It is much easier to get to Mars than to get deep inside this planet, so for all our knowledge about things like earthquakes and the magnetic field, Earth's interior is actually very poorly understood. To study how metals interact at the prodigious pressures within, scientists squeeze small particles in the lab and heat them up — but this is an inexact science and difficult to do.
Thanks to a highly sophisticated x-ray machine, scientists can now peer inside fossilized animals without destroying a hair

In an opening scene of Jurassic Park, a scientist with a syringe pierces a translucent glob of amber to extract dinosaur DNA from a prehistoric mosquito. While clearly the stuff of science fiction—no liquid would exist in the fossilized resin, among other things—the study of insects frozen in time this way is very much science fact. And the paleontologists at the European Synchrotron Radiation Facility in Grenoble, France, have developed an exceptionally high-tech method for carrying out that study. Theyre able to capture signs of ancient life in amber which is completely opaque.
