Hyperion-N00047027.jpgHyperion? (1)59 visiteOriginal caption:"N00047027.jpg was taken on December 23, 2005 and received on Earth December 23, 2005. The camera was pointing toward HYPERION that, at the time, was approx. 227.969 Km away.
The image was taken using the CL1 and CL2 filters".
Saranno scherzi della luce, dell'angolo di fase (o di quello di ripresa), della distanza...Chissà . L'unica cosa che a noi sembra evidente è che Hyperion, in questo frame (e nel successivo) non assomiglia per nulla al corpo celeste che avevamo già visto in passato ed ammirato durante l'ultimo fly-by di Cassini.
Diremmo che assomiglia ad Epimetheus e, comunque, ricorderete anche Voi un altro "face-change" che rilevammo qualche mese fa analizzando alcune immagini MGS di Phobos (un "cambio-faccia" del quale Vi abbiamo già parlato in passato, nella Sezione "Mars and His Moons").
Le possibili cause di questi (apparenti?) "cambi-faccia"? Ripetiamo: la luce, l'angolo di ripresa, l'angolo di fase...senza dimenticare le "sviste": nostre e non solo!

NGC-4261.jpgNGC 4261 - The "Living Core" of an active Galaxy59 visite"...Incidit in Scyllam, cupiens vitare Charybdim..."
(antico proverbio)
"...Si infranse contro Scilla, cercando di evitare Cariddi..."
ossìa: per evitare alla propria nave di soccombere nel vortice Cariddi, la portò ad infrangersi sullo scoglio Scilla. Detto per indicare l'inevitabilità del Fato e/o l'inevitabilità di un male (oggi diremmo: "al proprio Destino non si può sfuggire").

Te image was taken using the CL1 and RED filters".

KappaCrucis.jpgThe "Jewel Box" (alias Kappa Crucis)59 visiteThis image of part of the Jewel Box, an open star cluster, was acquired by the HiRISE camera, an instrument on the Mars Reconnaissance Orbiter, on December 14, 2005 as part of a calibration sequence while en route to the Red Planet. The Jewel Box was so named by Sir John Herschel because of the variety of star colors in the cluster, including the large red giant star seen near the bottom of this image. The Jewel Box, also called Kappa Crucis, is about 10 MY old, so it is much younger than our Sun which is about 4.600 MY old. This cluster lies about 7.500 LY away, so the light we see today left the stars in the Neolithic Ages of Earth, when farming was first being practiced by our ancestors.
HiRISE can image in three colors, green, red, and near-infrared, so the colors are not exactly as we see them with our eyes.
The Jewel Box cluster lies in the Crux constellation, also called the Southern Cross, the most compact constellation in the sky.

SOL700-2N188505552EFFAKFFP0783R0M1.jpgOn the way to El Dorado (2) - Sol 70059 visiteOriginal caption:" On Soles 701 to 703 (Dec. 23 to Dec. 25, 2005) Spirit completed a long Mössbauer spectrometer integration on the brushed target "Palomino" along with an overnight reading by the Alpha Particle X-Ray Spectrometer on the same target.
The PanCam took a 16-frame mosaic from Comanche over 2 Soles.
That camera and the Miniature Thermal Emission Spectrometer observed targets in the immediate vicinity with informal names like Cheyenne, Apache, Kickapoo, Chickasaw and Winnebago".

SOL711-2N189482856EFFAL02P1950R0M1.jpgMössbauer's mark - Sol 71159 visiteOriginal caption:"Right Nav-Cam Non-linearized Full frame EDR acquired on Sol 711 of Spirit's mission to Gusev Crater at approximately 11:36:32 MLT".
Cerchiatura Rossa: l'impronta sulla duna dello spettrografo Mössbauer, il cui dettaglio ingrandito ci ha dato un'idea (davvero incredibile) della reale forma e tessitura delle sabbie di El Dorado.

North_Polar_Regions-Unusual_Landscape-MGS-1.jpgIndecipherable North Polar Landscape (Original NASA/MGS/MSSS b/w Frame)59 visiteOriginal caption:"This MGS-MOC image shows a slope on which layered materials are exposed by erosion in the North Polar Region of Mars. Wind streaks are also evident in this Summertime scene.
The layers that make up the material beneath the ice of the North Polar Residual Cap are typically considered to be a mixture of some amount of dust and ice, but the proportions of these constituents are not known".
Location near: 82,6° N; 298,1° W
Image width: ~3 Km (~1,9 mi)
Illumination from: lower left
Season: Northern Summer
