This crater in Yucatan conceals secret asteroids who killed dinosaurs



In the mid-1980s, a group of American archeologists carefully studied satellite imagery of the Yucatan Peninsula in Mexico and confused what looked like a nearly perfect ring, about 200 kilometers wide.

Experts have discovered this pattern – surrounding the capital of Yucatan, Merida, and the port cities of Sisal and Progreso, while trying to figure out what happened to Maya's civilization after the reign of the peninsula, but a strange circular form confused the researchers when they presented their findings on satellites during the scientific conference called Selper in Acapulco, Mexico, 1988.

For Adriana Ocampo, then a young planetary geologist at NASA, the circular formation sounded familiar.

"As soon as we saw the points, I thought: Yeah, a moment, this is something incredible, this could be …" said Ocampo, now director of NASA's Lucy program, who will send a spacecraft to Jupiter's Orbit in 2021.

"I was really excited from the inside, but I was silent because you obviously do not know (for sure) until you have more evidence," he told BBC News.

As he approached the scientists with a sharp heart, Ocampo wondered whether he was considering the impact of the asteroid, one giant and violent enough to mark the planet in a way that can still be seen 66 million years later.

"They did not even know what I was talking about," says expert, laughing, three decades later.

But Ocampo believes it will lay the foundations of what most scientists today believe in this ring: to fit the edge of the twelve-kilometer asteroid crater that hit the Yucatan and exploded with unimaginable force. turned from rocks to liquid.

Since the early 1990's, teams from scientists from America, Europe and Asia have been working on discovering the secrets that this place has. Now they believe that the strike has just created a 30-mile crater depth, causing the Earth to function as a pond after a fall, due to the power of rejection, a mountain is created that is twice the height of Mount Everest, albeit for a moment.

In the years following the cataclysms, the world would have changed and would sink into the dark of the night for more than a year, while the Earth temperature was below zero and about 75 percent died on the planet, including virtually all dinosaurs, but without that influence , humanity may not have existed.

"It has given us the advantage that we can compete, so we can progress, as we possibly did," said the expert.

Today, where everything happened, the impact was buried a kilometer below the small town of Chicxulub Puerto, a few thousand people, with low buildings painted yellow, white, orange and ocher that surround the humble place.

At first glance there are no indications that this was a scene of one of the consequent and catastrophic consequences of the last 100 million years of the Earth.

Originally, the idea that a giant asteroid destroyed dinosaurs was suggested by Luis and Walter Alvarez in the early 1980s. "But then it was extremely controversial," Ocampo said.

While in 1978, geophysicist Glen Penfield, along with Antonio Camargo-Zanoguer, investigated the Caribbean waters crossing the Chicxulub Puerto coast in search of oil for Pemex. Using a magnetometer, Penfield searched for water for signs of oil, but found half the huge crater, however, the information was owned by Pemex and was not available to the scientific community.

A Texan reporter named Carlos Byars wrote an article for the Houston Chronicle in 1981 that links Yucatan's ring with Alvarez's asteroid theory. Later, Byar shared his theory with a degree in Alan Hildebrand and found that the crater was not a volcano, but an asteroid's influence.

"[Byars] He was confessed that he was the first to compile complications, a journalist, "Ocampo said." It's an amazing story when you put all the pieces, "he added.

And once again, the story is confirmed, the scandals of the asteroid impact on Mars have shown similarities to the Chicxulub crater, indicating that Mars had to have a much greater atmosphere than now, closer to the atmosphere than supporting Earth's life. "It's important that we know what happened in the past to be ready for the future," Ocampo said. "It provides a really good look at what happened in the geological evolution of Mars," he said.

But in the Chicxulub crater, many incredible knowledge remains buried beneath the earth. There is little that visitors can see because the influence was long ago. Tourists visiting one of the few remnants of impressions, impressive cenotes, where you can swim among the fish and the lush tree roots, do not ignore that these geological features exist only because the soft limestones from which they were made were forced to the surface by the depth of the underworld stroke.
