Learn how starquakes, subtle vibrations inside stars, revealed hidden magnetic fields in red giants and how this stellar ...
For the first time, new theoretical models, published in Astronomy & Astrophysics, connect the magnetism at the surface of ...
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 ...
