Astronomers believe that they have discovered the origin of the asteroid that wiped out the dinosaurs.

The six mile-wide asteroid which struck the Earth 66 million years ago and ended the 180 million year-long reign of the dinosaurs, was the cause of what is known as a Chicxulub events. It landed in what is now the Yucatan peninsula in Mexico and formed the Chicxulub crater.

Scientists had examined the remains of the ancient rock through the samples on the Earth and within drill cores, which revealed that the debris came from a carbonaceous chondrite class of meteorites – some of the most pristine material in the entire solar system.
