PangeaUltima_scotese_big.jpgA VERY far, distant and yet possible Future: Pangea Ultima55 visiteIs this what will become of the Earth's surface? The surface of the Earth is broken up into several large plates that are slowly shifting.
About 250 MY ago, the plates on which the present-day continents rest were positioned quite differently, so that all the landmasses were clustered together in one supercontinent now dubbed Pangea. About 250 MY from now, the plates are again projected to reposition themselves so that a single landmass dominates.
The above simulation from the PALEAOMAP Project shows this giant landmass: Pangea Ultima.
At that time, the Atlantic Ocean will be just a distant memory, and whatever beings inhabit Earth will be able to walk from North America to Africa.MareKromium

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When he asked that his men be withdrawn,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..."

NoctilucentClouds.jpgNoctilucent Clouds over Sweden70 visiteCaption NASA:"Sometimes it's night on the ground but day in the air. As the Earth rotates to eclipse the Sun, sunset rises up from the ground.
Therefore, at sunset on the ground, sunlight still shines on clouds above. Under usual circumstances, a pretty sunset might be visible, but unusual noctilucent clouds float so high up they can be seen well after dark.
Pictured above last month (September 2007), a network of noctilucent clouds cast a colorful but eerie glow after dusk near Vallentuna, Sweden.
Although noctilucent clouds are thought to be composed of small ice-coated particles, much remains unknown about them. Satellites launched to help study these clouds includes Sweden's Odin and NASA's AIM.
Recent evidence indicates that at least some noctilucent clouds result from freezing water exhaust from Space Shuttles".MareKromium

CosmicRays.jpgCosmic Rays55 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.

Aurora_Borealis-2.jpgAurora Borealis over Juneau54 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

Aurora_Borealis.jpgAurora Borealis over Chena Lakes54 visiteCaption NASA:"Sometimes, after your eyes adapt to the dark, a spectacular sky appears. In this case, a picturesque lake lies in front of you, beautiful green aurora flap high above you, brilliant stars shine far in the distance, and, for a brief moment, a bright meteor streaks by. This digitally fused breathtaking panorama was captured late last month across one of the Chena Lakes in North Pole, Alaska, USA, and includes the Pleiades open cluster of stars on the image right. The shot is unusual not only for the many wonders it has captured simultaneously, but because lakes this far north tend to freeze and become non-reflecting before a sky this dark can be photographed".MareKromium
