Moon River.jpgThe Moon over St. Lawrence River116 visiteDa "NASA - Picture of the Day" del 9 Settembre 2005:"Shortly after sunset on September 6th, sky gazers around the world were treated to a lovely crescent Moon in western skies - joined by bright planets Venus and Jupiter.
In this colorful telephoto view from near Quebec City, Canada, the Moon is nestled just above the wide St. Lawrence River. Lights on the horizon are along the river's southern shore. Also known as the evening star, Venus is at the upper left and Jupiter at the upper right, while another prominent celestial beacon, Spica, can be seen shining through the twilight below Venus.
Spica, actually a very close pair of hot blue stars some 260 LY away, is the brightest star in the constellation Virgo".Set 09, 2005

Sunrise.jpgCrepuscular Rays Over Utah61 visiteDa "NASA - Picture of the Day", del 31 Agosto 2005:"What could cause such rays of dark? Dark sky rays were caught in spectacular fashion earlier this month above Utah, USA. The cause is something surprisingly familiar: shadows. Clouds near the horizon can block sunlight from reflecting off air, making columns outward from the Sun appear unusually dark. Cloud shadows can be thought of the complement of the more commonly highlighted crepuscular rays, also visible above, where sunlight pours though cloud holes. Sometimes, on the opposite side of the sky, anticrepuscular rays can also be seen".Ago 31, 2005

Tepe_in_Malik_Shah-1937.jpgThe "Face" of Cydonia...On Earth!!!169 visiteGrazie alla collaborazione, precisa ed arguta, del nostro Lettore - il Sig. Massimo Granzo -, abbiamo scoperto che una "Faccia di Marte" esiste anche sulla Terra ed infatti...Eccola qui: siamo in Iran. La caption originale al frame che pubblichiamo ci dice "Malik Shah, close-up View of the Tepe, from an altitude of 350 mt - November 12, 1937".
Inutile dire che la somiglianza fra questa collina e la Sfinge di Cydonia è davvero incredibile...Talmente incredibile che, grazie alla pazienza ed all'attenzione del Sig. Granzo, ci viene naturale ripetere ancora un semplice concetto: non cerchiamo risposte fantastiche in pseudo-artefatti i quali, anche in ragione delle tecniche di ripresa adottate, sono per definizione ambigui; guardiamo con più attenzione i dettagli degli enormi quantitativi di materiale che abbiamo!
La Sfinge di Cydonia, a nostro parere, è solo il simbolo della Curiosità e della Fantasia Umana che si stendono oltre i confini della Terra.
La Ricerca della Vita e della Verità...E' altrove.Ago 27, 2005

ZZ-ZZ-ZZ-ZZ-ZZ-LunarGreenFlash_laveder_f.jpgA "green flash" over the Moon124 visiteDa "NASA - Picture of the Day" del 26 Agosto 2005:"July's Full Moon looks strangely darkened and distorted in this remarkable telescopic view. The image is one of a series recorded when the Moon was very near the horizon. The long sight-line through a turbulent atmosphere gives rise to the tantalizing optical effects, including the thin "mirage" shape that seems to float just above the Moon's upper edge. Also seen (more easily in the inset), along the Moon's upper edge is a noticeable green rim. Substantial atmospheric refraction produces this prism-like effect -- related to the more commonly witnessed green flash of the setting Sun. Careful inspection of the full image reveals a corresponding red rim along the lower edge, another intriguing signature of atmospheric refraction".Ago 26, 2005

ZZ-ZZ-ZZ-Venus, Mercury and Saturn.jpgVenus, Mercury and Saturn from Cerro Paranal (Chile)78 visiteDa "NASA - Picture of the Day" del 17 Agosto 2005:"Very bright planets and very large telescopes are part of this sunset view of Paranal Observatory. The observatory's four, massive 8,2 meter telescope units are situated on top of the 2.600 meter high mountain, Cerro Paranal, in the dry Atacama Desert in northern Chile. The individual unit telescopes can be used separately or in combination and are named Antu, Kueyen, Melipal and Yepun. Together they are fittingly known as the European Southern Observatory's Very Large Telescope. Of course, the very bright planets are Venus (near center), joined by Mercury (below) and Saturn (left) in late June's western evening skies".Ago 17, 2005

Inner_Worlds-jul8_westlake_f.jpgInner Worlds, in the Sunset...124 visiteDa "NASA - Picture of the Day" del 15 Luglio 2005:" Only Mars is missing from this reflective view of the major rocky bodies of the Inner Solar System. Captured on July 8th, the serene, twilight picture looks out over the Flat Tops Wilderness area from near Toponas, Colorado, USA and includes planets Mercury, Venus, Earth and Earth's large natural satellite, the Moon. The Moon is in a young crescent phase about 3° above bright planet Venus. Forest fires contribute to a layer of smoke in Earth's sky that almost hides planet Mercury, still visible very near the horizon.
Just a week earlier Venus and Mercury were joined by Saturn, forming a notable grouping in the West also enjoyed by skygazers across planet Earth".Lug 15, 2005

ZZ-ZZ-ZZ-ZZ-LunarAnalemma_richins_f.jpgMoon's analemma (New Mexico)164 visiteDa "NASA - Picture of the Day" del 13 Luglio 2005:"An analemma is an 8-like curve that is gotten when you mark the position of the Sun at the same time each day for 1 year. To imaging an analemma of the Moon it is necessary to understand that, on average, the Moon returns to the same position in the sky about 51' later each day. So, photographing the Moon 51' later on successive days, over one lunation (or Lunar month) it will trace out an analemma-like curve as the actual position of the Moon wanders compared to the average - due to the Moon's tilted and elliptical orbit. (...) Multiple exposure image required some digital manipulation, particularly to include thin crescent phases in daytime skies".Lug 13, 2005

ZZ-ZZ-The Sun over K.jpgIs this Earth?81 visiteAvevamo proposto un'immagine altrettanto enigmatica nella Sezione dedicata al Pianeta Venere, allorchè la "Stella della Sera" veniva ripresa dalla sommità di una montagna in compagnia della Luna, così generando un effetto davvero molto particolare.
Ora è la volta di un'alba, vista dal Monte Kilimanjaro. Sono stati usati filtri speciali? Forse i colori sono stati ritoccati al computer? No, su tutta la linea. Questa è una foto scattata dalla Terra, in colori reali, che riprende l'alba. Capite sempre meglio perchè la problematica dei 'Colori dello Spazio' non è accademica nè peregrina? Se, in determinate condizioni di illuminazione, ergo a diverse ore del giorno, anche la Terra può apparire un Mondo Alieno (tipo Marte o Venere) allora, date le medesime variabili, anche un Mondo Alieno potrebbe, a diverse ore del giorno, apparire come la Terra e non ci sarebbe nulla di straordinario nel dirlo e nel mostrarlo. Ma, a quanto pare, la NASA non "vede" (ed è proprio il caso di dirlo...) le cose come le vediamo noi...Lug 11, 2005

ZZ-ZZ-SunFromMaunaKea.jpgThe Sun from Mauna Kea: an alien landscape159 visiteDa "NASA - Picture of the Day" del 4 Luglio 2005:"Typically, views from Mauna Kea are up and dark. That's because the famous dormant volcano in Hawaii is arguably Earth's premier observing platform of the complex and ever changing night sky. However, this daytime view is across and bright. White snow and white clouds seem to blend together to make an alien landscape. Cinder cones from extinct volcanic outbursts dominate the foreground. Scrolling right will reveal structures visually incongruous even here: an armada of the largest optical telescopes on Earth. The observatories seen include Subaru and Keck. In the distance on the far left is Mauna Loa, Earth's largest volcano".Lug 04, 2005

ZZ-ZZ-ZZ-Venus_Co_.jpgVenus, Mercury and Saturn from Brighton (Australia)86 visiteDa "NASA - Picture of the Day" del 2 Luglio 2005:"On Tuesday, June 28th, the setting Sun flooded the horizon with a beautiful warm light in this view from the beach beside the pier at Brighton in Adelaide, South Australia. The Sun also illuminated 3 planets gathered in the Western Sky, such as Mercury, Venus and Saturn. From this perspective Mercury is at the highest point in the celestial triangle, brilliant Venus is just below, and Saturn stands farther to the left and below the close pair. Of course, the Planets only appear close together on the sky but are actually quite far apart in space. The orbits of Mercury and Venus are both interior to Earth's orbit, while gas giant Saturn lies in the outer Solar System, over 9 AU from the Sun. Late next week, Venus and Mercury will share Western Skies with the young crescent Moon".Lug 02, 2005

ZP-Mercuryandfriends.jpgMercury, Venus and Saturn in the Western Sky...Again!65 visiteDa "NASA - Picture of the Day" del 30 Giugno 2005:"Venus, Mercury, and Saturn wandered close together in western evening skies last week. On Saturday, June 25, astronomer R. Jay GaBany recorded this snapshot of their eye-catching planetary conjunction, from historic Lick Observatory on Mt. Hamilton, California, USA. The view looks toward the Pacific shortly after sunset with the lights of San Jose and the southern San Francisco Bay area in the foreground. Of course, Venus is the brightest of the trio. Mercury is nearby on the right and Saturn is below and left, closest to the horizon. Farther to the right of the planetary triangle are Pollux and Castor, twin stars of Gemini, with Regulus, bright star of the constellation Leo, at the very upper left corner of the picture. In the coming days, Venus and Mercury remain close, while Saturn continues to drop below them, toward the horizon".Giu 30, 2005
