Latest Chicxulub crater Stories
The massive asteroid that crashed into the ocean near the coast of Mexico millions of years ago (and is believed to have wiped out the dinosaurs) was likely the catalyst for a series of worldwide volcanic eruptions contributed to the extinction event, new research claims.
For the first time, scientists plan to conduct an expedition to collect and analyze core samples from the 125-mile-wide Chicxulub impact site in Mexico, a crater believed to have been caused by the asteroid that wiped out the dinosaurs more than 65 million years ago.
A nearly 250 mile (400 km) wide impact zone recently discovered in Central Australia is being called the largest asteroid-caused craters ever discovered, according to research published earlier this month in the international earth sciences journal Tectonophysics.
Researchers claim to have uncovered new evidence supporting the notion that a Manhattan-sized asteroid collided with the Earth some 66 million years ago, triggering a global firestorm that would have led to the extinction of 80 percent of the planet’s species.
According to Jason Moore from Dartmouth College, who presented a study at the 44th Lunar and Planetary Science Conference, evidence from the Chicxulub crater suggests there are possibilities beyond an asteroid impact.
Scientists have winnowed the precision of the dates regarding the extinction of the dinosaur and the well-known impact that occurred around the same time.
A cosmic one-two punch of colossal volcanic eruptions and meteorite strikes likely caused the mass-extinction event at the end of the Cretaceous period that is famous for killing the dinosaurs 65 million years ago.
Seeking to better understand the level of death and destruction that would result from a large meteorite striking the Earth, Princeton University researchers have developed a new model that can not only more accurately simulate the seismic fallout of such an impact, but also help reveal new information about the surface and interior of planets based on past collisions.
The Chicxulub crater in Mexico, the site of the asteroid strike that brought the dinosaurs to extinction 65 million years ago, is among the highlights of ocean drilling projects proposed for the next decade.
A new study theorizes that the dinosaurs were wiped out 65 million years ago by at least two meteorite strikes rather than one.
