DISCOVER MAGMA in LUNA. Scientists have discovered a large plume of magma beneath the largest of the Moon Sea. Its origin remains a mystery, as despite being similar to the cracks in the Earth, where the crust and lithosphere are separating, the Moon has no tectonic plates could cause divisions. The finding proves that the moon is much more dynamic than previously thought. (Mauricio MF) Scientists have discovered a large plume of magma beneath the largest of the Moon Sea. Its origin remains a mystery, as despite being similar to the cracks in the Earth, where the crust and lithosphere are separating, the Moon has no tectonic plates could cause divisions. The finding proves that the moon is much more dynamic than previously thought. The astronomer scientist Jeffrey Andrews-Hanna, the Colorado School of Mines in the United States, and colleagues analyzed data collected by the probe GRAIL (Gravity Recovery and Interior Laboratory) spacecraft, which helped create a detailed map of gravity on the moon. They found a mysterious box in Oceanus Procellarum which had higher density. Oceanus Procellarum (Ocean of Storms) is the largest of the lunar maria, ie, large, dark plains formed by ancient volcanic eruptions that cover about 16% of the lunar surface. Located on the near side of the Moon, covering about 2,500km north to south. A greater than the sum of France, Italy, Spain and Portugal area. The team concluded that the increased density in the area was caused by magma, which is heavier than the crust of the Moon. It is believed to be the remains of a plumbing system geology that our satellite lava spilled about 3.5 million years ago. The initial cracks became grabens that were filled with magma and pushed crustal blocks. The extra weight caused the collapse of the region, giving the appearance of a basin. The existence of this formation indicates that, in the beginning, the Moon was much more geologically active than previously thought, with significant volcanic and tectonic activity. The discovery also collapses the old theory that Procellarum basin or is a giant crater created by the impact of an asteroid. blog.meteorologiaespacial.es/2014/10/05/descubren-magma-en-la-luna/
