Titan-PIA08188.jpgMellow Yellow...63 visiteCaption NASA originale:"Saturn's largest moon, Titan, peaks out from under the Planet's Rings of ice.
This view looks toward Titan from slightly beneath the Ring-Plane. The dark Encke Gap (325 Km, or 200 miles wide) is visible here, as is the narrow F-Ring.
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 narrow-angle camera on April 28, 2006 at a distance of approximately 1,8 MKM (such as 1,1 MMs) from Titan. Image scale is approx. 11 Km (about 7 miles) per pixel on Titan".

Titan-N00055564.jpgWhat's happening on Titan? (1)62 visiteCiò che Vi proponiamo in questa (lunga) sequenza di Titano potrebbe essere il frutto di una mera "misinterpretation" delle immagini (come ci direbbero i Signori del CICAP e gli Amici della NASA) oppure, come a noi piace credere, potrebbe trattarsi di un interessante fenomeno che prende le mosse e si sviluppa (o così pare) negli strati più alti dell'atmosfera di Titano.
Si tratta, in fondo, solo di un minuscolo "punto" ambiguo (9 pixels effettivi di diametro) che, nel tempo, sembra svilupparsi e che poi, improvviso come era arrivato, scompare.
Guardate ed esaminate anche Voi...
Nota: va detto, per correttezza, che la maggior parte dei frames che Vi proporremo è - purtroppo - piena di photoartifacts, anche se il "punto" che abbiamo cerchiato, a differenza degli altri difetti, si mantiene in una posizione che noi definiamo "coerente", nel tempo.
Caption NASA:"N00055564.jpg was taken on March 20, 2006 and received on Earth March 20, 2006. The camera was pointing toward Titan that, at the time, was about 972.114 Km away. The image was taken using the P120 and UV3 filters".

The image was taken using the P60 and UV3 filters".

Titan-PIA08211.jpgIn the lights: Titan, Janus and the Rings...62 visiteCaption NASA:"Dazzling Titan glows with a 360° Sunset as light scatters through its very extended atmosphere. Some structure is visible in the hazes of the Northern Polar Hood.
To the left is Janus (181 Km, or 113 miles across), far off on the opposite side of the Ring-Plane. The Rings show their unlit side to Cassini, as the spacecraft viewed them from slightly above the ringplane.
A world with strikingly Earth-like physical processes, frigid Titan is Saturn's largest natural satellite, at 5.150 Km (about 3.200 miles) across. Titan's image is saturated (cosiddetto "effetto goccia di luce") at the 5 o'clock position.
The view was acquired in visible light with the Cassini spacecraft narrow-angle camera on June 2, 2006 at a distance of approx. 2,3 MKM (such as about 1,5 MMs) from Titan and at a Sun-Titan-spacecraft, or phase, angle of 163°. Cassini was 3,7 MKM (about 2,3 MMs) from Janus. Image scale is roughly 14 Km (about 9 miles) per pixel on Titan and approx. 22 Km (about 14 miles) on Janus".

00-Titan.JPGTitan in possible True Colors (credits: NASA)62 visiteAttraverso l’oculare di un (anche) modesto telescopio, Titano, il più grande satellite naturale del pianeta Saturno, appare come un corpo puntiforme che splende debolmente di un delicato color giallo-pallido.
Si tratta di un oggetto celeste reso affascinante dalla sua posizione – apparentemente assai prossima – rispetto al Gigante Anellato (la sua distanza angolare da Saturno non supera mai i 20 raggi saturniani), ma certo non si può dire che Titano, in sé, riesca a suggerire particolari interessi e curiosità visive, anzi: nessun rilievo superficiale di questo Mondo, infatti, risulta discernibile nelle osservazioni effettuate da Terra (nemmeno usando le più sofisticate ed avanzate tecniche fotografiche) e, come abbiamo appreso grazie alle immagini ottenute dalle Sonde Voyager prima e dall’Orbiter Cassini poi, anche da distanza (relativamente) ravvicinata questo mondo risulta alquanto indecifrabile (anche se occorre dire che, già dalla metà degli Anni ’70, l’effettuazione di una serie di osservazioni ripetute di Titano – effettuate usando i più grandi telescopi terrestri al tempo disponibili – aveva, peraltro correttamente, suggerito agli Astronomi una sostanziale NON uniformità, in termini di albedo, della sua superficie la quale venne ben interpretata, sin d’allora, come indice della possibile presenza di aree superficiali sensibilmente disomogenee ed equiparabili a continenti).

Titan-PIA11479.jpgTitan (Natural Colors; credits: Lunar Explorer Italia)61 visiteCaption NASA:"Caption NASA:"This Cassini Spacecraft image affords a view of Titan's South Polar Region: an area home to one of Titan's hydrocarbon "Lake Districts".
Titan's South Pole is illuminated to the right of the Terminator, near the bottom of the visible disk. The dark area near the bottom, in Titan's Mid-Southern Latitudes, is Mezzoramia.
The wider, darker region near the Equator is named Senkyo. A "Lake District" (see also PIA11147) containing what scientists believe are lakes of hydrocarbons has been found surrounding Titan's South Pole.
Lit Terrain seen here is on the Saturn-facing Side of Titan. North on Titan is up and rotated 27° to the right.
The image was taken with the Cassini Spacecraft narrow-angle camera on Feb. 15, 2009 using a spectral filter sensitive to wavelengths of Near-InfraRed Light centered at 938 nanometers. The view was acquired at a distance of approx. 1,2 MKM (such as about 746.000 miles) from Titan and at a Sun-Titan-Spacecraft, or Phase, Angle of 55°.
Image scale is roughly 7 Km (about 4 miles) per pixel".MareKromium

Titan-PIA11501.jpgSouth Polar "Tropospheric Cloud Streaks" (Natural Colors; credits: Lunar Explorer Italia)61 visiteCaption NASA:"The Tropospheric Clouds seen in the lower left of the image are located at 45 to 55° South Latitude on Titan, and the streaks of the clouds are oriented East-West.
This view looks toward the South Pole of Titan. The South Pole lies near the Terminator about a quarter of the way inward from the Planet's limb at the bottom of this image. Lit terrain seen here is on the Leading Hemisphere of Titan.
This image was taken with the Cassini spacecraft narrow-angle camera on March 24, 2009 using a spectral filter sensitive to wavelengths of near-InfraRed Light centered at 938 nanometers. The view was obtained at a distance of approx. 1.1 MKM (about 684.000 miles) from Titan and at a Sun-Titan-Spacecraft, or Phase, Angle of 78°. Image scale is 7 Km (a little more than 4 miles) per pixel".MareKromium
