Carina-Calibration-PIA07773.jpgCarina Nebula, from Cassini74 visiteCassini briefly turned its gaze from Saturn and His Rings and Moons to marvel at the Carina Nebula, a brilliant region 8.000 LY from our Solar System and more than 200 LY across. Nearly every point of light in this image is a star in our galaxy, the Milky Way.
The nebula is a region of gas and dust made to glow by the ultraviolet light bursting from bright, hot and extremely massive young stars within. Darker regions in the scene are not devoid of stars; rather, they are areas where dense clouds of dust block the light from background stars.
This image and others like it are taken by the spacecraft from time to time for calibration purposes. Calibration images rarely contain such incredible sights. This one affirms Cassini's position as the farthest, working astronomical observatory ever established around our sun - our "eyes on the cosmos", a billion miles from Earth.
The image was taken using the Cassini wide-angle camera on May 14, 2005. The view is a 68-second, clear-filter exposure.

Cartwheel Galaxy.jpgThe "Cartwheel Galaxy"83 visite"...Souls of poets dead and gone,
What Elysium have ye known,
Happy field or mossy cavern,
Choicer than the Mermeid Cavern?
Have ye tippled drink more fine
Than mine host's Canary wine?..."
John Keats (1795 - 1821) - "Lines on the Mermeid Cavern" (1820)

Cartwheel_5panel.jpgThe "Cartwheel Galaxy"99 visite"...La frase più ricorrente è "I virus non sono né forme di vita né materia inanimata".
Ma non è proprio ortodosso definire un'entità dicendo ciò che non è. Che cosa se ne ricava?
Non sono organismi biologici, non si riproducono e non si evolvono autonomamente, ma sono composti di materia, che però è dotata di mobilità.
In parole povere, i virus sono delle macchine..."

Centaurus A-SST-PIA06007_modest.jpgCentaurus A - SST108 visite"...An elliptical galaxy located 11 million light-years from Earth, Centaurus A is one of the brightest sources of radio waves in the sky. These radio waves indicate the presence of a supermassive black hole, which may be "feeding" off the leftover galactic meal.
A high-speed jet of gas can be seen shooting above the plane of the galaxy (the faint, fuzzy feature pointing from the center toward the upper left)..."

Centaurus A~0.jpgCentaurus A (Cen A) - NGC 512881 visite"...Nullum malum impunitum; nullum bonum irremuneratum..."
(Boezio)
"...Che nessuna azione malvagia rimanga impunita (e) che nessuna buona azione resti senza ricompensa..."
Da "NASA - Picture of the Day", del 4 Luglio 2006:"Why is peculiar galaxy Centaurus A so dusty? Dramatic dust lanes that run across the galaxy's center mark Cen A. These dust lanes are so thick they almost completely obscure the galaxy's center in visible light. This is particularly unusual as Cen A's red stars and round shape are characteristic of a giant elliptical galaxy, a galaxy type usually low in dark dust. Cen A, also known as NGC 5128, is also unusual compared to an average elliptical galaxy because it contains a higher proportion of young blue stars and is a very strong source of radio emission. Evidence indicates that Cen A is likely the result of the collision of two normal galaxies. During the collision, many young stars were formed, but details of the creation of Cen A's unusual dust belts are still being researched. Cen A lies only 13 MLY away, making it the closest active galaxy. Cen A spans 60.000 LY and can be seen with binoculars toward the constellation of Centaurus".
