Valhalla Basin on Jupiter's moon Callisto, taken by Voyager 1. A multi-ringed basin (also a multi-ring impact basin) is not a simple bowl-shaped crater, or a peak ring crater, but one containing multiple concentric topographic rings; [1] a multi-ringed basin could be described as a massive impact crater, surrounded by circular chains of mountains [2] resembling rings on a bull's-eye.
The depth of an impact crater in a solid planet or moon may be measured from the local surface to the bottom of the crater, or from the rim of the crater to the bottom. Crater depth diagram. The diagram above shows the full (side) view of a typical crater. Depth "A" measures from the surface to the bottom of the crater.
Euler's Tonnetz. The Tonnetz originally appeared in Leonhard Euler's 1739 Tentamen novae theoriae musicae ex certissismis harmoniae principiis dilucide expositae.Euler's Tonnetz, pictured at left, shows the triadic relationships of the perfect fifth and the major third: at the top of the image is the note F, and to the left underneath is C (a perfect fifth above F), and to the right is A (a ...
For example, it is only 28% the size of Earth's Moon and 41% that of Pluto, another dwarf planet. It is comparable in size to Saturn's moons Tethys and Dione . Ceres' small size means that it cooled much faster than full-sized planets and larger moons, limiting its degree of thermal evolution.
The Darvaza gas crater (Turkmen: Garagum ýalkymy), [1] also known as the Door to Hell or Gates of Hell, officially, the Shining of Karakum, is a burning natural gas field collapsed into a cavern near Darvaza, Turkmenistan. [2] Hundreds of natural gas fires illuminate the floor and rim of the crater. The crater has been burning since the 1980s.
More recent evidence suggests the crater is 300 km (190 mi) wide, and the 180 km (110 mi) ring observed is an inner wall of the larger crater. [19] Hildebrand, Penfield, Boynton, Camargo, and others published their paper identifying the crater in 1991. [10] [16] The crater was named for the nearby town of Chicxulub Pueblo. Penfield also ...
In "Fifth House" (based on "Hot House", i.e. "What Is This Thing Called Love") the standard substitution is implied over an ostinato bass pattern with no chordal instrument instructed to play the chord changes. When Coltrane's improvisation superimposes this progression over the ostinato bass, it is easy to hear how he used this concept for his ...
The crater wall of Beethoven is buried by its ejecta blanket and by plains materials and is barely visible. [2] The floor of the basin is covered with intermediate smooth plains material, which has the same reflectance as the exterior intermediate terrain. However, there are no wrinkle ridges or graben inside the basin like those in Caloris. [4]
