Long theorized but never observed, the first known “planet with a death wish” is described by Ilin and her colleagues in a ...

A joint venture between NASA Goddard Space Flight Center and the University of Leeds discovered that the Earth's magnetic field strength and atmospheric oxygen levels over the past 540 million ...

As Earth’s magnetic field has risen, so have the conditions that helped complex life to thrive — a discovery that could aid the search for life on distant planets. As Earth’s magnetic field ...

We should all feel grateful that we live in a time of magnetic stability, because the field acts as a protective bubble, interacting with harmful particles just beyond the outermost layer of Earth’s ...

Earth’s magnetic north is not static. Like an anchorless buoy pushed by ocean waves, the magnetic field is constantly on the move as liquid iron sloshes around in the planet’s outer core.

NASA’s LEXI, an innovative X-ray imager, is embarking on a groundbreaking mission to the Moon under the Artemis campaign. Once on the lunar surface, LEXI will capture unprecedented global images of ...

When directed at Earth, the stream of solar wind flowing from a coronal hole can impact Earth's magnetosphere, triggering geomagnetic storm conditions and resulting in impressive aurora displays.

Earth's magnetic field became weaker during this period, falling to at least 5% of its present strength. This made it possible for more cosmic rays to enter the Earth’s atmosphere, according to ...

The above graph shows the increase in the magnetic field strength, density, speed, and temperature (energy) of the particles flowing past these spacecraft (red box).

Using observations from a NASA suborbital rocket, an international team of scientists has, for the first time, successfully measured a planet-wide electric field that is as fundamental to Earth as ...
