre Lune Minori di Saturno: forme irregolari e dimensioni davvero modeste. Schegge (frammenti) di corpi più grandi i quali, oggi, ci rammentano catastrofi planetarie occorse in epoche remote, o dei semplici KBO, catturati da Saturno mentre si trovavano a passare nelle prossimità del Gigante Anellato?
Voi che dite?
