According tomedia reports, it turns out that dinosaurs had far worse luck than we thought. While a huge asteroid hitting The Earth never bodes well, a new study suggests that space rocks hit the Earth at the deadliest angle, maximizing the catastrophic climate change that follows.
About 66 million years ago, an asteroid at least 10 kilometers in diameter hit what is now Mexico’s Yucatan Peninsula. The impact destroyed three-quarters of life on Earth at the time, including dinosaurs and 93 percent of mammals.
Although death comes fairly quickly for creatures that are unfortunately too close to the impact zone, most of the creatures on Earth die out of the series of subsequent climate effects. Large amounts of vaporized rocks, sulfur, carbon dioxide and water vapor are fed into the atmosphere, where they block the air and block the sun. In summary, the sky darkened over an 18-month period, killing most photosynthesis plants and crushing the food chain on land and in the sea.
Now, a new study has calculated the angle of impact and the direction of the asteroid. To do this, researchers from Imperial College London, the University of Freiburg and the University of Texas at Austin studied the shape and structure of the Hicksuluber crater.
The three parts of the crater can reveal the story behind the impact together. They include crater centers, peak craters, and mantle rocks.
Discover how the centers of these three regions are arranged to infer the direction and angle of the asteroid. In this case, all the centers are arranged in a southwest-northeast direction. The center of the crater itself is in the middle of the line, between the peak ring and the center of the mantle.
When the researchers made a 3D simulation of the impact, they determined the version of the event that was closest to the features observed in the crater. According to the team, the asteroid hit Earth at an angle of about 60 degrees from the northeast.
“We know that this is one of the worst-case scenarios for the impact because it sends more dangerous debris into the upper atmosphere and spreads them around ——– this is what led to the nuclear winter,” said lead researcher Careth Collins of the study. “
This is not the first study to study how unlucky dinosaurs really are. A few years ago, a group of Japanese researchers found that if an asteroid hit almost anywhere else on Earth, the subsequent extinction event might not have been as severe because the impact site was rich in hydrocarbons, which led to more carbon smoke being emitted into the atmosphere. Only 13% of the Earth’s surface has this devastating effect, and that’s where it hit.
