The impact of a six-mile long asteroid believed to have hit the earth and wiped out the dinosaurs 66 million years ago would have sparked a cataclysmic firestorm, scientists say.
Over the past three decades scientists have argued about what caused the extinction 66 million years ago - changes to climate, volcano activity or an asteroid.
Research has already shown that the prehistoric animals died out around the same time a six-mile long object hit the planet, and a new model of the disaster suggests the asteroid's impact would have sent vaporised particles of rock high above Earth's atmosphere which in turn would have turned the sky bright red as they heated the upper atmosphere to 2,700 degrees Fahrenheit on re-entry.
