The immense Chicxulub crater is a remnant of one of the most consequential days in the history of life on Earth. The asteroid strike triggered the Cretaceous-Paleogene, or K-Pg, mass extinction.
The findings further support the theory that the dramatic impact was the cause of the mass extinction The Chicxulub impact crater, roughly 180 kilometers in diameter, is the best-preserved large impact structure on Earth. It is also the best example of the types of impact craters that were produced on Earth during a period of heavy bombardment more than 3800 million years ago. Space dust found in Chicxulub crater has proven that the impact of the asteroid and the extinction of the dinosaurs are “indisputably linked.” Some 66 million years ago, all non-avian dinosaurs on Earth were abruptly wiped out, and a growing body of research identifies the culprit as an asteroid impact in present-day Mexico. A Chicxulub-kráter (ejtsd: tʃikʃuˈlub) egy óriási, ősi becsapódási kráter, melynek nyomai a mexikói Yucatán-félszigeten, illetve annak közelében, a tengeraljzaton maradtak fenn.  170 kilométeres átmérőjével az ismert becsapódási kráterek közül a közepes méretűek közé tartozik. 15 Feb 2021 The Chicxulub impactor, as it's known, was a plummeting asteroid or Development of Space and is pursuing a master's degree at the New 12 Nov 2018 Chicxulub Puerto, Mexico, is the centre of the impact crater that scientists believe was made when the asteroid that wiped out the dinosaurs 15 May 2017 How different Earth's history might have been if the space rock had struck a different Chicxulub Crater - The impact that changed life on Earth.
Some 66 million years ago, dinosaurs on Earth were wiped out, and a growing body of researchers supports the theory that the main culprit was an asteroid impact in what is present-day Mexico as against the theory that volcanism in Deccan A team of scientists dug into Chicxulub crater, which is the scar left over from the impact that is located on the Yucatan Peninsula in Mexico.There, they retrieved rocks from between 1,640 feet The view from space lets scientists see some of Chicxulub's surface features that are not nearly so obvious from the ground. Satellite images showing a necklace of sink holes, called cenotes, across the Yucatan's northern tip are what first caught the attention of NASA researchers Drs. Kevin Pope, Adriana Ocampo and Charles Duller in 1990. New evidence found in the Chicxulub crater suggests the black carbon that filled the atmosphere after an asteroid struck Earth 66 million years ago was caused by the impact and not massive wildfires. Chicxulub had little to do with the extinction at the K/T. Chicxulub data was released by the oil companies because it was in a good place to hide other nearby impacts of interstellar objects.
Most theories suggest Chicxulub was a massive asteroid; hundreds May 3, 2016 An expedition eighteen miles off the coast of Mexico is drilling into the seafloor to probe the crater created by the Chicxulub asteroid, the space Oct 30, 2020 PRNewswire/ -- A new study reveals that the Chicxulub impact crater and its A principal author of that concept, Universities Space Research Nov 17, 2016 An artist's impression of what the Chicxulub crater might have looked like soon after an asteroid struck the Yucatán Peninsula in Mexico. Dec 19, 2019 Hike around impact craters like Meteor Crater in Arizona or swim in a cenote near Chicxulub Crater in Mexico. Learn about volcanic craters like Dec 20, 2018 The cataclysmic Chicxulub impact roughly 66 million years ago spawned a tsunami that produced wave heights of several meters in distant Feb 18, 2021 Where the Chicxulub impactor came from is a matter of debate.
In spite of these immense measurements, the crater is hard to see, even if you're standing on its rim. To get a good map, NASA researchers examined it from space. Ten years before the 1990 discovery of the Chicxulub crater, physicist Luis Alvarez and geologist Walter Alvarez, a father-son team, proposed a theory about the impact that created it.
That anomaly is shown here with a picture of the analyzed core sample that contains debris that settled through the post-impact atmosphere. Data from Goderis et al.

Its devastating impact brought the reign of the dinosaurs to an abrupt and calamitous end, scientists say, by triggering their sudden mass extinction, along with the end of almost three-quarters of the plant and animal species
Core material retrieved from the Chicxulub crater site is under study. Photo: IODP Though this space dust is present in low quantities all over Earth, the study published in Science Advances found it is four times more concentrated in the Chicxulub impact crater than in the surrounding area.
