The Event Horizon Telescope's polarized view of Sagittarius A*. The lines mark the orientation of polarization related to the magnetic field around the black hole's shadow.EHT Collaboration A new ...

Roughly 42,000 years ago, Earth’s magnetic field weakened dramatically during the Laschamps geomagnetic excursion, allowing more cosmic radiation to reach the atmosphere. In a peer‑reviewed study of ...

A new model that posits the same physical process is responsible for magnetic field and the rotation patterns, contradicting previous theories that the sun’s magnetic field originates deep inside its ...

Forbes contributors publish independent expert analyses and insights. David Bressan is a geologist who covers curiosities about Earth. Nov 28, 2025, 07:59am EST Map of the strength of the Earth's ...

The Earth’s magnetic field, a silent guardian against harmful solar radiation, has been behaving strangely in recent years. This has sparked many questions and concerns about the implications of such ...

A new photo of the supermassive black hole at our galaxy's core looks different from those before. Scientists released the photo, captured by telescopes from around the globe, on Wednesday. The image ...

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 ...

This illustration lays a depiction of the sun's magnetic fields over an image captured by NASA’s Solar Dynamics Observatory. The complex overlay of lines can teach scientists about the ways the sun's ...
