Titan-IMG001935-br500.jpgTitan during Fly-By n. 9 (Original NASA/JPL/SSI RAW b/w Frame)62 visiteOriginal caption:"This image was taken on December 26, 2005 and received on Earth December 27, 2005. The camera was pointing toward TITAN that, at the time, was approximately 57.509 Km (about 35.734 miles) away.
This image was taken using the CB3 and CL2 filters and has not been validated or calibrated".

Jupiter-PIA02865-2.JPGJupiter's clouds - 727 nnmts filter62 visiteAll the already mentined Jovian features have also been seen from ground-based telescopes, from NASA's HST and from NASA's Galileo spacecraft.
Chief among these features is the very dark patch seen in the weak methane image (619 nnmts) near the top-middle of the frame.
It is almost invisible in the next image (890 nnmts) and it appears to be composed of strands of bright clouds in this frame (727 nnmts).
This is a Region similar to the "hot spot" where the Galileo Probe entered Jupiter's atmosphere in 1995.
These images indicate that cloud cover is present at the higher altitudes but absent from the lower altitudes and this is also what the Galileo Probe found when it entered Jupiter's atmosphere.

OPP-SOL706-1P190874207EFF64KCP2439L7M1.jpgNeedles and turrets?!? - Sol 70662 visiteCerchiatura Verde: rilievi a forma di "ago" e "torretta" (o magari "piccola piramide", decidete Voi).
A giudicare dalle (lunghe) ombre che proiettano sulla superficie ci viene da pensare che si tratti di "spuntoni" che emergono dal suolo per svariati centimetri.
Sebbene non sia possibile dire ancora nulla di definitivo in ordine alla loro origine, ci sentiamo di escludere - comunque - che la loro natura possa in alcun modo essere ricondotta all'intervento di un'azione meccanica esterna ed artificiale (si pensi, ad esempio, ad una conseguenza del passaggio del Rover ovvero a qualche "disturbo" del suolo provocato dal RA).
E allora...Che cosa stiamo guardando?

SOL731-PIA06102.jpgMartian "Corals" (approx. true colors) - Sol 73162 visiteThe change in textures and the location of the basalts may be signs that Spirit is driving along the edge of a lava flow. This lava may be the same as the basalt blanketing the plains of Spirit's Landing Site, or it may be different. The large size and frothy nature of the boulders around Lorre Ridge might indicate that eruptions once took place at the edge of the lava flow, where the lava interacted with the rocks of the basin floor. Scientists hope to learn more as Spirit continues to investigate these rocks.
As Earth approaches the Chinese New Year (The Year of the Dog), the Athena Science Team decided to use nicknames representing Chinese culture and geography to identify rocks and features investigated by Spirit during the Chinese New Year celebration period. In ancient Chinese myth, FuYi was the first great emperor and lived in the East. He explained the theory of "Yin" and "Yang" to his people, invented the net to catch fish, was the first to use fire to cook food, and invented a musical instrument known as the "Se" to accompany his peoples' songs and dances. Other rocks and features are being informally named for Chinese gods, warriors, inventors, and scientists, as well as rivers, lakes, and mountains.
Spirit took this image on the rover's Martian day, or sol, 731 (Jan. 23, 2006). This is an approximate true color rendering combining images taken with the Pancam's 750-nanometer, 530-nanometer and 430-nanometer filters.

Tehys-PIA07693.jpgOdysseus62 visiteOriginal caption:"Plunging cliffs and towering mountains characterize the gigantic impact structure called Odysseus on Saturn's moon Tethys. The great impact basin lies before the Cassini spacecraft in one of the best views yet obtained.
Quite a few small craters are visible inside Odysseus (450 Km - or 280 miles across), making it clear that this is not a very young structure. However, a comparison of cratering density between the interior of Odysseus and the surrounding terrain should show whether the large basin is at least relatively young.
Odysseus lies on the Leading Hemisphere of Tethys; North is up and rotated 18° to the right.
The image was taken in polarized ultraviolet light with the Cassini spacecraft narrow-angle camera on Dec. 24, 2005 at a distance of approx. 196.000 Km (about 122.000 miles) from Tethys and at a Sun-Tethys-spacecraft, or phase, angle of 85°. Resolution in the original image was about 1 Km (3,831 feet) per pixel. The image has been magnified by a factor of two and contrast-enhanced to aid visibility".

Craters-Unnamed_Crater_with_Windstreak.JPGCrater and Windstreak in Syrtis Major Planum (Original NASA/MGS/MSSS b/w Frame)62 visiteCaption originale:"This MGS-MOC image shows an Unnamed Crater that is approx. 2 Km in diameter in South Central Syrtis Major Planum. The image also captures a portion of the light-toned Windstreak formed in the Lee (---> lato sottovento) of the Unnamed Cater. The Windstreak is likely composed of a thin coating of Dust".
Location near: 1,9° North Lat. and 294,0° West Long.
Image width: ~3 Km (~1,9 mi)
Illumination from: upper left
Season: Northern Summer

Cartwheel_5panel.jpgThe "Cartwheel Galaxy"62 visite"...La frase più ricorrente è “I virus non sono né forme di vita né materia inanimata”. Non è proprio ortodosso definire un’entità dicendo ciò che non è… Cosa se ne ricava? Non sono organismi biologici, non si riproducono e non si evolvono autonomamente, ma sono composti di materia, che però è dotata di mobilità. In parole povere, i virus sono delle macchine..."
