The Great Aurora

Aurora

Not being a scientific person, I have never understood what causes an aurora borealis to appear in the sky. According to National Geographic they are created “when charged solar particles collide with molecules in Earth’s atmosphere, infusing the molecules with extra energy that then gets emitted as light.” Uh huh. All I know is to see them in person has got to be absolutely amazing. Last month, a cloud of charged particles from the sun slammed into Earth which set off a geomagnetic storm that caused northern lights to spread across the U.S. This was such a large event that the auroras were seen in more than half the 50 states, including Texas and the Deep South. In some places the lights weren’t visible to the naked eye, but could be seen through long-exposure photographs. In others they were so bright that they seemed to create a big, red spot in the middle of all of the green.
