Active_Sun.jpgActive Sun (Credits: Mehmet Ergün)106 visiteCaption NASA Originale:"Our Sun is becoming a busy place. Only two years ago, the Sun was emerging from a solar minimum so quiet that months would go by without even a single sunspot. In contrast, already this year and well ahead of schedule, our Sun is unusually active, already nearing solar activity levels seen a decade ago during the last solar maximum. Our increasingly active Sun was captured two weeks ago sporting numerous interesting features. The image was recorded in a single color of light called Hydrogen Alpha, color-inverted, and false colored. Spicules carpet much of the Sun's face. The brightening towards the Sun's edges is caused by increased absorption of relatively cool solar gas and called limb darkening. Just outside the Sun's disk, several scintillating prominences protrude, while prominences on the Sun's face are known as filaments and show as light streaks. Magnetically tangled active regions are both dark and light and contain cool sunspots. As our Sun's magnetic field winds toward solar maximum over the next few years, whether the Sun's high activity will continue to increase is unknown".

Cosmic_Ray_-_1.jpgSpark in the Dark (possible Anomaly; credits: Dr M. Faccin)187 visiteDue frames consecutivi i quali ci evidenziano il verificarsi di un "brillamento" nello Spazio di Saturno.
Le stelle fisse che caratterizzano i due quadri Vi aiuteranno a verificare come un qualcosa di indefinito (nel primo frame) diventa brillante al punto da produrre un artifact (il TIPICO artifact) da over-saturazione.
Questi sono fatti. Tutto il resto (che potete aggiungere Voi stessi) è, ad oggi, solamente speculazione.MareKromium

SOL902-3.jpgDark Mars - Sol 902 (Darkened Natural Colors; credits for the additional process. and color.: Dr Gianluigi Barca - Lunexit Team) 56 visiteMarte è un mondo "luminoso" tanto quanto lo è la Terra? Probabilmente no. Non siamo a livello di perpetuo (e scuro) crepuscolo (a meno che non ci si trovi in Inverno e nelle Regioni Polari e Presso-Polari, sia a Nord, sia a Sud), ma certo è che il giorno pieno di Marte - se non altro per come lo vediamo dopo aver processato le immagini NASA-RAW - non deve essere proprio un "trionfo di luce"...MareKromium

ZZ-Mercury-Terminator-PIA11372.jpgDawn on Mercury (HR - possible True Colors; credits: Lunexit)58 visiteThe first image taken following MESSENGER’s closest distance to Mercury (PIA11352) during the mission’s recent flyby was a Wide Angle Camera (WAC) image. The image shown here is the first NAC image acquired after closest approach, and since the resolution of the NAC is a factor of seven higher than that of the WAC, this image is the highest-resolution image obtained during MESSENGER’s second Mercury flyby.
The image was taken near local dawn, so the shadows are long and many features are shrouded in darkness. The right side of this image overlaps with the left side of the previously released close-up view of Machaut crater (see PIA11249), which was taken just 5" later than this image. This portion of Mercury’s Surface is heavily cratered, with small craters visible down to the limits of even this highest-resolution image.
Date Acquired: October 6, 2008
Image Mission Elapsed Time (MET): 131770803
Instrument: Narrow Angle Camera (NAC) of the Mercury Dual Imaging System (MDIS)
Resolution: 100 meters/pixel (0,06 miles/pixel)
Scale: This image is about 100 Km (approx. 63 miles) across
Spacecraft Altitude: approx. 3800 Km (about 2400 miles)MareKromium

Knobs-20080722a-PCF-LXTT.jpgNorthern Knobs and Ejecta Blanket (Enhanced Natural Colors; credits for the additional process. and color.: Dr Paolo C.

The ejecta pattern and doublet crater look like a fancy butterfly flying West".

Knobs-Deuteronilus_Mensae-20080514a-PCF-LXTT.jpgHighly Reflective "Knobs" in Deuteronilus Mensae (Enhanced Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team)58 visiteDifficile dare una spiegazione (al di là della over-saturation del frame - idea razionale ma che, a nostro avviso, in questo caso non tiene...) per giustificare l'albedo elevatissima dei lati esposti al Sole di queste colline "a ceppo" (knobs).
Il Prof. Hoagland, quando si trovò in una situazione visiva simile (a proposito della Sfinge di Cydonia), disse che l'albedo elevata poteva giustificarsi solo pensando ad un residuo di "piastrellatura vetrosa" della "Sfinge" (o "Faccia di Marte") la quale, colpita dai raggi radenti del Sole del primo mattino, brillava come un faro.
Beh, Cari Amici, che dire? Una cosa è certa: se la Sfinge brillava (e brilla) così perchè era ed è "piastrellata", allora anche queste collinette sono "piastrellate"...

PSP_006567_2220_RED_abrowse-01.jpgFlooded terrain in Terra Sabaea (extra-detail mgnf - MULTISPECTRUM; credits: Lunexit)70 visiteThe smooth surfaces of the flows are punctuated by curved, subparallel fractures oriented transverse to the flow direction.
These cracks resemble crevasses in terrestrial glaciers and were formed when the brittle solid crust of the flow fractured as it was dragged downstream. Detailed images such as this will help determine the role ice may have played in these flows.MareKromium
