ALPHA CENTAURI.jpgAlpha Centauri - European Southern Obs.167 visite"...Ho visto una Stella sorgere, dalle profondità del Mare, ed ergersi, luminosa, sino alla sommità del Cielo. Una Nuova Stella che splende su di noi, che ci guarda, ci osserva, ci scruta. Una Nuova Stella che illuminerà nuovi Percorsi, Pensieri, Passioni, Opere ed Omissioni.
Ho visto una Stella sorgere, dalle profondità del Mare, e perdersi, nei crepacci dell'Infinito. Grande la Luce emessa e l'Energia, breve il Tempo concessole.
Povera Stella..."

Aldebaran & Betelgeuse.jpgBetelgeuse, Aldebaran and a shooting star429 visite"Dio degli Eserciti,
Vogliamo tornare a casa...
Dio degli Eserciti,
Abbiamo corpi da abbracciare,
Cose da fare ed occhi
Da non dimenticare...
Dio degli Eserciti,
Abbiamo ossa stanche, da riposare,
Anche se il cuore batte,
Al ritmo di un tamburo...
Dio degli Eserciti:
Ascolta il nostro Grande Silenzio,
Pieno di carni straziate e di metallo rovente...
Dio degli Eserciti,
La notte è chiara, come il giorno,
Ma lunghe ombre ci inseguono,
E il giorno è buio, e fa paura...
Dio degli Eserciti,
Vogliamo tornare a casa:
Tu che lo puoi, se vuoi, lo fai...
(Daniele Di Tonno - "Poesie")

Comets-Garrad-PIA12985.jpgComet Garradd54 visiteThis image from the WISE mission was taken on January 2nd, 2010, during the check-out phase, before the start of the WISE survey. It is a mosaic of 3 individual WISE frames spanning an area on the sky about 7 times the size of the full Moon in portions of the constellations Bootes and Canes Venatici.
In the lower right portion of the image there is a streak of orange light. This is most likely a human-made satellite, orbiting Earth at a higher altitude than the WISE telescope, which is at 523 km above the surface. WISE sees many of these as it scans the sky.
Just above the satellite in the image is Comet C/2008 Q3 (Garradd). Comets are balls of dust and ice left over from the formation of the Solar System. As a comet approaches the Sun it is heated and releases gas and dust from its surface that is blown back by the solar wind into a long, spectacular tail. This comet was discovered in August 2008 by Gordon Garradd of the Siding Spring Observatory in Australia. This comet probably comes from the Oort Cloud, a vast collection of remnants from the formation of the Solar System thought to surround it. At the time the comet was observed by WISE, in the constellation Bootes, it was a distance of 419 million kilometers (2.789 Astronomical Units, AU) from Earth. But we are just catching it while it is near the Sun. The orbit calculated for Comet C/2008 Q3 (Garradd) is inclined to the plane of the Solar System by nearly 140 degrees and takes it very far from the Sun (trillions of kilometers). It made its closest approach to the Sun in June of 2009 at a distance of 1.8 AU (270 million km), just outside the orbit of Mars. If it comes back near the Sun at all, it won't be for hundreds of thousands of years.
In the upper left of the image is the impressive globular cluster Messier 3 (M3). M3 was discovered in the constellation Canes Venatici by famous French Astronomer, Charles Messier in 1764, and first seen to be made of stars around 1784 by the British astronomer who discovered infrared light, William Herschel. Globular clusters are huge globs of stars (hence the name) that are found orbiting in the outer reaches of most galaxies. They are thought to form around the same time that a galaxy forms. The Milky Way has over 200 known globular clusters. M3 is one of the largest and brightest globular clusters around the Milky Way. It is just barely visible to the naked eye from a dark location. M3 is made of about half a million stars, thought to be about 8 billion years old. It is about 150 light-years across (1 light-year is equal to 9.46 trillion km) and located some 34,000 light-years from Earth.
WISE sees invisible infrared light, and the colors here are mapped to 3 of the 4 wavelength bands observed by WISE. Blue represents light with a wavelength of 3.4 microns, cyan maps to 4.6 microns and red is lightat 12 microns (a micron is 1 millionth of a meter, and visible light runs from 0.4-0.7 microns). The light from relatively hot objects, like stars in M3, is seen in blue and cyan. Red color represents cooler things, like dust from the comet and its tail. When this image was taken the WISE team was still calibrating the rate of the scan mirror with the motion of the WISE telescope. The rate was not yet perfected and careful examination of this image reveals some stars that are a little smeared and not exactly aligned in the blue/cyan with the red.

HR 4796 a.jpgHR 4796a63 visite"...J'ai la chance d'avoir deux Pays,
Je suis un peu d'içi, un peu de là-bas...
Pourtant, j'ai toujours une valise prete
Dans mon ame...
Hésitante, entre les deux, son coeur balance...
Ballotté entre mes deux reves,
Je deviens le jouet fragile des flots...
J'ai de la chance. J'ai deux Pays...
Et une valise qui ne se posera, peut-etre, jamais..."

M 42-PIA08656.jpgOrion's "Sword"53 visiteThis image composite outlines the region near Orion's sword that was surveyed by NASA's Spitzer Space Telescope (white box). The view on the left (figure 1) is from a visible-light telescope, and the view on the right (figure 2) shows infrared light captured by a previous infrared mission, the Infrared Astronomical Satellite.
The Orion nebula, our closest massive star-making factory, is the brightest spot near the hunter's sword. On a dark night, it can appear to the naked eye as a fuzzy star, and it looks like a ghostly blob through a pair of binoculars. The Orion constellation is one of the most prominent winter constellations, and can be seen from all northern latitudes starting in the fall.
Spitzer used its infrared eyes to probe the dusty clouds of a region called Orion cloud A. outlined here in the hockey stick-shaped box (see PIA08655). This giant cloud stretches almost a quarter of the length of the constellation, an area equivalent to 18 full moons. The small box within the hockey stick shows the location of another image released by Spitzer (see PIA08653), which mainly features the Orion nebula itself.
The bright spot that shows up in the infrared view in the area of Orion's belt is known as Orion cloud B. Together, Orion clouds A and B make up the Orion cloud complex. In a survey of this entire complex, Spitzer unearthed 2,300 stars circled by disks of planet-forming dust and 200 stellar embryos too young to have developed disks.
The Infrared Astronomical Satellite was a joint effort between NASA, the Science and Engineering Research Council, United Kingdom and the Netherlands Agency for Aerospace Programmes, the Netherlands. Spitzer has extended the legacy of the satellite by providing much better resolution and sensitivity.

Milky_Way.jpgThe Milky Way: a picture or a drawing?241 visiteThis panorama view of the sky is really a drawing. It was made in the 1940s under the supervision of astronomer Knut Lundmark at the Lund Observatory in Sweden. To create the picture, draftsmen used a mathematical distortion to map the entire sky onto an oval shaped image with the plane of our Milky Way Galaxy along the center and the north galactic pole at the top. 7.000 individual stars are shown as white dots, size indicating brightness. The "Milky Way" clouds, actually the combined light of dim, unresolved stars in the densely populated galactic plane, are accurately painted on, interrupted by dramatic dark dust lanes. The overall effect is photographic in quality and represents the visible sky. Can you identify any familiar landmarks or constellations? For starters, Orion is at the right edge of the picture, just below the galactic plane and the Large and Small Magellanic Clouds are visible as fuzzy patches in the lower right quadrant.
