Thus, while a tessera/plains/rifts evolution is a valid hypothesis, that evolution could not have occurred as a "catastrophe". The highly varying levels of post-impact volcanism and deformation that the craters have experienced are consistent with a steady state model of Venus resurfacing.
"Current models indicate that Venus may have been habitable. Complex life may have evolved on the highly irradiated Venus, and transferred to Earth on asteroids. This model fits the pattern of pulses of highly developed life appearing, diversifying and going extinct with astonishing rapidity through the Cambrian and Ordovician periods, and also ...
The ancient Hebrews, like all the ancient peoples of the Near East, believed the sky was a solid dome with the Sun, Moon, planets and stars embedded in it. [4] In biblical cosmology, the firmament is the vast solid dome created by God during his creation of the world to divide the primal sea into upper and lower portions so that the dry land could appear.
Tessera terrain in the Maxwell Montes seen in white on the right of the image. Eastern edge of Lakshmi Planum seen in gray on the left. A tessera (plural tesserae) is a region of heavily deformed terrain on Venus, characterized by two or more intersecting tectonic elements, high topography, and subsequent high radar backscatter. [1]
A simple Venus global strata base on Ivanov and Head's model (2011) (Note that it is just a simple global strata, not every region on Venus has this strata.) Under the Global stratigraphic Classification Scheme, by correlating the units mentioned above (Mikhail A. Ivano and James W. Head, 2011), [ 13 ] the researchers suggested three phases of ...
Model of crustal plateau and tessera terrain formation via mantle downwelling after Gilmore (1998). Venus In situ Composition Investigations ( VICI ) is a concept lander mission to Venus in order to answer long-standing questions about its origins and evolution, and provide new insights needed to understand terrestrial planet formation ...
Venus's atmosphere is rich in primordial noble gases compared to that of Earth. [95] This enrichment indicates an early divergence from Earth in evolution. An unusually large comet impact [96] or accretion of a more massive primary atmosphere from solar nebula [97] have been proposed to explain the enrichment. However, the atmosphere is ...
The surface of Venus is comparatively flat. When 93% of the topography was mapped by Pioneer Venus Orbiter, scientists found that the total distance from the lowest point to the highest point on the entire surface was about 13 kilometres (8.1 mi), about the same as the vertical distance between the Earth's ocean floor and the higher summits of the Himalayas.
