In first order the magnetic field created by this magnet is that of a dipole whose axis is tilted with respect to the spin axis by about 11 degrees. ... The difference between the dipole axis and geographic axis is one of the reasons why there are so many different coordinate systems needed to describe locations in space around the Earth. The area around the Earth governed by its magnetic field is called the magnetosphere . ...

... It is only a matter of time before astronomers find an Earth-sized planet orbiting a distant star. We will naturally ask whether the planet is habitable or bears life. But will we be able to tell if there are bacteria, roaming dinosaurs, or even more advanced life? ... In the past twelve years, scientists have discovered more than two hundred large planets orbiting other stars, yet finding Earth-like planets is a fascinating and substantially more technologically demanding endeavor. ...
