The surface of Mars "funnel" depression that raises concerns about the existence of life or hide the key clues to the scientists think that the surface of Mars found a strange depression is likely to be hidden on the Red Planet survival "key clues" Sina Technology News Beijing on November 15th news, according to the British "Daily Mail" reported that scientists believe the surface of Mars, found a strange depression is likely to be key clues hidden on the Red Planet survival "". For a long time, scientists believed that the name "Heelas" (Hellas) depressions terrain is hidden by subglacial volcano formed, and more recently, researchers have conducted in-depth analysis of the use of high-definition stereo images and digital elevation model, and tries to find more secrets behind it. The latest research shows that the terrain indeed in many shows on earth with similar genetic characteristics of ice volcano volcano, which means that it may produce a sufficient warm environment, which contains the chemical composition of liquid water and life need to survive. This is the first in the terrain was first discovered in 2009, when researchers at NASA’s Mars Reconnaissance Orbiter (MRO) for HD images on attention to such a strange ring fracture system, a bit like the earth Iceland or Greenland ice kind of volcano dome. The Heelas basin depression structure of Mars on the strange appearance, surrounded by some of the ancient glacial sediments around the earth, this kind of structure is in the ice beneath the volcano eruption left on the surface trace, and on Mars, this environment there is a possibility of life. The first author of the study, University of Texas Institute of Geophysics assistant researcher Joseph levy (Joseph Levy) said: "we are here to attract attention, because it seems to hold some life elements needed — water, heat and nutrients etc.." This bizarre looking structure is located in the Heelas basin (Hellas basin), surrounded by some ancient glacial deposits. The researchers also called a "Galactic trench" (Galaxias Fossae) the region noticed a similar landform. Levi said: "these geomorphic features attract our attention, because they look very unique. It’s a concentric rift system that looks like a bull’s eye. If this kind of landform is observed on the earth, it should be very conspicuous." In this study, the researchers used a pair of high definition images to create a three-dimensional digital elevation model of the region, so as to be able to study the structure of the region in the 3D environment. This study provides a clear picture for researchers, help to ascertain whether the structure is indeed as volcano causes, or the product of an impact event.
