SOU-SOL024-2.jpgSunset (2) - Sol 2474 visiteThis image of the Martian sunset from Sol 24 shows much more color variation than had previously been seen. The blue color near the Sun is not caused by clouds of water ice, but by the Martian dust itself. The dust in the atmosphere absorbs blue light, giving the sky its red color, but it also scatters some of the blue light into the area just around the Sun because of its size. The blue color only becomes apparent near Sunrise and Sunset, when the light has to pass through the largest amount of dust.

APOLLO 13 AS 13-62-8905 GOLDEN ANOMALY3.jpgAS 13-62-8905 - The "Golden Anomaly" - detail mgnf 2692 visiteQualche Lettore del bell'articolo di Fabio Italiano (vedi "Strani Compagni di Viaggio" su SpazioUFO.com - http://www.spazioufo.com/apollo13.asp) suggerisce una possibile "natura biologica" della Golden Anomaly. Noi, pur rispettando al massimo le opinioni di tutti, ci permettiamo un piccolo e modesto suggerimento: attenzione a "suggerire" ipotesi fortemente esotiche (come questa) allorchè gli elementi di supporto sono pari a "0". In questa maniera - usata da parecchi personaggi molto vicini al CUN e ad altre Istituzioni (chiamiamole così) "Storiche" per lo studio del fenomeno UFO - ma solo per esigenze di "cassetta" e di "visibilità"), si rischia di banalizzare tutta la Materia (serissima) e di passare - se va bene - per visionari.
E' evidente che, in certi casi, "TUTTO" può essere, data anche l'assenza di elementi certi (anzi: data l'assenza di elementi tout-court!), ma è pure evidente che gli Studiosi Seri del fenomeno UFO (che sono tanti - e, scusateci, NON includiamo il CUN in questa Categoria), danno "fastidio" e quindi, non appena nasce l'occasione, si cerca subito di farli passare per "personaggi strani" (e cioè, spesso, per "stravaganti", mitomani o, in certi casi, addirittura per persone mentalmente disturbate).
A volte, purtroppo, questo accade perchè si cerca di dare delle risposte anche quando dare risposte è, semplicemente, impossibile.
Come in questo caso.
Il mio suggerimento? In casi del genere parliamo di UFO (o di OVNI) e basta. Restiamo pragmatici (anche se la voglia di ipotizzare è forte): solo così, forse, si riuscirà - un giorno - a far uscire l'Ufologia dalla gabbia dell'esoterismo e delle discipline ad esso connesse e collegate ed a farla entrare a pieno titolo nel campo delle Scienze.

Sun Pillars.jpgLight Pillars' Parade77 visiteDa "NASA - Picture of the Day" del 5 Marzo 2006:"How can an aurora appear so near the ground? Pictured above are not aurora but nearby light pillars, a local phenomenon that can appear as a distant one. In most places on Earth, a lucky viewer can see a Sun-pillar, a column of light appearing to extend up from the Sun caused by flat fluttering ice-crystals reflecting sunlight from the upper atmosphere. Usually these ice ice crystals evaporate before reaching the ground. During freezing temperatures, however, flat fluttering ice crystals may form near the ground in a form of light snow, sometimes known as a crystal fog. These ice crystals may then reflect ground lights in columns not unlike a Sun-pillar. In the above picture, the colorful lights causing the light pillars surround a ice-skating ring in Fairbanks, Alaska".

RS-Ophiuci-1.jpgNova RS-Ophiuci61 visite"...Ormai gli spazi in cui la volontà individuale può ancora esercitarsi sono così rari e angusti che il nostro buon Italiano Medio non li affida al suo padrone di turno, ma ne pretende la determinazione: almeno sul pollo decido io! esclama il nostro Signor X medio.
Bombardato da puro terrorismo mediatico, vessato da leggi e decreti come neppure in epoca carolingia, umiliato da una politica fatta da una minoranza di onnipotenti e intoccabili, straziato da un carovita che farebbe urlare di dolore un mugik, istupidito da una sistematica demolizione della libera cultura, il povero Signor X non è più in grado di progettare il suo futuro, non sa vedere oltre la fine del mese, non può più sperare in un felice avvenire per i suoi figli.
Schiavo sotto i Romani, servo della gleba nel Medioevo, operaio sottopagato nella Rivoluzione Industriale, carne da cannone in due Guerre Mondiali, burattino decerebrato sotto la dittatura fascista, carne da radiazione nella Guerra Fredda, carne da tv adesso, il povero Signor X si guarda attorno e, a fatica, esce dal torpore muto in cui lo tiene immerso, come in formalina, il padrone di turno…Esce dal torpore e comincia a temere che ci sia qualcosa che forse non va…
E non compra più il pollo che prima mangiava di gusto..."

Telesto-PIA07702.jpgTelesto62 visiteThe Cassini spacecraft passed within a cosmic stone's throw of Telesto in October, 2005 capturing this shot of the tiny Trojan moon. Telesto (24 Km, or 15 miles across) appears to be mantled in fine, icy material, although a few craters and some outcrops and/or large boulders are visible. Its smooth surface does not appear to retain the record of intense cratering that most of Saturn's other moons possess.
The image was taken in polarized green light with the Cassini spacecraft narrow-angle camera on Oct. 11, 2005, at a distance of approx. 14.500 Km (9.000 miles) from Telesto. The image scale is 86 mt (about 283 feet) per pixel.

Albategnius-2.jpgAlbategnius Crater (2)130 visiteAlbategnius (Al-Battani, Muhammad ibn Jabir) (approx. 850-929)
--------------------------------------------------------------------------------
An Iraqi prince, born in Batan, Mesopotamia (Iraq), who was the leading Astronomer and Mathematician of his time. He drew up improved tables of the Sun and Moon, measured the eccentricity of Earth’s orbit and the inclination of Earth’s Equator to its orbital plane. He was capable of making an extremely accurate measurement of the length of the Earth year - which was also used in the Gregorian reform of the Julian Calendar. His observations at Rakku, made over (probably) a 40-year period, were summarized in his work "Movements of the Stars" (first published in Europe in 1537).
Thanks to his contribution, Johannes Hevelius (1611-1687) was able to theorize and discover the secular variation in the Moon’s motion.

NGC-1999-00.jpgNGC 1999 - The "X" Nebula in Orion60 visite"Zéfiro già, di be' fioretti adorno,
avea de' monti tolta ogni pruina,
avea fatto al suo nido già ritorno
la stanca rondinella peregrina;
risonava la selva intorno intorno
soavemente all'òra mattutina:
e la ingegnosa pecchia al primo albore
giva predando ora uno or altro fiore..."

SOL731-PIA06102.jpgMartian "Corals" (approx. true colors) - Sol 73163 visiteThe change in textures and the location of the basalts may be signs that Spirit is driving along the edge of a lava flow. This lava may be the same as the basalt blanketing the plains of Spirit's Landing Site, or it may be different. The large size and frothy nature of the boulders around Lorre Ridge might indicate that eruptions once took place at the edge of the lava flow, where the lava interacted with the rocks of the basin floor. Scientists hope to learn more as Spirit continues to investigate these rocks.
As Earth approaches the Chinese New Year (The Year of the Dog), the Athena Science Team decided to use nicknames representing Chinese culture and geography to identify rocks and features investigated by Spirit during the Chinese New Year celebration period. In ancient Chinese myth, FuYi was the first great emperor and lived in the East. He explained the theory of "Yin" and "Yang" to his people, invented the net to catch fish, was the first to use fire to cook food, and invented a musical instrument known as the "Se" to accompany his peoples' songs and dances. Other rocks and features are being informally named for Chinese gods, warriors, inventors, and scientists, as well as rivers, lakes, and mountains.
Spirit took this image on the rover's Martian day, or sol, 731 (Jan. 23, 2006). This is an approximate true color rendering combining images taken with the Pancam's 750-nanometer, 530-nanometer and 430-nanometer filters.

SOL731-PIA06101.jpgMartian "Corals" (false colors) - Sol 73164 visiteIn recent weeks, as NASA's MER Spirit has driven through the basin south of Husband Hill, it has been traversing mainly sand and dune deposits. This week, though, Spirit has been maneuvering along the edge of an arc-shaped feature called Lorre Ridge and has encountered some spectacular examples of basaltic rocks with striking textures. This PanCam image shows a group of boulders informally named "FuYi". These basaltic rocks were formed by volcanic processes and may be a primary constituent of Lorre Ridge and other interesting landforms in the basin.
Spirit first encountered basalts at its landing site 2 years ago, on a vast plain covered with solidified lava that appeared to have flowed across Gusev Crater. Later, basaltic rocks became rare as Spirit climbed Husband Hill. The basaltic rocks that Spirit is now seeing are interesting because they exhibit many small holes or vesicles, similar to some kinds of volcanic rocks on Earth. Vesicular rocks form when gas bubbles are trapped in lava flows and the rock solidifies around the bubbles. When the gas escapes, it leaves holes in the rock. The quantity of gas bubbles in rocks on Husband Hill varies considerably; some rocks have none and some, such as several here at FuYi, are downright frothy.

ZZ-ZZ-ZZ-FM-TLP.gifTLP or illuminated "peaks" (again)?140 visiteObserver Joshua Try located in Whangarei, New Zealand reported that on 25-09-2001 at 8:30 U.T. he observed two possible L.T.Ps. on the edge of the terminator near the crater Archimedes. They appeared to be 2 bright points of light about the size of Mount Piton. They seem to form a triangle with Mount Piton. He observed them for 2 hours and they were still visible when he ended his observing session.
I had the opportunity to conduct some video tapping of the Moon on 22 January 2002 at 00 hr 18 min U.T. and was able to capture the Moon under similar lighting conditions. The image was taken with SCT C8 using 25mm eyepiece in projections. This image was taken when the Moon was 8.4 days old and the colongitude was 8.92. It may be that since the locations are very close that what Joshua saw was the tops of the mountain peaks just catching the sunlight. My image which is one lunar day later shows the mountains fully illuminated. I have had several reports in the past years that have reported these features as possible L.T.P. It can be very impressive and striking when one first sees these feature just catching the sunlight. It is my opinion that what the observer witness was peaks of these two mountains deep past the sunrise terminator.
