Death will come and will have your eyes.
This death that accompanies us
From morning to night, sleepless,
Deaf, like an old remorse,
Or an absurd vice.
Your eyes will be a vain word,
A silent cry, a silence.
This is how you see them every morning,
When you bend over yourself alone,
In the mirror.
O dear Hope,
That day we too will know
That you are life and you are nothing.
Death has a gaze for everyone.
Death will come and will have your eyes.
It will be like giving up a vice,
Like seeing in the mirror,
Reemerging, a dead face.
Like listening to a closed lip.
And we will descend, into the whirlpool, silent.
(Cesare Pavese, March 22, 1950)

Solar_Green-Flash.jpgA "Green Flash" from the Sun89 visiteDalla Rubrica "NASA - Picture of the Day" del giorno 4 Gennaio 2011:"Many people think it is just a myth. Others think it is true but its cause isn't yet known. Adventurers pride themselves on having seen it.
What is it?
It's a "Green Flash" from the Sun. The truth is the Green Flash does exist and its cause is well understood.
Just as the setting Sun disappears completely from view, a last glimmer appears startlingly green.
The effect is typically visible only from locations with a low, distant horizon, and lasts just a few seconds. A Green Flash is also visible for a rising Sun, but takes better timing to spot.
A dramatic Green Flash, as well as an even more rare Blue Flash, was caught in the above photograph recently observed during a Sunset visible from Teide Observatory at Tenerife, Cannary Islands, Spain.
Obviously, the Sun does not partly turn either green or blue: the effect is caused by different layers of the Earth's Atmosphere, together acting like a prism".MareKromium

Voyager_1.jpgVoyager 1, today...89 visiteLa Sonda Voyager One è stata lanciata nell'AD 1977 verso il Sistema Solare Esterno. Ormai è in viaggio da 45 anni e fino a non molto tempo fa ha continuato a inviarci dati. Poi c'è stato un problema. La NASA sapeva che il problema era da qualche parte nel sistema di articolazione e controllo dell'assetto del veicolo spaziale, o AACS (Attitude and Articulation Control Subsystem), che mantiene l'antenna della Voyager One puntata verso la Terra.
Il problema è che non è semplice fare manutenzione su un oggetto che si trova a circa 23,5 miliardi di Km dai nostri recettori.
"L'AACS aveva iniziato a inviare i dati di telemetria attraverso un computer di bordo noto per aver smesso di funzionare anni fa e il computer ha corrotto le informazioni", hanno scritto i funzionari della NASA in un aggiornamento. Una volta che i Tecnici hanno iniziato a sospettare che la Voyager One stesse utilizzando un computer guasto (nota: fra “freddo” da quelle parti…), hanno semplicemente inviato un comando in modo che il suo sistema AACS utilizzasse il computer giusto per "telefonare a casa". Era una soluzione a basso rischio, ma richiedeva molto tempo. Un segnale radio impiega più o meno 23 ore per raggiungere la Voyager One.
Ma non è finita: gli ingegneri sospettano che la Voyager One abbia iniziato a instradare la sua telemetria di stato e stato attraverso il computer morto dopo aver ricevuto un comando errato da un altro computer di bordo. Ciò suggerirebbe qualche altro problema in agguato all'interno del cervello dei computer. La NASA terrà gli occhi aperti anche su questo (si, certo, come no…).MareKromium

ZZ-ZZ-ZZ-Venus_Co_.jpgVenus, Mercury and Saturn from Brighton (Australia)88 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".

ZZ-ZZ-ZZ-ZZ-ZZ-ZZ-ZZ-ZZ-ZZ-ZZ-ZZ-ZZ-ZZ-ZZ-PIA07997-2-plusRover-A667R1.jpgVirtual Presence in Space88 visiteThis synthetic image of the Spirit MER on top of a rock called "Jibsheet" was produced using "Virtual Presence in Space" technology. Developed at NASA's Jet Propulsion Laboratory, Pasadena, Calif., this technology combines visualization and image-processing tools with Hollywood-style special effects. The image was created using a photorealistic model of the Rover and a false-color mosaic. The size of the Rover in the image is approximately correct and was based on the size of the Rover tracks in the mosaic. The mosaic was assembled from frames taken by the Pan-Cam on the Rover's 489th Martian day (May 19, 2005); see PIA07997.
Because this synthesis provides viewers with a sense of their own "virtual presence" (as if they were there themselves), such views can be useful to mission teams in planning exploration by enhancing perspective and a sense of scale.

Moon-1.jpgThe Moon over a "Red Planet"87 visiteOriginal caption:"Near its Northernmost declination, tonight's Full Moon (Dec. 15, 2005) will be a special one, arcing high in Northern Hemisphere skies. But a Full Moon won't occur on this calendar date for another 19 years, a period known as the Lunar Metonic Cycle (...)".

ZQ-MercuryTransit.jpgThe "Transit" of Mercury87 visiteDa "NASA - Picture of the Day" del 14-11-2006:" What's that dot on the Sun? If you look closely, it is almost perfectly round. The dot is the result of an unusual type of solar eclipse that occurred last week. Usually it is the Earth's Moon that eclipses the Sun. Last week, for the first time in over three years, the planet Mercury took a turn. Like the approach to New Moon before a solar eclipse, the phase of Mercury became a continually thinner crescent as the Planet progressed toward an alignment with the Sun. Eventually the phase of Mercury dropped to zero and the dark spot of Mercury crossed our parent star. The situation could technically be labeled a Mercurian Annular Eclipse with an extraordinarily large ring of fire. From above the cratered planes of the night side of Mercury, the Earth appeared in its fullest phase. Hours later, as Mercury continued in its orbit, a slight crescent phase appeared again. The next Mercurian solar eclipse will occur in 2016". MareKromium
