The Geomagnetic pole is the north end of the axis of the geomagnetic field which surrounds the Earth and extends into space as the magnetosphere.
These oceans, and the fish that live there, are full of plastic, reduced to confetti, incessant from shore to shore, spread out like a spoonful of sand across a football field, over two-thirds of the Earth's surface.
An austere brick church stood in the middle of what might have been a small athletic field, the earth around it overturned by excavation.
Indeed, some at the meeting argued that if aliens were to use an astronomical phenomenon called gravitational lensing (in which the gravitational field of the sun bends and amplifies radio waves and light from Earth), human signals could be amplified to the point where even the light from cities would be visible.
ECONOMIST: An argument over whether to send messages to aliens
In southern Greenland, back in July 2004, a local man - Ferdinand Egede - dug into the soft earth of a field to show me something he'd never expected to see in his lifetime: potatoes.
It is only every 2, 000 years or so that an object the size of a football field descends to earth and causes significant damage, according to NASA. Giant asteroids that crash to earth such as the one that most likely extinguished the dinosaurs tend to occur on the scale of millions of years.
These craft will study the interaction between the solar wind (the breeze of electrically charged particles emitted by the sun) and the earth's magnetic field.
The portals, also known as X-points in Scudder-speak, are born from the mingling of Earth's magnetic field with incoming solar winds.
Bursts toward earth can cause electromagnetic storms when they react with the Earth's magnetic field, resulting in an explosion of color in the sky.
Others have put forward different ideas for how pigeons find their way, suggesting that the birds use smell, visual clues or the Earth's magnetic field, or even a combination of all of these.
The research could help test simulations of how the outer, fluid core generates the Earth's magnetic field, which shields our planet and the teeming life on it from harmful cosmic rays.

That's because as the Earth moves around the Sun, it is moving into a stationary field of dark matter - and for half the year it will be moving against the tide of dark matter - just like driving into the rain.

Earth's magnetic field gives the planet and its inhabitants a good measure of protection, but with space agencies seemingly intent on sending astronauts to the Moon and even to Mars in the next few decades, there is a pressing need for a fuller understanding of the Sun's activity.
