as15-96-13092.JPGAS 15-96-13092 - Abel, Hecataeus, Humboldt and a VERY unusual Surface Feature (Special Processing by Lunexit)56 visiteUn'immagine orbitale ottenuta da circa 115 Km di altitudine, ma che si rivela di grande bellezza e suggestione.
E non solo! Se guardate accanto al punto interrogativo potrete notare una curiosissima Surface Feature: due crateri, perfettamente circolari e perfettamente concentrici. Certo, si tratta, con ogni probabilità, di uno "scherzo" della Natura ma...Che "Scherzo"!!!MareKromium

Complimenti al Dr Barca!MareKromium

Unknown-N00111005.jpgStar-Trails? (1)56 visiteOnde evitare spiacevoli malintesi, precisiamo che gli oggetti puntiformi i quali disegnano un piccolo segmento d'arco e che, a nostro avviso, potrebbero e dovrebbero essere degli "Star-Trails", sono a Dx dell'Osservatore, in alto (il più luminoso) ed a Sx dell'Osservatore, uno in alto ed uno in basso (molto deboli). La loro incredibile somiglianza ci ha fatto anche pensare all'ipotesi per cui si tratti di un solo Star-Trail (quello luminoso a Dx) e di due riflessi del medesimo attraverso le ottiche di Cassini (i due di Sx).
L'Anomalìa del frame, infine - sia che gli Star-Trails sìano tre, sia che si tratti di uno solo -, è data dalla circostanza per cui la forma dello/degli Star-Trail/s è il chiaro indice di un movimento della Sonda Cassini. Un movimento che è avvenuto DURANTE la ripresa. Ora, a nostro avviso, è curioso che il brusco cambio di traiettoria della Sonda abbia prodotto la distorsione di un dettaglio (la stella - o le stelle - che è diventata una striscia curva) e non del corpo principale ripreso (una porzione degli Anelli di Saturno).
E' stata questa specifica considerazione che ci ha lasciati un pò perplessi sulla natura dei tre segmenti luminosi curvi (i quali, ribadiamo e chiudiamo, potrebbero e dovrebbero COMUNQUE essere delle semplici Star-Trails).
E Voi che ne pensate?

Titan-Craters-Unnamed_Craters-PIA10655.jpgTitanian Craters (Impact Craters?) - radio-image; credits: NASA56 visiteCaption NASA:"This side-by-side view shows a newly discovered impact crater (at left) compared with a previously discovered crater (at right). The new crater was just discovered by the Cassini Spacecraft's Radar Instrument during its most recent Titan flyby on May 12, 2008. This makes the fourth feature definitely identified as an impact crater so far on Titan -- fewer than 100 features are regarded as possible impacts. Compared with Saturn's other moons, which have many thousands of craters, Titan's surface is very sparsely cratered. This is in part due to Titan's dense atmosphere, which burns up the smaller impacting bodies before they can hit the surface. Geological processes, such as wind-driven motion of sand and icy volcanism, may also wipe out craters.
Both images are about 350 Km (approx. 217 miles) in width.
The crater on the right was discovered by Cassini in 2005 and is shown here for comparison. It is about 80 Km (approx. 50 miles) in diameter, with the radar illumination from above.
Called "Sinlap", this crater is estimated to be about 1300 meters (984 feet) deep.
The new feature pictured on the left, which has not been named yet, is bigger than the Sinlap Crater with a diameter of about 112 Km (approx. 70 miles).
The new crater is located at about 26° North Latitude and 200° West Longitude, in the bright Region known as Dilmun, about 1000 Km (approx. 600 miles) north of the Huygens Landing Site.
In its image, also illuminated from above, it appears slightly irregular, suggesting that it was modified after it was formed, perhaps by collapses of segments of its rim onto the floor.
The crater floor appears flat, and two small bright spots indicate a likely central peak complex.
The ejecta blanket (surrounding material) from this crater is less prominent than that of the Sinlap Crater.
The crater's more degraded character suggests it could be older than Sinlap (assuming that erosive processes are the same at both locations, which are at similar latitudes)".MareKromium
