Repeated impacts can create minerals that lock in magnetic signals long after the Moon’s global field has disappeared.

Although magnetic forces are usually much weaker than gravity in shaping cosmic structures, the findings suggest that strong, ordered magnetic fields may have emerged earlier than expected. Over time, ...

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 ...

In the air people breathe, the water on Earth, the stars in the sky and more, atoms are the building blocks that make up the ...

This video explains what magnets are and how magnetic fields are generated through the alignment of atomic structures. Magnets influence electric currents, force interactions, and are used in many ...

(Nanowerk News) MIT physicists have created a new ultrathin, two-dimensional material with unusual magnetic properties that initially surprised the researchers before they went on to solve the ...

Primordial magnetic fields may help explain why measurements of the universe’s expansion do not agree. Scientists have long known that the universe is expanding, yet there is still no agreement on how ...

Like Earth, Mars once had a strong magnetic field that shielded its thick atmosphere from the solar wind. But now only the magnetic imprint remains. What's long baffled scientists, though, is why this ...

Add Yahoo as a preferred source to see more of our stories on Google. One of the most peculiar things about Uranus and Neptune is their magnetic fields. Each of these planets has a hot mess of a ...

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 ...

Computer simulation of a one-sided magnetic field on early Mars based on data from a study led by the University of Texas Institute for Geophysics. The study could explain the unusual magnetic imprint ...
