A large coronal hole has emerged on the sun’s eastern horizon. Its fast solar wind may reach Earth, potentially triggering auroras and affecting geomagnetic activity in the coming days.

New data gleaned from the magnetic sensor aboard NASA’s InSight spacecraft is offering an unprecedented close-up of magnetic fields on Mars In a study published today in Nature Geoscience, scientists ...

Auroras are more than just beautiful lights. Scientists now use three-dimensional maps to understand auroras as monitors of space weather. This helps forecast geomagnetic storms that can affect ...

Scientists find that interplanetary shocks which strike Earth’s magnetic field head-on cause more powerful ground-level electric currents, threatening pipelines and submarine cables Auroras have ...

The sun has thrown a chunk of its plasma in the Earth's direction, which could spark minor geomagnetic storms and auroras in our atmosphere. This coronal mass ejection (CME) is due to collide with our ...

Samples reveal evidence of changes experienced by the surface of asteroid Ryugu, some probably due to micrometeoroid bombardment. Samples reveal evidence of changes experienced by the surface of ...

Beijing Zhongke Journal Publising Co. Ltd. This study is led by Postdoctoral researcher Jiawei Gao from IGGCAS. Unlike Earth, Mars lacks a global dipolar magnetic field; the planet does have locally ...

The heliosphere—made of solar wind, solar transients, and the interplanetary magnetic field—acts as our solar system's personal shield, protecting the planets from galactic cosmic rays. These ...
