Earth’s magnetic field, the invisible barrier that deflects solar radiation and makes surface life possible, is not permanent in its current orientation. Geologic records show that magnetic north and ...

Learn how titanium-rich lunar rocks and Apollo landing sites reshaped researchers’ understanding of the Moon’s early magnetic history.

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 ...

The Earth's magnetic field and oxygen evolved together over 540 million years, according to a major NASA study.

It is generally considered certain that the Moon did not have a strong magnetic field in its early days. However, samples ...

Indian astronomers have investigated an ultraluminous X-ray pulsar in the galaxy NGC 4631, designated X-8. The new study, described in a paper published Feb. 16 on the arXiv preprint server, provides ...

Earth’s magnetic field can linger in a weakened, unstable state for tens of thousands of years before fully flipping.

The Sun’s magnetic poles are in the middle of an uneven, drawn-out reversal as Solar Cycle 25 moves through its solar maximum ...

A new model contradicts previous theories that the sun's magnetic field originates deep inside its interior. Deep origin theories could not explain rotation patterns of the sun's gas near its surface ...

For a few brief nights each year, you get a rare chance to watch a monster blink. The Event Horizon Telescope collaboration ...

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 ...
