http://www.euronews.com/ Earth's magnetosphere is an invisible shield, protecting our planet from harmful solar radiation. • Many living organisms - from bacteria to insects or birds - seem to rely on Earth's magnetic field to navigate. Man has been doing so for a thousand years since the invention of the compass. • But research shows the magnetic field is weakening and scientists are trying to understand why. • Some believe it signals a pole reversal in progress, not an uncommon phenomenon in the history of our planet. • As ground observatories fail to grasp the whole picture, we are sending magnetometers into orbit to try to measure the magnitude and the direction of the magnetic field. • Find out more, this week, in Space. • Find us on: • Youtube http://bit.ly/zr3upY • Facebook / euronews.fans • Twitter / euronews
