Part of the Dinosaurs: Ancient Fossils, New Discoveries exhibition. Not all dinosaurs died out 65 million years ago. Avian dinosaurs–in other words, birds–survived and flourished.
How big was the asteroid that killed the dinosaurs?
The asteroid is thought to have been between 10 and 15 kilometres wide , but the velocity of its collision caused the creation of a much larger crater, 150 kilometres in diameter – the second-largest crater on the planet.
Who discovered Earth?
Eratosthenes then measured the angle of a shadow cast by a stick at noon on the summer solstice in Alexandria, and found it made an angle of about 7.2 degrees, or about 1/50 of a complete circle. He realized that if he knew the distance from Alexandria to Syene, he could easily calculate the circumference of Earth.

Can humans live on Ceres?
A ‘Megasatellite’ Orbiting Ceres Would Make a Fine Home For Humans , Scientist Says. Given all the logistics involved, it’s unlikely that humanity will ever see our way outside the Solar System to colonise exoplanets. But the possibility of settling elsewhere inside the Solar System isn’t so far-fetched.

What was before dinosaurs?
The age immediately prior to the dinosaurs was called the Permian . Although there were amphibious reptiles, early versions of the dinosaurs, the dominant life form was the trilobite, visually somewhere between a wood louse and an armadillo. In their heyday there were 15,000 kinds of trilobite.
