Tethys-PIA07662.jpgGrand Canyon on Tethys67 visiteA crescent Tethys shows off its Grand Canyon, Ithaca Chasma, for which the moon is renowned. The chasm is about 100 Km (app.x 60 miles) across on average, and its up to 4 Km (about 2 miles) deep in places.
Ithaca Chasma is the most prominent sign of ancient geologic activity on Tethys, whose surface is characterized principally by heavy cratering.
The lit surface visible here is on the moon's Saturn-facing Hemisphere. North on Tethys is straight up.
The image was taken with the Cassini spacecraft narrow-angle camera on Nov. 28, 2005 using a filter sensitive to wavelengths of infrared light centered at 930 nnmts. The view was acquired from a distance of app.x 1,1 MKM (equivalento to about 700.000 miles) from Tethys and at a phase angle of 123°. Resolution in the original image was 6 Km (about 4 miles) per pixel. The image has been magnified by a factor of two and contrast-enhanced to aid visibility.

OGLE.jpgOGLE 2005-BLG-390Lb - ExtraSolar Planet67 visiteThis Artist's illustration shows an icy/rocky planet orbiting a dim star. Astronomers detected an Extrasolar Planet that is five times as massive as Earth, circling a red dwarf - such as a relatively cool star - every 10 years. The distance between this Planet, designated OGLE-2005-BLG-390Lb, and its host is about 3 times greater than that between the Earth and the Sun (means about 240/250 MKM).
The Planet's large orbit and its dim parent star probably make its surface temperature a frigid -364° Fahrenheit (about -220° Celsius).

M-008-0.jpgM 8 - The "Lagoon Nebula"67 visite"...Oltre alle coincidenze inspiegate ed agli intenzionali occultamenti dei fatti, un altro tarlo minaccia il nostro attuale metodo scientifico ed anzi probabilmente è il più pericoloso di tutti.
Mi riferisco alla cronica incapacità dell’essere umano di trarre le ovvie conclusioni, anche di fronte all’evidenza più sfacciata. Non mi riferisco evidentemente alla percentuale di credibilità delle giustificazioni di mogli e mariti infedeli, ma a nozioni che, pur essendo apparentemente di patrimonio comune, in realtà non sono “arrivate” mai nella conoscenza collettiva..."

SOL746-PIA02187.jpgHome Plate Panorama - Sol 74667 visiteThis week, NASA's Spirit arrived at Home Plate, a feature that, when seen from orbit, looks like the home plate of a baseball diamond. Home Plate is a roughly circular feature about 80 mt (260 feet) in diameter that might be an old impact crater or a volcanic feature. The Spirit Team has been eager to get to Home Plate and has been enjoying distant views of the feature and a curious "bathtub ring" of light-colored materials along its edges. The Team has pushed the Rover hard to get here before the deep Martian winter sets in.
After scientists had identified Home Plate from orbit, they had many theories about what it could be and what they might see. But when Spirit's Pancam took this and other images, the Science Team was stunned. This PanCam image is of an outcrop nicknamed "Barnhill" and surrounding rocks on the north side of Home Plate, showing the most spectacular layering that Spirit has seen.
Pancam and MI views of the layers in the rocks reveal a range of grain sizes and textures that change from the lower to the upper part of the outcrop. This may help scientists figure out how the material was emplaced. Spirit is also conducting work with its arm instruments to figure out the chemistry and mineralogy of the rocks. Scientists have several hypotheses about what Home Plate could be, including features made by volcanoes and impact craters, and ways that water could have played a role. They are busy trying to figure out what the data from Spirit is really telling us.
As Spirit works at Home Plate during February, the science team is choosing informal names for rocks from the great players and managers of the Negro Leagues of baseball. This outcrop, "Barnhill," is informally named for David Barnhill, the ace of the New York Cubans' pitching staff during the early 1940s. He compiled an 18-3 record in 1941 and defeated Satchel Paige in the 1942 East-West all-star game. Other rocks in the area are informally named for Josh Gibson, "Bullet Joe" Rogan, and Cumberland Posey. Stay tuned this month, as the Baseball Hall of Fame elects more players from the Negro Leagues and Spirit continues to examine these spectacular rocks.
