1 . History could repeat itself. Solar storms have happened before and they could happen again.

About 2,700 years ago, a strong solar storm swept past the Earth. Scientists announced this in a new study.

Scientists studied ancient ice in Greenland, a part of Denmark although it is in North America. They searched to uncover clues (线索) about previous solar storms. They looked at an ice core that dated as far back as 100,000 years. In it, scientists found radiation that showed a very strong solar storm 2,700 years ago. “If that solar storm occurred today, it could have serious effects on our high-tech society,” said Muscheler, a scientist at Lund University in Sweden.

Solar storms are made up of high-energy particles (粒子) released from the sun. The releases are explosions on the star’s surface. Solar storms include different kinds of eruptions (喷发) from the sun’s surface, says NASA. Flares, sunspots and other bursts are common signs of solar activity. They all involve sudden releases of stored energy, NASA says.

The long-ago storm had little effect on people in the world. It happened before businesses and technology were everywhere. However, a solar storm of that strength would be a threat to modern society, the study said. It would cause widespread power failure. Communications, space technologies, and airline operations would also be in danger.

Scientists said this is the third known discovery of a huge solar storm in historic times. This suggests that while the storms are rare, they are a natural effect of solar activity. In other words, they could happen again. “That’s why we must increase society’s protection against solar storms,” Muscheler said. “Our research suggests that the risks are currently underestimated. We need to be better prepared.”
