ZW-Pluto & Companions.jpgNix and Hydra!55 visiteDa "NASA - Picture of the Day" del 24 Giugno 2006:"Discovered in mid-2005, Pluto's small moons were provisionally designated S/2005 P1 and S/2005 P2.
They have now been officially christened Nix and Hydra.
Compared to Pluto and its large moon Charon, at 2.360 and 1.210 Km in diameter respectively, Nix (inner moon) and Hydra (outer moon) are tiny, estimated to be only 40 to 160 Km across. Pluto and Charon are bright enough to create diffraction spikes in this HST image, but Nix and Hydra are some 5.000 times fainter than Pluto and appear only as small points of light. Still, their new names are appropriate for the distant Pluto System. In mythology, Nix was the goddess of Darkness and Night and the mother of Charon, while Hydra was a nine headed monster and is now orbiting the Solar System's 9th planet.
Of course Nix and Hydra also share initials with the pluto-bound spacecraft New Horizons".

ZZ-ZZ-ZZ-ZZ-ZZ-ZZ-Nix-PIA19847-PCF-LXTT-IPF.jpgNix (Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team)58 visitePluto's tiny moon Nix (from the Latin word for "Snow"), is shown here in Absolute Natural Colors (as it was imaged by the NASA - New Horizons's Spacecraft "Ralph" instrument). This Celestial Body seems to have a global pinkish color, as well as a relatively large orange/ reddish spot that is located in its Southern Regions - perhaps, in our humble opinion, as IPF, a huge and deep Surface Depression - a "spot" that has - obviously - attracted the interest of the Mission Scientists.
The visual data shown here were obtained on the morning of July 14, 2015, and they were received on Earth on July 18.
At the time when this specific observation was taken, the NASA - New Horizons Spacecraft was about 102.000 miles (such as approx. 164.152,68 Km) from Nix. The image shows Surface Features as small as approximately 2 miles (about 3,218 Km) across on Nix, which is estimated to be about 26 miles (such as approx. 41,84284 Km) long and, roughly, 22 miles (such as about 35,40548 Km) wide.
The image (which is an Original NASA - New Horizons Spacecraft's falsely colored and NON Map-Projected frame published on the NASA - Planetary Photojournal with the ID n. 19847) has been additionally processed, magnified to aid the visibility of the details, contrast enhanced and sharpened, Gamma corrected 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 normal human eye would actually perceive if someone were onboard the NASA - New Horizons Spacecraft and then looked ahead, towards the Plutonian moon Nix), by using an original technique created - and, in time, dramatically improved - by the Lunar Explorer Italia Team.MareKromium

ZZ-ZZ-ZZ-ZZ-ZZ-ZZ-Nix.jpgFeatures of Nix120 visiteUna piccola ed affascinante luna del Sistema Plutoniano: Nix. Da notare come il cambiamento di filtro e l'esaltazione dei contrasti ci portano da una visione sostanzialmente "piatta" ad una oltremodo dettagliata e densa di punti di interesse. Per esempio: il dettaglio in basso a Dx, direi ad ore 04:30 circa, secondo Voi, di che cosa potrebbe essere rappresentativo?
Un Cratere da Impatto? Ne dubito.
Una "voragine" apertasi a causa di influssi mareali? Non ne ho idea.
Ma non posso non notare le somiglianze fra questo piccolissimo Corpo Celeste ed una altrettanto piccola luna di Urano. Indovinate quale...MareKromium
