Darkness-0.jpgMidnight-Sun over Vastitas (by Dr Marco Faccin)60 visiteDue ricostruzioni della "gelida - e buia - alba" sopra Vastitas Borealis le quali, con tutto il rispetto per la NASA e le sue "elaborazioni", sono semplicemente splendide. Forse le due più belle interpretazioni mai realizzate sino ad ora.
Un grande complimento ed un abbraccio al sempre più "magico" Dr Marco Faccin!MareKromium

Aurora_Borealis-2.jpgAurora Borealis over Juneau57 visiteCaption NASA:"Some auroras can only be seen with a camera. They are called sub-visual and are too faint to be seen with the unaided eye. The reason is that the human eye only accumulates light for a fraction of a second at a time, while a camera shutter can be left open indefinitely. When photographing an already picturesque scene above Juneau, Alaska, USA, a camera caught green sub-visual aurora near the horizon. Auroras are sparked by energetic particles from the Sun impacting the magnetic environment around the Earth. Resultant energetic particles such as electrons and protons rain down near the Earth's poles and impact the air.
The impacted air molecules temporarily lose electrons, and when oxygen molecules among them reacquire these electrons, they emit green light. Auroras are known to have many shapes and colors". MareKromium

CosmicRays.jpgCosmic Rays58 visiteWhere do Cosmic Rays come from? A major step toward answering this century old question may have just come in from the Auger Observatory Project, the world's premier Cosmic Ray Observatory. That high energy fundamental particles are barreling through the Universe has been known for about a century.
Because ultra high energy cosmic rays are so rare and because their extrapolated directions are so imprecise, no progenitor objects have ever been unambiguously implied. New results from Auger, however, indicate that 12 of 15 ultra high energy cosmic rays have sky directions statistically consistent with the positions of nearby active galactic nuclei. These galactic centers are already known to emit great amounts of light and are likely powered by large Black Holes. The Auger results also indicate that the highest energy cosmic rays are protons, since the electric charge of higher energy nuclei would force the Milky Way Galaxy's magnetic field to deflect and effectively erase progenitor source direction.

LonelyQuasar.gifLonely Quasar...92 visite"...It was just before dawn,
One miserable morning in black, '44,
When the forward commander was told to sit tight
When he asked that his men be withdrawn,
And the generals gave thanks
As the other ranks
Held back the enemy tanks for a while,
And the Anzio bridgehead was held for the price
Of a few hundred ordinary lives..."
