A team of researchers affiliated with several institutions in Japan and France has found evidence that suggests the Earth's outer core is made of more than just liquid iron. In their paper published in the journal Physical ...
Impact cratering both produces new regolith and causes seismic events that can degrade and erase small craters on the surface of asteroids, a paper by Planetary Science Institute Senior Scientist James Richardson says.Â
