A new model uncovers how Earth’s liquid core has sustained its magnetic field since the planet’s beginnings, offering new insights into its future. Earth benefits from the presence of a magnetic field ...

Geophysicists have modeled how Earth’s magnetic field could form even when its core was fully liquid. By removing the effects ...

A 2D slice of the world's largest turbulence simulation, revealing the fractal structure of the density, shown in yellow, black and red, and magnetic field, shown in white. Astronomers have developed ...

Spirals of solar wind can spin off larger solar eruptions and disrupt Earth's magnetic field, yet they are too difficult to ...

For the study, the researchers modeled the influence of “flux ropes,” which are relatively smaller, tornado-like spirals of ...

This energy heats particles, creates plasma outbursts, and accelerates matter to near-light speeds. In the black hole’s ...

Most planets have a magnetic field, like Earth, but with different strength or structure. It shields the planet from the energetic particles of the solar wind. The origin of the magnetic field is ...

Astronomers have captured the clearest picture yet of how massive stars are born, revealing a dramatic interplay between ...
