Earth’s magnetic field has long been framed as a planetary force field, a protective bubble that keeps the worst of the Sun’s radiation at bay. Increasingly, though, scientists are finding that this ...

It used to be thought that there were more volatiles than expected in lunar soil because they escaped Earth before it had a stable magnetic field. Researchers who ran simulations of these atmospheric ...

In mid-December of 2024, scientists officially updated the World Magnetic Model (WMM), which helps keep track of our planet’s magnetic north and its chaotic and relatively unpredictable movements.

A theoretical new paper argues that atmospheric metal pollution from falling space junk could create an invisible conductive shield around our planet that might weaken our magnetosphere. However, ...

Earth's magnetic field protects the surface from solar wind and cosmic radiation. However, according to a new study about 42,000 years ago, this shield failed, leading to widespread environmental ...

University of Leicester engineers have unveiled a magnetic cloak device that hides or shields an object from external ...

Mars is the next big frontier of human space exploration, but it’s hardly a hospitable world. While there have been many proposals for making the Red Planet a bit more cozy, NASA scientists have now ...

Each time the sun hurls a planet-size cloud of charged particles toward Earth, there’s a potential for power outages and satellite damage. But it’s when the magnetic field carried by these billion-ton ...

NASA claimed the magnetic shield is weakening at 5% per decade, so what percentage is left as of today? originally appeared on Quora: the place to gain and share knowledge, empowering people to learn ...

A particle detector being prepared for launch Friday aboard space shuttle Endeavour is intended to answer some fundamental questions about physics, but it has a practical side as well — testing a way ...

DENVER — A group of undergrad students is developing a magnetic shield to defend interplanetary astronauts from the intense cosmic radiation between Earth and Mars. The students, from Drake University ...
