M-100-2.jpgCepheid in M 100120 visite"...Ricordo la Luna, si...Dalla finestrella di sinistra del Modulo, lo ricordo bene, un forte contrasto di luce e di oscurità. Luce bianca.
E poi la sensazione di - come dire? - movimento. Movimento esterno.
Un rapido alternarsi di ombre e di luci, ma potrebbe essere un'illusione, poichè sto per addormentarmi...L'ossigeno che respiro e che mi arriva sulla bocca, quasi costantemente, è freddo.
E' freddo ed ha un sapore a tratti metallico e, in altri momenti, come di gomma. E' l'aria che respiro che ha questo "sapore".
Sono disteso, cerco di addormentarmi, ma non riesco a distogliere lo sguardo da tutti quei movimenti che riesco ad intuire, guardando ombre e luci che si inseguono...
Ma sono sulla Luna: fuori non c'è nessuno. Non ci può essere nessuno e dunque è evidente che sto già sognando...".

Messier_074-PIA13376.jpgM 74 - Spiral Galaxy, the Asteroid 3540 Protesilaos and an unsual resemblance...119 visiteCaption NASA:"It's a bird! It's a plane! Nope, it's an Asteroid tracking its way across the sky with a beautiful Spiral Galaxy in the background. In the center of this new mosaic image captured by NASA's Wide-field Infrared Survey Explorer (WISE) is the galaxy Messier 74, with its spiral arms seen face-on. The bright reddish object moving across the lower right part of the image is the much closer asteroid 3540 Protesilaos, seen at different points in its orbit around the Sun. WISE observed and detected this previously known Asteroid a total of ten times, although only a few of those frames were used in this mosaic.
Also known as NGC 628, the Messier 74 Galaxy is between 24,5 and 36 Million Light-Years away, and has a diameter of about 100.000 LY.
It is suspected to have a Black Hole at its center, with a mass equal to 10.000 Suns. It is one of only a handful of known Black Holes with masses intermediate between the relatively smaller ones that form from collapsing stars and the supermassive Black Holes millions of times more massive than the Sun, which are more typically found at the centers of Galaxies.
Although it is called a Messier Object, Messier 74 was actually discovered by Pierre Mechain in 1780, who then told his friend Charles Messier about it. As one of the dimmest of all Messier objects, this Galaxy is a challenge for amateur astronomers to see in Visible Light, but the WISE cameras captured it clearly in InfraRed Light.
The colors used in this image represent different wavelengths of IR Radiation. Blue and cyan represent light at 3,4 and 4,6 microns, respectively. These colors show both nearby stars inside the Milky Way Galaxy and the combined light of billions of stars that make up Messier 74. Green and red represent light from 12 and 22 microns, respectively. These colors show light from cooler objects and material. Dust in star-forming regions in Messier 74 traces its spiral structure. The coolest object in the picture is the asteroid 3540 Protesilaos.
This Asteroid was first seen in 1973 by the German astronomer Freimut Börngen, who discovered more than 500 Asteroids while he was researching galaxies. At the time that WISE observed 3540 Protesilaos, it was at a distance of about 772 MKM from Earth (approx. 480 million miles, or also approx. 43 Light-Minutes). It is classified as a Jupiter Trojan Minor Planet, which are small rocky bodies that share the same orbit around the Sun as the planet Jupiter. Based on the infrared observations, the WISE team estimates the Asteroid to be about 90 Km (approx. 56 miles) across and to reflect only a few percent of the light that lands on it, which makes it about as dark as coal.
By convention, Trojan Asteroids are named after the heroes from the Trojan War. In this case, asteroid 3540 is named after the hero Protesilaos. According to Greek Mythology, Protesilaos was the first Greek to set foot on Trojan land during the war.
Unfortunately for him, there was a prophecy that the first soldier in the war to step onto land from a battle ship would die. The prophecy quickly came true and Protesilaos was killed.
JPL manages the Wide-field Infrared Survey Explorer for NASA's Science Mission Directorate, Washington. The principal investigator, Edward Wright, is at UCLA. The mission was competitively selected under NASA's Explorers Program managed by the Goddard Space Flight Center, Greenbelt, Md. The science instrument was built by the Space Dynamics Laboratory, Logan, Utah, and the spacecraft was built by Ball Aerospace & Technologies Corp., Boulder, Colo. Science operations and data processing take place at the Infrared Processing and Analysis Center at the California Institute of Technology in Pasadena. Caltech manages JPL for NASA.

M-101-2-PIA04632_modest.jpgM 101 - Irregular Galaxy116 visite"...Lungo le curve segnate dal moto dei pianeti, si possono distinguere i passaggi delle nostre diverse Vite. Qualcuna vissuta mangiando foglie e bacche selvatiche, insieme alla scimmie dei boschi; qualche altra camminando nel deserto, in compagnia di Assiri e Babilonesi e, forse, altre ancora in Evi più prossimi alle Stelle.
Ed io mi chiedo: come sarà la prossima?!?..."

M-057-3.jpgM 57 - The "Ring Nebula" - SST114 visite"...Vibrazioni. Frammenti di luce si stanno facendo largo tra le nebbie di questo Infinito Primordiale.
Suoni indistinti - simili ad acuti sussurri di un Vento Nuovo, che spira senza forza, ma neppure quietamente... - si spargono attraverso una distesa immensa, sfuocata, pronta ad esistere, ma ancora non viva.
Un Mondo Nuovo.
Lo sto guardando nascere e cerco di comprendere: alzo gli occhi al Suo Cielo, verso una Stella Amica, ma vedo soltanto Nuvole.
Nuvole.
Scorrono veloci e, scorrendo, emettono Vibrazioni: Frammenti di luce si insinuano fra le nebbie di un Infinito Primordiale.
Ed un raggio di Sole colpisce - finalmente - questa Nuova Terra, lanciando e lasciando istanti di colore, intorno a sè.
"...Nascentes morimur, finisque ab origine pendet..."
