"This is especially critical in arid environments in which water resources are severely taxed already." "There is a wealth of information stored in these sediments that can be used to determine how hydrologic systems responded to abrupt climate change in recent times," Pigati said. In the future, the researchers hope to analyze wetland deposits and black mats to learn more about the history of water flow and climate change, rather than cosmic collisions. While their findings don't completely dismiss the Younger Dryas impact hypothesis, Pigati and his team suggest scientists need to look for alternative ideas to explain these markers thought to involve cosmic impacts. Based on the concentrations and relative abundances of these elements, the researchers concluded the samples came from terrestrial sources. To figure out whether the wetlands had trapped earthly or cosmic dust, the researchers analyzed the samples for their rare earth elements, or a group of 17 metallic elements with similar structures and properties. It really shows how pervasive the markers can become in such environments." "We were certainly excited, however, to see the consistency of our findings across continents and different time periods. "Many of us familiar with wetlands and black mats thought that the 'impact markers' might be concentrated by natural processes," researcher Jeff Pigati, a geologist at the U.S. Specifically, they may have been caused by accumulation and concentration of dust, a phenomenon common to wetlands - the wet ground and dense plant cover found in those areas makes them effective dust traps. Instead, these markers were instead created by naturally occurring terrestrial processes. The fact that these markers are present in sediments of different ages and from various locations suggests they were not produced by a single catastrophic event such as an impact, researchers said.

NASA has been streaming photos from Mars ever since their robot Curiosity landed in August 2012. People also believe that the ancient Pyramids of Giza were a prodcuct of alien architecture, although no prove has been discovered by anyone in this matter. This is one of hundreds of similar artefacts that I have found on Mars in recent years and may go further to show that there was an ancient and artistic civilisation on Mars in the past,” he added.Ī month ago, Barry DiGregoria, an astrobiologist at the University of Buckingham had similar viewpoint about the statue image, and he claimed that Mars had experienced life in the past years. “It has a possible emblem on the forehead and some very interesting facial features that look almost Egyptian in artistic style. ![]() It resembles a carved depiction of a female warrior wearing a helmet similar to some found on Earth from the Middle Ages,” the 45-year-old video journalist said. “I have found what seems to be a small feminine looking statue head on Mars in Gale Crater in this recent Curiosity Rover image from NASA.
