Given the crucial role the planet's magnetic field plays in guiding navigators and protecting Earth from solar storms, scientists know surprisingly little about it.

On Earth, a strong magnetic field and a thick atmosphere help protect life from radiation blazing from the sun and the rest of the universe.

Then there's the even greater problem of protecting the body from cosmic radiation — a role Earth's natural magnetic field does for us quite nicely.

How the magnetic field of the CME interacts with Earth's magnetosphere, the magnetic shell covering and protecting the planet, determines how severe any terrestrial effects will be, notes Gombosi, who has built models of the interaction.

Thus, the atmosphere could have eroded too soon, even if the exoplanet was protected by a strong magnetic field like the magnetosphere surrounding Earth, Dong said.

During that time, scientists believe that Earth lacked a solid core and thus had a much weaker magnetic field — something required to protect life on Earth from DNA - damaging radiation.

Fortunately for surface - dwelling humans, Earth's magnetic field and atmosphere do a good job protecting us from such killer electrons.

Earth's magnetic field and atmosphere protect us on the ground from most of the harmful effects of space weather, but astronauts in low - Earth orbit — or even, one day, in interplanetary space — are more exposed to space weather, including bursts of fast - moving particles called solar energetic particles, or SEPs.

They found that even an Earth - like magnetic field could not necessarily protect a habitable - zone world from the star's continuous bombardment.

Earth is protected from solar eruptions and space weather by its magnetic field.

Spacecraft in low - Earth orbit, such as the shuttle and the International Space Station, are protected from these particles by the Earth's magnetic field, but astronauts travelling farther afield would not benefit from this protection.

Luckily for us, Earth is protected by a magnetic field, Yeager says.

The earth's magnetic field performs important functions: it protects us, for example, from charged particles from space and enables migratory birds, bees, and other animals to navigate.

Earth is protected from a similar fate only by its strong magnetic field, which guides the solar wind around the planet.

Earth's inhabitants are largely protected from cosmic radiation by the planet's atmosphere and magnetic field, but long - term residents of the moon would be exposed to potential cellular and genetic damage without proper shielding.

Radiation levels on the ISS are 100 times greater than on Earth because the station is not protected by the planet's atmosphere and magnetic field.

Earth's geomagnetic field surrounds and protects our planet from harmful space radiation.

Earth's magnetic field should protect us against these rays, but geomagnetism is weakening.

On Earth, life is protected, sustained and developed under the planet's magnetosphere — a space controlled by the planet's magnetic field.

Despite being one of the three terrestrial spheres blessed with a global magnetic field (with the other two being Earth and Jupiter's moon Ganymede), Mercury's invisible shield will not protect future explorers from the wrath of the Sun.

In 2010, model simulations of rocky super-Earths between two and 10 Earth - masses indicated that high pressures could keep their cores solid instead of molten, which would prevent a protective magnetic field from forming protecting developing surface life from stellar radiation.

«The magnetic field would have caused the solar wind to stand off from the atmosphere, as it does on Earth, and thereby protect the atmosphere.

The planet itself lacks a global magnetic field, which typically protects planets like Earth from solar wind, maintaining the atmosphere.

This, scientists say, is potentially very good news, as we could use the barrier to protect Earth from extreme space weather resulting from events like coronal mass ejections — huge explosions on the sun, where plasmas and magnetic field are ejected from its corona, the outermost part of its atmosphere.

The earth's magnetic field protects us from charged particle radiation, not from electromagnetic waves (which are 99.9999 % the cause of solar heating).

Article by Phil Livermore, Associate Professor of geophysics, University of Leeds and Jon Mound, Associate Professor of Geophysics, University of Leeds The Earth's magnetic field surrounds our planet like an invisible force field — protecting life from harmful solar radiation by deflecting charged particles away.
