Here is the article I wrote to accompany my photographs from the Gulf of Mexico impact crater. It has just been published in the US by Astronomy Magazine.
Sixty-six million years ago, a city-sized asteroid collided with Earth just off the coast of what is now Mexico. The 6-mile-wide (10 kilometers) space rock crashed down near the town of Chicxulub, some 180 miles (290km) west of Cancún. Tourists now enjoy the sunshine and warm waters here, but 66 million years ago, it was dinosaurs that claimed their place in the Sun.
I am here on behalf of the Asteroid Day/ B612 Foundation to visit an offshore drilling platform where scientists are taking core samples to study both the geology and the biology of this catastrophic event.
