Oklo_on_Earth-_Oklo_15.jpgOklo 15210 visiteCaption NASA, da "NASA - Picture of the Day" del giorno 12 Settembre 2010:"The remnants of nuclear reactors nearly two billion years old were found in the 1970s in Africa.
These reactors are thought to have occurred naturally. No Natural Reactors exist today (nota Lunexit: on Earth!), as the relative density of Fissile Uranium has now decayed below that needed for a sustainable reaction.
Pictured above is Fossil Reactor 15, located in Oklo, Gabon. Uranium Oxide remains are visible as the yellowish rock. Oklo by-products are being used today to probe the stability of the Fundamental Constants over Cosmological Time and Distance Scales and to develop more effective means for disposing of human-manufactured nuclear waste".

APOLLO_15_-_AS_15-P-9625-06.jpgAS 15-P-9625 (6) - The buried "Spacecraft" and the "Lunar Eel" (annotated frame)632 visiteUn'ultima annotazione suggeritaci - in un certo senso - dal nostro Amico e Socio Fabio Italiano (OldGrey) con le sue ultime (e comunque belle) elaborazioni: il rilievo denominato "astronave" (il quale altro non è che una delle porzioni illuminate del complesso collinare al quale esso accede) sembra acquisire una dignità autonoma - e quindi configurarsi come "struttura (colonnare o simil-colonnare) a sè stante" - solo perchè (a nostro parere, ovviamente) è stato operato uno stretch, in termini di contrasto (contrast enhancement) fra corpi in luce (i quali ora ci appaiono di color bianco/grigio chiaro) e corpi in ombra (che invece ci appaiono di color nero/grigio scuro), decisamente eccessivo.
Questo significa che basta ridurre il contrasto per vedere (BENE!) che la nostra "astronave" è solamente una - modesta, per giunta - porzione della collina che sorge al centro dell'immagine e la cui parete (in ombra) ci ha a lungo tratti in inganno.
Insomma: elaborare le immagini, come detto, a volte aiuta ed altre volte...inganna.
La variabile iniziale (e spesso decisiva, in questo campo) è data da colui che opera sul frame originale ed è per questo che la NASA (e l'ESA), se vuole/vogliono, può/possono ingannare tutti.
Ed è questo uno dei concetti-cardine del nostro Lavoro; un concetto che, tra mille difficoltà (anche dovute alla enorme mancanza di conoscenza esistente in materia), stiamo cercando di rendere chiaro a tutti.
E come sempre...Pensateci sopra!MareKromium

EROS-nea_0144528838_mos.jpgAsteroid 433-Eros from NEAR (9) - Original and HR100 visiteDettaglio del rilievo che, anche senza ingrandimento, già ci appare ben visibile nel frame che precede. Si tratta, con ogni probabilità, della parte superiore di una collinetta (anche se - forse - sarebbe meglio parlare di un semplice "outcrop", date le modeste dimensioni dell'Asteroide).
La NASA, purtroppo, non ci è stata di aiuto quando abbiamo chiesto delle delucidazioni al riguardo.

Mimas-N00055623.jpgMimas (2)61 visiteCaption originale:"N00055623.jpg was taken on March 21, 2006 and received on Earth March 22, 2006. The camera was pointing toward Mimas that, at the time, was approximately 190.524 Km away.
The image was taken using the CL1 and CL2 filters".

Juventae_Chasma_3D-1.JPGJuventae Chasma (High-Def-3D; credits: ESA)96 visiteSpettacolare: un 3D assolutamente straordinario.
Original caption:"These images, taken by the HR Stereo Camera (HRSC) on board ESA’s Mars Express spacecraft, show the depression of Juventae Chasma, cut into the plains of Lunae Planum on Mars.
The HRSC obtained these images during orbit 243 with a ground resolution of approximately 23,4 mt per pixel. The scenes show the region of Lunae Planum, at approximately 5° South and 297° East.
The depression of Juventae Chasma, located North of Valles Marineris, cuts more than 5000 mt into the plains of Lunae Planum. The floor of Juventae Chasma is partly covered by dunes.
In the valley, to the North-East, there is a mountain composed of bright, layered material. This mountain is approximately 2500 mt high, it has a length of 59 Km and a width of up to 23 Km. The OMEGA spectrometer on board Mars Express discovered sulphate on the surface of Mars and confirmed that this mountain is indeed composed of sulphate deposits".

Mimas&Titan-PIA07666.jpgBig Brother, Little Brother...56 visiteOriginal caption:"Titan, the Saturn's largest moon and Mimas - in the foreground - are seen together in this view from Cassini.
Titan's gravity is weaker than Earth's, so the moon's atmosphere is quite extended - a "quality" that is very well hinted at in this view.
Part of Mimas' dark side is illuminated by reflected light from nearby Saturn.
The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Dec. 3, 2005, at a distance of approx. 3,6 MKM (about 2,2 MMs) from Titan and 2,5 MKM (1,6 MMs) from Mimas.
Both moons are seen at a phase angle of 110°.
The image scale is 22 Km (roughly 14 miles) per pixel on Titan and 15 Km (about 9 miles) per pixel on Mimas".

Dione-PIA07745-1.jpgDione's horizon - HD (1)56 visiteOriginal caption:"As it departed its encounter with Saturn's moon Dione, Cassini sailed above an unreal landscape blasted by impacts. The rising Sun throws craters into sharp contrast and reveals steep crater walls.
At the far right, a medium-sized crater is bisected by a fracture, revealing a cross section of the impact site.
The seven clear-filter images in this mosaic were taken with the Cassini spacecraft narrow-angle camera on Oct. 11, 2005, at distances ranging from of 21.650 to 25.580 Km (about 13.450 to 15.890 miles) from Dione and at a Sun-Dione-spacecraft, or phase, angle of 154°. Resolution in the original images ranges from 126 to 154 mt (about 413 to 505 feet) per pixel. The images have been re-sized to have an image scale of about 100 mt (330 feet) per pixel. North on Dione is 140° to the left".
