There are several theories about how the Earth and the Moon were formed, most involving a giant impact. They vary from a model where the impacting object strikes the newly formed Earth a glancing blow ...

First ever supercomputer simulations of Mars with a fully molten core could explain the Red Planet's unusual magnetic field. Billions of years ago, Mars had an active magnetic field. Mysteriously, its ...

Researchers at Massachusetts Institute of Technology have demonstrated an entirely new form of magnetism in a synthesized crystalline material. They're calling it p-wave magnetism. This discovery is ...
