TheGreyIllusion.JPGThe "Same Color Illusion"60 visiteDa "NASA - Picture of the Day" del giorno 4 Ottobre 2009:"Are square A and B of the same color?
They are.
The above illusion, called the "Same Color Illusion", illustrates that purely human observations in science may be ambiguous or inaccurate. Even such a seemingly direct perception as relative color. Similar illusions exist on the sky, such as the size of the Moon near the Horizon, or the apparent shapes of astronomical objects. The advent of automated, reproducible, measuring devices such as CCDs have made science in general and astronomy in particular less prone to, but not free of, human-biased illusions".MareKromium

SOL2047-MOSAIC-MF.jpgUnusual Phenomenon in the Plain of Gusev - Sol 2047 (Image-Mosaic; credits: Dr M. Faccin)60 visiteQuesto spettacolare Fotomosaico ci aiuta a capire meglio quello che sta succedendo: non ci sono, infatti (e come dianzi si accennava), solo l'Anomalìa Luminosa ed il "flash" (che, ribadiamo, NON è un Raggio Cosmico nè un Image-Artifact) a "catturare" l'attenzione di Spirit, ma anche un qualcosa che risulta visibile solo una volta processate le immagini in maniera tale da esaltare i contrasti e quindi "spingere" la capacità visiva delle fotocamere (e dei nostri occhi assieme ad esse) OLTRE lo Spettro della Luce Visibile.
Spirit, come potete vedere nella porzione di frame definita da un rettangolo, sta catturando ANCHE un curioso fenomeno il quale sembra risolversi in una sorta di Vortice.
Un Vortice invisibile - o quasi - fatto di Luce (che splende oltre lo Spettro del Visibile) e, forse, di materiali sottilissimi il quale potrebbe essere, in qualche modo, la causa e/o la concausa del "flash".
Che cosa stiamo osservando, realmente?MareKromium

Solar_Prominence-STEREO.jpgHuge Solar Prominence60 visiteCaption NASA:"What does a Solar Prominence look like in three dimensions? To help find out, NASA launched the STEREO satellites to keep a steady eye on the Sun from two different vantage points.
The STEREO satellites orbit the Sun nearly along Earth's orbit, but one (dubbed "Ahead" ---> Avanti) currently leads the Earth, while the other (dubbed "Behind" ---> "Dietro") currently trails. Three weeks ago, a powerful Prominence erupted and remained above the Sun for about 30 hours, allowing the STEREO satellites to get numerous views of it from different angles.
Pictured above is a High-Resolution image of the event from the STEREO "Ahead" satellite.
A video of the Prominence erupting as seen from both Spacecrafts can be found at http : // www . youtube . com / watch?v = _RjswBx6ysQ.
The unusually quiet nature of the Sun over the past two years has made large prominences like this relatively rare. The combined perspective of STEREO will help astronomers better understand the mechanisms for the creation and evolution of Prominences, Coronal Mass Ejections, and Solar Flares".

South_Polar_Regions-Rupes_Tenuis-ESA-PF.jpgRupes Tenuis (possible Natural Colors; credits ESA - additional color. and process. Dr Paolo C. Fienga)60 visiteESA’s Mars Express orbiter imaged the snow-laden Region of Rupes Tenuis on the Martian North Pole on 29 July 2008.
Rupes Tenuis is located at the Southern Edge of the Martian North Polar Cap, approx. 5500 Km northeast of the Tharsis Volcanic Region.
The images are at about 81° north and 297° east and have a ground resolution of approx. 41 mt/pixel. They cover an area of about 44.000 square/Km, almost as large as the Netherlands.
Nota Lunexit: a nostro avviso questa "immagine" NON E' VERA! E' un disegno. Al limite, è la trasposizione digitale di un frame RAW originale unprocessed (ma ne dubitiamo).MareKromium
