The enigma of the asteroid has been solved: the ‘dark’ origins of the dinosaur-killing space rock have been revealed.
SCIENTISTS think they’ve found the source of the killer asteroid that killed out the dinosaurs 66 million years ago.
The gigantic dinosaurs were the dominating living form on Earth until the end of the Cretaceous epoch. All of that changed when a six-mile-wide (10-kilometer) asteroid collided just off the coast of what is now Mexico’s Yucatan Peninsula. The so-called Cretaceous-Paleogene Impact is thought to have caused the dinosaurs’ untimely extinction by generating thousands of years of terrible climate change.
Although there has never been unanimity on where the asteroid originated from, and many questions remain unresolved, this is the most widely accepted hypothesis concerning what happened to the dinosaurs.
“Two crucial ones remaining unanswered are: ‘What was the source of the impactor?’” stated Dr. William Bottke of the Southwest Research Institute (SwRI) last month. and ‘How often have similar impact events occurred on Earth before?’
According to previous research, the killer asteroid could have been a comet from the solar system’s outermost reaches.
Others have speculated that the asteroid is a fragment of a bigger object known as Baptistina.
SwRI scientists believe they have finally found the asteroid’s origin in the asteroid belt that circles the Sun between Mars and Jupiter.
According to their research, a primitive and “black” rock from our system’s main asteroid belt may have triggered the Cretaceous-Paleogene Impact.
SwRI scientists discovered that the asteroid belt delivers huge boulders hurtling our way 10 times more frequently than previously assumed, using a combination of computer calculations and actual observations.
More importantly, the makeup of these asteroids is identical to that of the Chicxulub asteroid that collided with the Mexican coast.
Thousands of old rocks range in size from 33 feet (10 meters) to 329 miles (530 kilometers) across the asteroid belt.
The cumulative mass of all asteroids in the belt, according to NASA, is less than that of our Moon.
Beyond Neptune’s orbit is another ring of primordial space objects known as the Kuiper belt.
According to NASA, the solar system contains more than 1.1 million known asteroids.
According to David Nesvorny, a researcher at SwRI in Colorado, one of these boulders slammed into our globe 66 million years ago.
