Volcanic_Features-Caverns-PIA09929-00.jpgOn the Northern Slope of Arsia Mons: candidates Cavern Entrance (1)73 visiteCaption NASA:"Seven very dark holes on the North Slope of Arsia Mons (about 9° South Lat. and 239° East Long.) have been proposed as possible cave skylights, based on day-night temperature patterns suggesting they are openings to subsurface spaces. These 6 excerpts of images taken in visible-wavelength light by the Thermal Emission Imaging System (THEMIS) camera on NASA's Mars Odyssey orbiter show the 7 openings.
Solar illumination comes from the left in each frame.
The features have been given informal names to aid comparative discussion. They range in diameter from about 100 meters (328 feet) to about 225 meters (738 feet).
The candidate cave skylights are (A) "Dena", (B) "Chloe", (C) "Wendy", (D) "Annie", (E) "Abby" (left) and "Nikki", and (F) "Jeanne."
Arrows signify North and the Direction of Illumination".MareKromium

Candor_Chasma_Region-00.jpg"Noise" over Candor Chasma? (CTX Frame - Saturated Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team)55 visiteUn'immagine intrigante e suggestiva che ci mostra una moltitudine di rilievi situati nella Regione dell'Abisso di Candor (Candor Chasma, appunto) ed un "disturbo" del frame probabilmente riconducibile a quell'artefatto fotografico noto come "noise" (rumore --> disturbi intervenuti durante la trasmissione del segnale video i quali hanno finito con l'intaccarne la qualità).
Per gli Appassionati di Ufologia: stressando il frame ed ingrandendo i "puntini luminosi" che dovrebbero costituire l'image artifact sopra menzionato, non possiamo fare a meno di pensare ai "flaps" occorsi sopra il Messico i quali, come ci hanno mostrato svariati filmati, si sono risolti nel sorvolo di alcune Regioni da parte di centinaia (o forse migliaia) di sfere color argento.
Stesso fenomeno o semplice somiglianza? Secondo noi la somiglianza è casuale e quello che vediamo in questo frame è effettivamente un image artifact diffuso, ma la Verità, come sempre, non la sa nessuno...
O quasi.MareKromium
