New evidence suggests that water on Mars is 1 billion years longer than previously thought havd707

New evidence suggests that the water on Mars is 1 billion years longer than previously thought, and scientists have discovered some new canyons near the heart lake on Mars, much later than the canyon before. The low and high elevation areas are white and purple, while the high elevation areas are yellow. This string of lakes and valleys connected up to 90 miles (about 150 km). Lake water storage capacity of about 2790 cubic kilometers, more than the North American lakes of Ontario, more than five. Sina science and technology news Beijing time on September 19th news, we already know that in a certain period of history, and now arid barren Martian surface has been covered by a vast ocean. But as to when this period is over, a new study has subverted our predictions. Scientists once believed that the "wet" period of Mars occurred about 4 billion years ago, when it was the first single celled life on earth. Today, 1 billion years later, new evidence suggests, Mars is still covered with lakes and rivers. This means that the microbial life on Mars may be 1 billion years longer than we thought. NASA researchers made the discovery by determining the formation time of 22 craters on mars. "We found a few rivers that flow into the lake." The Smithson institution of Washington Sharon? Werwilson (Sharon Wilson) said, "some lakes are filled with water, and even spill out, indicating that the Martian water very well." Wilson and his colleagues discovered the evidence on the surface of the land in the northern part of Mars by studying the images of the Mars Reconnaissance orbiter. In addition, they also used NASA’s Mars Global Surveyor probe and ESA’s Mars Express probe returned data. "One of the lakes in this area is almost as good as Too vast lake." Wilson said. Too vast lake is located between California and Nevada, with about 188 cubic kilometers of water. "The water of this Martian lake is supplied by a canyon on the south side, which overflows from the north and flows into a very large basin." This string of lakes and valleys connected up to 90 miles (about 150 km). Lake water storage capacity of about 2790 cubic kilometers, more than the North American lakes of Ontario, more than five. The streamline structure in the Martian Canyon is formed by the water that has been formed in a lake formed hundreds of millions of years ago. The geological structure is located in the land of the Arab Israeli plain, about 8 miles in diameter (about 12.8 km). The researchers map the range of water in the shallow valleys, and the ancient lakes connected to them. In order to determine the age of these ancient lakes, the researchers estimated the formation time of 22 craters in the area. They wanted to find out if the canyon had been left on the surface of the rubble that was ejected from the crater, to determine whether the canyon was formed before or after the crater. And they came to the conclusion that…相关的主题文章:
