The Northern Lights, also called the aurora borealis, (or in Antartica the aurora australis or southern lights), are caused by the sun. Cooler spots on the sun cause solar storms that send billions of charged particles hurtling towards earth. Fortunately for us, the earth has a magnetic field that prevents particles and solar radiation from entering our atmosphere. The magnetic field comes closest to the planet at its north and south pole. At the poles particles can penetrate our atmosphere and interact with gas particles, producing beautiful colors. Oxygen produces green or red color depending upon the altitude, nitrogen is blue or purple. Our sun has an eleven-year sun cycle. The best light show occurs every eleven years at the beginning of a new cycle. The current sunspot cycle, (Number 24), runs from 2008-2019. So the end of this year or the beginning of 2020 will likely see a dramatic increase in sunspot activity.
The earth’s magnetic field is rapidly decaying. We started to measure the earth’s magnetic field in 1845. Since that time the field has decayed at the rate of 5% every 100 years! The magnetic field lost 1.4% of its energy between the years of 1970 to 2000. Based upon the current rate of decay it is unlikely that the earth’s magnetic field could possibly be much more than 10,000 years old. Without the earth’s magnetic field life on earth life could not exist. The earth’s rapidly decaying magnetic field supports the Creation account in Genesis. Maybe the Northern and Southern lights are God’s way to reside us that he created everything, in six literal days, and we can believe it.
