Enceladus-N00081663.jpgFountains in the Darkness (2) - natural colors, elab. Lunexit74 visiteCaption NASA:"N00081663.jpg was taken on April 24, 2007 and received on Earth April 25, 2007.
The camera was pointing toward ENCELADUS that, at the time, was approx. 189.309 Km away, and the image was taken using the CL1 and CL2 filters.

Daphnis-PIA08924.jpgDaphnis is there...somewhere!58 visiteCaption NASA:"The presence of the tiny ring moon Daphnis is betrayed by the edge waves it creates in the Keeler Gap.
The Gap is a narrow lane, about 42 Km (26 miles) wide, in Saturn's outer A-Ring. Daphnis (7 Km, or 4,3 miles across) was discovered in Cassini spacecraft images at the same time that scientists spotted the edge waves. Researchers had suspected the presence of a moon in this gap after Pan was discovered in Voyager spacecraft images taken 25 years earlier.
This view looks toward the unilluminated side of the Rings from about 54° above the Ring-Plane.
The image was taken in visible light with the Cassini spacecraft narrow-angle camera on March 17, 2007 at a distance of approx.y 1,8 MKM (1,1 MMs) from Saturn.
Image scale is roughly 10 Km (about 6 miles) per pixel".MareKromiumApr 25, 2007

Saturn-W00027278.jpgNoise, Lack and/or Loss of signal from Saturn58 visiteEsempio di image-artifacts derivanti da "noise" ("rumore di fondo", ossìa disturbi di varia natura ed origine - macchie solari, gamma bursts, influenze elettromagnetiche et si.); "lack" of signal ("insufficienza/mancanza di segnale") e/o "loss" of signal (e cioè "perdita" di segnale).MareKromiumApr 23, 2007

Saturn-PIA08923.jpgFrom South to North81 visiteCaption NASA:"The Cassini spacecraft gazes upward at the face of giant Saturn, seeing beyond the Equator to where ring shadows fall across the bluish Northern Latitudes.
This extreme southern view looks northward from about 58° below the Ring-Plane.
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 Feb. 1, 2007 at a distance of approx. 940.000 Km (abput 584.000 miles) from Saturn.
Image scale is roughly 106 Km (about 66 miles) per pixel".MareKromiumApr 21, 2007

The_Rings-PIA08920.jpgSome in the Darkness, some in the Light...56 visiteCaption NASA:"Pan prepares to be engulfed by the darkness of Saturn's shadow, visible here as it stretches across the Rings.
When the Cassini spacecraft took a follow-up image of this same location about 50 seconds later, Pan (26 kilometers, or 16 miles across) had vanished into darkness.
This view looks toward the unilluminated side of the Rings from about 44° above the Ring-Plane.
The image was taken in visible light with the Cassini spacecraft narrow-angle camera on March 14, 2007 at a distance of approx. 1,9 MKM (about 1,2 MMs) from Pan. Image scale is roughly 11 Km (about 7 miles) per pixel".MareKromiumApr 19, 2007

Enceladus-PIA08921.jpgCosmic Shadow58 visiteCaption NASA:"Blazing like an icy torch, the plume of Enceladus shines in scattered sunlight as the moon casts a shadow onto Saturn's E-Ring. Some of the tiny ice particles erupted from the moon's South Polar Region go into Saturn orbit, forming the doughnut-shaped ring, onto which the moon's shadow is cast in this view.
The shadow of Enceladus stretches away to the upper left at around the 10 o'clock position. The Sun-Enceladus-spacecraft, or phase, angle is 164° here, with the Sun being located toward the lower right. This means that Enceladus' shadow extends toward the Cassini spacecraft -- through part of the E-Ring.
Some of the bright dots in this heavily processed view are background stars. Others are due to cosmic ray hits on the camera detector.
The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Aug. 11, 2006 at a distance of approx. 2.2 MKM (about 1,3 MMs) from Enceladus. Image scale is roughly 13 Km (about 8 miles) per pixel".MareKromiumApr 19, 2007

Japetus-N00081090.jpgThe unusual shape of Japetus... (true colors, elab. Lunexit)56 visitePianeta o Pianetoide? Sfera o Sferoide?
Il problema sembra ozioso (e, forse, lo è davvero...), ma la curiosità è grande: come mai Giapeto ha un aspetto così "angolare" - notate il suo profilo - mentre (quasi) tutte le altre Lune Maggiori di Saturno sono delle sfere decisamente belle e lineari? Forse perchè Giapeto si è raffreddato (acquisendo la sua forma finale) molto più rapidamente rispetto a quanto non abbiano fatto gli altri corpi celesti che orbitano nello Spazio di Saturno.
O forse perchè su Giapeto è accaduto qualcosa di devastante. Un evento catastrofico il quale è stato capace, oltre che di renderlo...bicolore (metà di questo mondo, infatti, è color nero, mentre un'altra metà tende al bianco/marrone, con qualche accenno di rosa), anche di "deformarlo".
O forse si è trattato di una serie di eventi ricollegabili agli stress-mareali ai quali questo piccolo mondo (al pari di tutti gli altri mondi che orbitano intorno ai Giganti Gassosi) è stato ed è sottoposto?
Difficile (se non impossibile) dare una risposta sicura. Diciamo che, nel momento in cui saremo stati capaci di individuare ed analizzare tutte le possibili situazioni (e, quindi, oltre a quelle citate, anche 100 altre...), avremo compiuto un lavoro eccellente. Per il resto, noi riteniamo che, anche possedendo una Scienza Perfetta (che comunque non abbiamo...), ad alcune domande, con ogni probabilità, una risposta netta e finale non sarà MAI possibile darla.
Forse...MareKromiumApr 17, 2007

Saturn-N00080469-02.jpgShooting Star or Alien Spaceship in-transit? (extra detail mgnf)93 visiteNota: frame ORIGINALE NASA, colorizzato da Lunexit MA NON DIGITALMENTE RIPULITO.
Notate la "tessitura" dello streak luminoso: uniforme, alquanto spessa, molto densa, ben definita e cromaticamente omogenea (e ben diversa, quindi, dagli streaks tipici dei "raggi cosmici" così come dai "graffi" e dai photo-artifacts tipicamente derivanti da perdita di segnale).Apr 08, 2007

L'interruzione nello streak è, a nostro parere e qualunque ipotesi vogliate sposare (dal bolide al raggio cosmico anomalo e dalla "nave spaziale aliena" al photographic artifact), totalmente inesplicabile.
Siamo aperti ad ascoltare e pubblicare i Vostri eventuali suggerimenti e/o le Vostre intuizioni.Apr 08, 2007
