A huge solar storm, that was about 10 times stronger than any other one recorded in modern history, is believed to have hit the Earth nearly 2600 years ago, a recent study has found. Scientists made the conclusion after examining samples of ice cores and tree rings taken from Greenland, thus detecting trapped radioactive atoms that indicate a gigantic proton storm struck the planet in about 660 B.C.
Don't panic. Yes, astronomers suggest that it's very likely that a "dark matter hurricane" will slam into the Earth as it speeds through the Milky Way -- but it shouldn't cause any damage. In fact, in the hunt for the mysterious particle (or particles) that makes up dark matter, the "hurricane" may provide our best chance at detection.
