Imagine you are taking a bus home at night. Suddenly your cellphone loses its signal. The television on the bus has no programs. Everything around us black-except for some strange colorful lights dancing in the sky. What is going on?
These are just the kinds of problems a solar storm might cause. Solar storms happen when solar flares (耀斑)break from the sun and travel towards Earth quickly. Actually, since Sept.4, 2017, the sun has burst out two big solar flares, the most powerful ones since at least 2008 according to NASA. They hit Earth on Sept.7.
Normally, Earth is protected by its magnetic field (磁场). But when strong solar storm mix with it, things change. On the one hand, the colourful lights of the aurora (极光)can be seen from the US and Europe, rather than just from polar (极地的)areas. But on the other hand, the storms can stop the satellite systems that control our computers, cell phones and GPS. They can even cause blackouts (断电) for weeks or months.
, but they can put astronauts in danger. Spacewalking astronauts might have only minutes to hide. For this reason, NASA never plans spacewalks during solar storms.
Scientists now have a new tool called EEGGL, which can predict solar storms and hopefully give us warnings when they arrive. As for the recent storm, scientists say it is still too early to know its effect on our technology. They are closely watching for any long-term effects.
