X-Moon.jpgX-Moon!336 visiteDa "NASA - Picture of the Day" del giorno 11 Marzo 2009:"The striking "X" near the center of this lunarscape is easily visible in binoculars or a small telescope. Yet, not too many have seen it. The catch is, this Lunar "X" is only apparent during a 4 hour period just before the Moon's first quarter phase.
At the Terminator, or shadow line between lunar day and night, the X illusion is produced by a configuration of the craters Blanchinus, La Caille and Purbach.
Near the Moon's first quarter phase, an astronaut standing close to the craters' position would see the slowly rising Sun very near the horizon. Temporarily, the crater walls would be in sunlight while the crater floors were still in darkness.
Seen from planet Earth, contrasting sections of bright walls against the dark floors by chance look remarkably like an X. This sharp image of the Lunar "X" was captured at approx. 11:59 UT on March 3, 2009. The Moon's first quarter phase was at at 7:46 UT on March 4, AD 2009".MareKromium

ZZ-ZZ-ZZ-ZZ-ZZ-Lunar South Pole.jpgNo "Lunar Ice" at the South Pole...66 visite"...a new radar survey of the Moon’s Southern Pole has cast doubt on the hope that there might be accessible deposits of water ice in permanently dark craters. This new survey, performed with the Arecibo Observatory in Puerto Rico, found elevated Hydrogen levels in regions of bright sunlight - not just inside the shadowed walls of craters. It seems that scattered rocks associated with impact craters have given previous instruments a false reading...".

ZZ-ZZ-ZZ-FP-Clem-BrightAristarchus.gifAristarchus: the TLPs "Hottest Spot" (1)151 visiteA mosaic of more than 250 images showing the complex and diverse Aristarchus Region of the Moon in approximately "natural" colors (blue = 415 nanometers, green = 750 nanometers, red = 950 nanometers). The plateau is an uplifted block of complex, highland terrain, partly flooded by later mare basalt lavas. Dark, pyroclastic glasses partly cover the uplifted terrain. The crater Aristarchus (47 Km in diameter) has formed in the South-Western corner of the Plateau, excavating both highlands and mare rocks."

ZZ-ZZ-ZZ-FN-Earthshine.gifCoronal Mass Ejection and Earthsine112 visiteThis photograph was taken by Devgun Chander of Sohna, Haryana, of India. It shows a striking clarity to the earthshine region of the Moon. When I first look at the photograph I was impressed that Aristarchus was standing out so bright even though it very close to the sunset terminator. I sent the photograph to Dr. Anthony Cook the senior recorder for the L.T.P. sections of BAA and ALPO. He sent me the measured brightness of specific lunar formations and of the Lunar Maria.
(...) The Maria across the face of the Moon is uniformly bright except for the formations Mare Humorum, Mare Frigoris and Maria located near Aristarchus. Dr. Anthony Cook believes they are brighter due to the glare from the nearby sunset terminator. (...) The fact that we had a significant coronal mass ejections into space or CME take place on November 8-9,2004 causing aurora reports all over the World. If Solar Excitation is a factor for the extreme brightness of the Earthshine this would be the event to cause it.

M-Lobachewsky Anomaly.gifThe Lobachevsky Anomaly, from Clementine (1)187 visiteLa struttura verticale che, nel frame AS 16-121-19407, pareva sovrastare questo crepaccio netto e profondo, non si riesce più a vedere.
Forse - anzi: certamente - si trattava di un photographic artifact (determinato dalla compressione del frame): siamo comunque in attesa di entrare in possesso del frame originale non compresso per verificare meglio.
Tutto ciò che si vede in questo frame è un "seepage" (una "colata" scura) che si diparte dal bordo di un dosso.
NON E', come Hoagland e qualche altro suo seguace sostengono, una sorta di "apertura", decisamente anomala nei contorni e nelle caratteristiche esteriori, che pare "affondare" nella superficie della Luna e condurre nelle profondità del nostro Satellite (praticamente l'imbocco di una miniera).
NON è quello che sembra, insomma, e basta guardare con attenzione e cautela per capirlo.

The Far Side Of The Moon - Clem.jpgThe Limb of Gagarin - Far Side206 visiteCi è sempre stato difficile reperire immagini del "lato oscuro" (o "far side" o "dark side") della Luna.
Questa è una delle poche di cui siamo venuti in possesso e che Vi proponiamo: niente di eccezionale, purtroppo, ma si tratta comunque di un'immagine interessante e che riguarda il "volto nascosto" (e, dunque, più affascinante...) del nostro Satellite.

Clavius GIF.gifClavius...on line!164 visiteUno spettacolare lavoro (davvero!) dell'Astronomo Robert Spellman (www.angelfire.com) il quale, nel tentativo di fissare su pellicola qualche TLP, ci ha regalato delle immagini davvero superbe di alcuni grandi (e famosi) Crateri Lunari e, come in questo caso, dei minifilmati GIF che ci fanno provare l'ebbrezza di essere "in diretta con la Luna", anche se siamo seduti davanti al nostro pc.
Un ottimo lavoro: i TLP "on line"...Verranno (almeno questo è quanto gli e ci auguriamo!).

ZZ-ZZ-MoonMirEarth_STS91_big.jpgEarth - Moon - MIR from STS 91176 visiteDa "NASA - Picture of the Day" del 30 Aprile 2005:"While orbiting the planet during their June 1998 mission, the crew of the Space Shuttle Discovery photographed this view of two moons of Earth. Thick storm clouds are visible in the lovely Blue Planet's nurturing atmosphere and, what was then Earth's largest artificial moon, the spindly Russian Mir Space Station can be seen above the Planet's limb. The bright spot to the right of Mir is Earth's very large natural satellite, the Moon. The Mir orbited planet Earth once every 90 minutes about 200 miles above the planet's surface or about 4.000 miles from Earth's center. The Moon orbits once every 28 days at a distance of about 250.000 miles from the center of the Earth".
