NASA's Big Reveal: 'Lost World' Found Inside Earth, Know What Happened When Huge Meteorite Collided
Scientists have discovered evidence of Earth’s early life in ancient rocks. He observed a curious difference in the isotopes of an element called potassium. This difference suggests that it is part of the ancient Earth’s material that survived during Earth’s violent formation. This suggests that the earth’s basic building blocks are still hidden beneath its surface. How old is the earth? Scientists from MIT and other institutions have made an important discovery. They found extremely rare remains of proto-Earth, which is the earliest form of the planet and existed about 4.5 billion years ago. This planet was formed during a massive collision. What happened in this collision? This collision changed Earth’s internal chemistry forever and created the Earth we live on today. This discovery will help scientists understand the initial elements that formed not only our Earth, but the entire solar system. What was this great collision? Billions of years ago, our solar system was a swirling cloud of dust and gas. Gradually these particles combined to form meteorites. These meteorites repeatedly collided and merged to form the proto-Earth and the rest of the planets. What was the earth like in the beginning? In the early stages, the Earth was covered with molten lava. About 100 million years later, a massive collision occurred, in which a Mars-sized body collided with Earth. The collision melted the planet’s interior and nearly erased its original chemical identity. Research conducted by MIT challenges this long-held view. What was MIT’s research? Scientists have discovered an unusual chemical feature in samples of ancient, deep rock that is unlike any substance found on Earth today. This feature is a slight imbalance in potassium isotopes. A specific deficiency was found in an isotope called potassium-40. Scientists believe that this anomaly could not have been caused by any subsequent geological process. What is a remnant of the young earth? It is very likely that these rocks preserve small pieces of the original Earth’s material that somehow survived that violent collision. “This is perhaps the first direct evidence that we have preserved material from the early Earth,” says lead researcher Nicole Lee. What does this research reveal? “We are studying even earlier fragments of that giant impact,” the scientists said. This research also suggests that the original meteorites that formed the Earth may still be unknown, as the chemistry of these samples does not match any known meteorites. This discovery raises many new questions about the origin of our planet. This research was supported by NASA and MIT.
