After extensive research, scientist are now saying that the asteroid that killed the dinosaurs may have gone all the way through the Earth's crust. They say that this is exciting because it caused new habitats and such. This is also opening up the study of asteroids hitting other solar system objects such as other planets and such. They have also been looking at the objects on newly found craters and have found materials on them, that co exist on the moon and other planets. I think this is super cool because it shows how something that could be called a disaster has opened up a new door to science and could help create many new discoveries.
