LLQ-Itokawa-ST_2482160259_v-3.jpgRectangular Surface Feature on Itokawa? (extra-detail mgnf)58 visiteAllora, fermiamoci ai fatti: il "rettangolo" esiste (e si vede bene) ed alla sua base c'è effettivamente qualcosa che non può essere altro che una apertura.
Questo rilievo - che solo un occhio attento al dettaglio poteva individuare - rientra, a nostro parere, nella Classe delle Singolarità Superficiali.
E' un rilievo affascinante, suggestivo, decisamente curioso: certo. Ma quali elementi abbiamo per poter anche solo supporre una sua origine NON naturale?
Nessuno.
L'intero Asteroide Itokawa è un campionario di Singolarità, le quali vanno dalla mancanza di crateri alla presenza, su un buon 75% della sua superficie, di una sorta di "squamatura rocciosa" (si tratta di mini-boulders a forma appuntita ed inclinati - leggermente - rispetto al piano dell'asteroide).
Itokawa (al pari di Phobos, o di 1-Ceres, o di 433-Eros, o al pari delle "unexplainable surface features" di Marte, di Giapeto, di Callisto ed Europa e così via), è una Meraviglia della Natura: è unico, è lontano, è affascinante e, per noi, è largamente inesplicabile.
Parlare di "intervento intelligente" (come sinonimo di "NON naturale") allorchè si analizzano rilievi come questo (o come quelli relativi agli altri Corpi Celesti sopra menzionati), vuol dire - a nostro parere - NEGARE la Capacità Creativa della Natura e, di fatto, significa rifiutarsi di vedere l'Universo per quello che è davvero: una Meravigliosa Opera la quale, per il suo 99,99%, era, è e - probabilmente - rimarrà uno splendido enigma per gli Uomini.
Un enigma che dovrebbe invogliarci a studiare di più e meglio, a capire di più e meglio e ad essere un pochino più umili e consapevoli dei nostri limiti e della attuale nostra incapacità di razionalizzare tutto quello che vediamo e quindi di sussumere l'Ignoto all'interno di Classi di Conoscenza ancora largamente e profondamente imperfette.
Un profondo ringraziamento all'Amico e Collega, Dr Gianluigi Barca, per l'eccezionale "occhio" e per la splendida provocazione che ha lanciato: provocazione che ci ha offerto un eccellente spunto per esprimere un pensiero che, in tanti ormai, avevamo da tempo voglia di tradurre in parole.MareKromiumNov 05, 2007

Comets-Comet_Holmes-UW.jpgComet 17-P-Holmes is getting Bigger!60 visiteCaption NASA, da "NASA - Picture of the Day", del 5 Novembre 2007:"Comet Holmes continues to be an impressive sight to the unaided eye. The comet has diminished in brightness only slightly, and now clearly appears to have a larger angular extent than stars and planets.
Astrophotographers have also noted a distinctly green appearance to the comet's coma over the past week.
Pictured above over Spain in 3 digitally combined exposures, Comet 17P/Holmes now clearly sports a tail. The blue ion tail is created by the solar wind impacting ions in the coma of Comet Holmes and pushing them away from the Sun. Comet Holmes underwent an unexpected and dramatic increase in brightness starting only two weeks ago. The detail visible in Comet Holmes' tail indicates that the explosion of dust and gas that created this dramatic brightness increase is in an ongoing and complex event.
Comet Holmes will move only slightly on the sky over the next month (such as December 2007)".MareKromiumNov 05, 2007

Comets-Comet_Holmes-TW-P17HolmesWeb3_goldman.jpgComet 17-P-Holmes and its Golden Coma54 visiteCaption NASA, da "NASA - Picture of the Day", del 3 Novembre 2007:"Surprising Comet Holmes remains easily visible as a round, fuzzy cloud in the Northern constellation Perseus. Skywatchers with telescopes, binoculars, or those that just decide to look up can enjoy the Solar System's latest prodigy as it glides about 150 MKM from Earth, beyond the orbit of Mars.
Still expanding, Holmes now appears to be about 1/3 the size of the Full Moon, and many observers report a yellowish tint to the dusty coma. A golden color does dominate this telescopic view recorded on November 1, showing variations across the coma's bright central region.
But where's the comet's tail? Like any good comet, Holmes' tail would tend to point away from the Sun. That direction is nearly along our line-of-sight behind the comet, making its tail very difficult to see". MareKromiumNov 03, 2007

Comets-Comet_Holmes-UV.gifComet 17-P-Holmes55 visiteCaption NASA, da "NASA - Picture of the Day" del 30 Ottobre 2007:"Go outside tonight and see Comet Holmes.
No binoculars or telescopes are needed -- just curiosity and a sky map.
Last week, Comet 17P/Holmes underwent an unusual outburst that vaulted it unexpectedly from obscurity into one of the brightest comets in recent years.
Sky enthusiasts from the Northern Hemisphere have been following the comet's progress closely. Pictured above Quebec, Canada, the coma of Comet Holmes has been noticeably expanding over the past few days. In the above picture, an image of Jupiter has been placed artificially nearby to allow for a comparison of angular sizes.
Jupiter has been scaled to the size it would appear at the current location of Comet Holmes. How Comet Holmes will further evolve is unknown, with one possibility being that the expanding gas cloud that started from its recent outburst will slowly disperse and fade".MareKromiumOtt 30, 2007

Comets-Comet_Holmes-TView.jpgTelescopic View of the Comet Holmes56 visiteCaption NASA, da "NASA - Picture of the Day" del 29 Ottobre 2007:"What's happened to Comet Holmes? A normally docile comet discovered over 100 years ago, Comet 17P/Holmes suddenly became nearly one million times brighter last week, possibly over just a few hours. In astronomical terms, the comet brightened from magnitude 17, only visible through a good telescope, to magnitude 3, becoming visible with the unaided eye. Comet Holmes had already passed its closest to the Sun in 2007 May outside the orbit of Mars and was heading back out near Jupiter's orbit when the outburst occurred. The comet's sudden brightening is likely due to some sort of sunlight-reflecting outgassing event, possibly related to ice melting over a gas-filled cavern, or possibly even a partial breakup of the comet's nucleus. Pictured above through a small telescope, Comet Holmes appeared as a fuzzy yellow spot, significantly larger in angular size than Earth-atmosphere blurred distant stars. Although Comet Holmes' orbit will place it in northern hemisphere skies for the next two years, whether it will best be viewed through a telescope or sunglasses remains unknown".MareKromiumOtt 29, 2007
