New computer simulations suggest the first magnetic fields that emerged after the Big Bang were much weaker than expected — ...

Planets beyond our solar system can have magnetic fields similar to those closer to home, astronomers said Tuesday after observing extreme winds on scorching worlds known as "hot Jupiters." ...

In a new study, scientists have mapped magnetic fields in galaxy clusters, revealing the impact of galactic mergers on magnetic-field structures and challenging previous assumptions about the ...

In a first-of-its-kind discovery, astronomers claim they have directly measured the magnetic fields of multiple planets beyond our solar system — potentially providing a crucial new tool in the search ...

As with any such correlation, one has to entertain the notion that said correlation might be spurious or indirectly related before assuming a strong causal link. Here it is for example known already ...

The weak spot in Earth’s magnetic field, a region over the South Atlantic where the field’s strength is significantly reduced compared to its surrounding area, has grown by an area nearly the size of ...

Earth’s magnetic field protects life from harmful cosmic radiation. But sometime between about 590 million and 565 million years ago, that security blanket seems to have been much thinner — with ...

Within their planetary systems, stars are continuously shaping their orbiting planets through gravity, radiation and magnetic ...
