Saturn-PIA08936.jpgA Planetary "Smile", from Saturn...57 visiteCaption NASA:"Brooding Saturn seems to be missing its rings, but their shadows on the Planet betray their presence. The inner rings are in fact contained within this scene, but they are so tenuous as to be nearly invisible.
This view looks toward the unilluminated side of the Rings from about 52° above the Ring-Plane. Some motion is apparent in Saturn's clouds between the exposures used to create this color composite, as evidenced by the 'rainbow' effect seen here and there across the face of the Planet.
Images taken using red, green and blue spectral filters were combined to create this natural color view. The images were taken with the Cassini spacecraft wide-angle camera on April 5, 2007 at a distance of approx. 1,5 MKM (about 900.000 miles) from Saturn.
Image scale is roughly 84 Km (about 52 miles) per pixel".MareKromium

South_Polar_Regions-1.gifVenusian South Polar Vortex through Venus Express (2)57 visiteThis composite video sequence was obtained by the Ultraviolet, Visible and Near-Infrared Mapping Spectrometer (VIRTIS) on board ESA’s Venus Express.
The single images were taken from 7 to 11 April 2007 over 5 different orbits. In each orbit the images were collected during a time span of 8 hours and were separated by about half an hour. The average distance from the Planet was about 65.000 Km.
The Latitude of the observed area spans from 90 to 50° South. The Longitude spans from about 20 to 150° East.
The video shows details of the Planet’s South Pole with edge-enhanced contrast.
Using specific wavelengths (3.8 and 1.7 microns, respectively), the observations allowed the imaging of the day and night areas around the South Pole simultaneously, at different depths (at about 65 Km and below the cloud deck, respectively) simultaneously. The intersection between the polar atmospheric structures seen at different wavelengths is visible in good detail, due to the optical properties of the clouds.MareKromium

OPP-SOL1176-1M232582439EFF82__P2936M2M1.jpg"Newborn" Berries in the crack? - Sol 1176 (False Colors; credits: Lunexit)57 visiteNella crepa (crack) di questa roccia (che - presumiamo - potrebbe anche essere una porzione della Pavimentazione Marziana più prossima ad Opportunity) si distinguono piuttosto chiaramente dei Martian Berries. L'ipotesi tradizionale (e, sicuramente, la più accreditata) ci dice che si tratta di mini-berries (ossìa di sferule rocciose appena più grandi dei granelli di sabbia che potremmo trovare su qualsiasi spiaggia terrestre) i quali, trasportati/spinti dal vento, sono rimasti intrappolati nelle fenditure delle rocce e pavimentazioni vicine al margine di Victoria Crater. Sarà andata realmente così?
Forse. O forse no.
Ci piacerebbe capire, infatti, per poter rispondere adeguatamente, se questa crepa che vediamo è effettivamente una crepa, oppure se si tratta di una fenditura la quale congiunge la superficie di Marte ad un (probabilmente molto attivo, caldo e, forse, in parte vitale) sottosuolo.
Insomma, la nostra (esotica, lo ammettiamo) domanda è: questi "berries" si sono infilati nella crepa dall'esterno (ribadiamo, poichè spinti dal vento e/o da altre forze che appartengono all'ambiente marziano "aperto"), oppure essi stanno fuoriuscendo dall'interno della roccia?
Pensateci anche Voi...MareKromium

M-042-PIA09412.jpgOut of Orion's Head (2)57 visiteThis image from NASA's SST shows infant stars "hatching" in the Head of the Hunter constellation, Orion. Astronomers suspect that shockwaves from a supernova explosion in Orion's head, nearly 3 MY ago, may have initiated this newfound birth
The Region featured in this Spitzer image is called Barnard 30.
It is located approximately 1300 LY away and sits on the right side of Orion's "Head" just North of the massive star Lambda Orionis. Wisps of red in the cloud are organic molecules called polycyclic aromatic hydrocarbons. These molecules are formed anytime carbon-based materials are burned incompletely. On Earth, they can be found in the sooty exhaust from automobile and airplane engines. They also coat the grills where charcoal-broiled meats are cooked.
This image shows infrared light captured by Spitzer's infrared array camera. Light with wavelengths of 8 and 5.8 microns (red and orange) comes mainly from dust that has been heated by starlight.
Light of 4.5 microns (green) shows hot gas and dust; and light of 3.6 microns (blue) is from starlight.
