But instead of a shower of icy particles, it's the Earth's magnetic field that gets pushed into a long trail directed away from the Sun. Five spacecraft from ESA - the 4 Cluster spacecraft and DoubleStar - recently observed how this magnetotail can experience strange turbulence through its interaction with the Sun's solar wind and coronal mass ejections. How and why this phenomenon happens is still a mystery. Full Story Related Stories Discuss this Story
