Lunar Eclipse.jpgLunar Eclipse over England87 visiteDa "NASA - Picture of the Day", dell'11 Settembre 2006:"Last Thursday - Sept., 7th, 2006 -, part of our Moon turned dark. The cause, this time, was not a partial lunar phase - the Moon was full - but rather that part of the Moon went into Earth's shadow. The resulting Partial Lunar Eclipse was visible from the Eastern Atlantic Ocean through Europe, Africa and Asia and into the Western Pacific Ocean. The darkest part of the Lunar Eclipse, when part of the Moon was completely shielded from Sunlight, lasted about 90 minutes.
Pictured here, a partially eclipsed Moon is seen rising over an estate in Huddersfield, England. The above image was taken far away from the house in the foreground, as only this would allow it to appear as angularly small as the half-degree Moon far in the background. A setting twilight Sun lit the foreground. The next eclipse of the Moon will occur in March 2007".Set 11, 2006

Aurora.jpgGreen Aurora98 visiteDa "NASA - Picture of the Day" del 6 Settembre 2006:"What if your horizon was green? If you've got a camera, take a picture! That was the experience of Jeff Hapeman last week when visiting the Pictured Rocks National Lakeshore in Michigan. On a quiet night toward the Northern Horizon over Lake Superior was a long lasting diffuse green aurora. The above image was taken in an effort to capture the sense of wonder one gets when watching an auroral display. 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".Set 09, 2006

M 31 and Hale Bopp.jpgTemporary Sky...78 visiteDa "NASA - Picture of the Day" del 13 Agosto 2006:"The Moon almost ruined this photograph. During late March and early April 1997, Comet Hale-Bopp passed nearly in front of the Andromeda Galaxy.
Here the Great Comet of 1997 and the Great Galaxy in Andromeda were photographed together on 1997 March 24th. The problem was the brightness of the Moon. The Moon was full that night and so bright that long exposures meant to capture the tails of Hale-Bopp and the disk of M31 would capture instead only moonlight reflected off the Earth's atmosphere. By the time the Moon would set, this opportunity would be gone. That's why this picture was taken during a total lunar eclipse".Ago 13, 2006

Perseid-2.jpgShooting Star (2) - detail mgnf93 visiteOsservate questo ingrandimento della Perseide immortalata dal nostro Amico Jimmy Westlake e poi provate a riguardare il (presunto) bolide che Cassini potrebbe aver fotografato nello Spazio di Saturno: noterete con semplicit che le caratteristiche delle due "strisciate di luce" (streaks) sono MOLTO simili.
Peccato che la NASA si affanni a dare credito solo ad alcuni personaggi e ad alcune (sempre pi discutibili o insulse) "scoperte" (come il presunto colorito "rosato" di Iperione), senza mai prendere atto che anche in Italia esistono Ricercatori attenti e competenti i quali, di tanto in tanto, sono i primi a notare l'esistenza di qualcosa di veramente raro...
Peccato.Ago 11, 2006

Perseid-1.jpgShooting Star (1)89 visiteL'immagine sicuramente bella, ma quello che vorremmo farVi notare la tessitura della striscia lasciata dalla "stella cadente" la quale, come ben si vede (anche senza operare ingrandimenti), contiene "nodi" (modesti rigonfiamenti dovuti, probabilmente, a perdita/consunzione di materiale a seguito dell'attrito durante la caduta del frammento di Corpo Celeste attraverso l'atmosfera) e "brillamenti" (delle vere e proprie "fiammate" che si avviano, di regola, in corrispondenza dei "nodi" e che indicano cambi di temperatura - ergo di luminosit - del Corpo in questione).Ago 11, 2006
