Exoplanet habitability depends on a whole host of factors, with liquid water at the top of the list. It also requires a ...

This persnickety number determines the strength of magnetic fields. It figures in everything from motors and generators to ...

Earth's magnetic field originates in the outer core and extends out into the magnetosphere — a region of space that helps protect Earth from space weather.

How far out does the Earth's magnetic field extend? Is the ISS inside it? How well protected is the ISS? Is the magnetic field weaker out there?

Illustration of the global coronal magnetic field as the sun rotates. The background is the solar corona observed in extreme-ultraviolet waveband, with global coronal magnetic field maps measured ...

Modelling extreme magnetic fields and temperature variation on distant stars Date: October 13, 2020 Source: University of Leeds Summary: New research is helping to explain one of the big questions ...

The Earth’s geomagnetic field, which scientists have been warning about for hundreds of years, isn’t about to suddenly flip over after all, according to a new study. It now looks like the ...

The reason magnetic fields are so important is that they can shield a planet from solar wind and ionizing particles. Mars could get one through Phobos.
