Discovering the Mysteries of the Northern Lights: A Deep Dive
Written on
Chapter 1: Understanding the Northern Lights
On May 10, 2024, at a latitude of 43° 5' 23" N, I was fortunate enough to witness the northern lights from my backyard.
I captured stunning photographs and shared them on social media, proudly telling my friends about the spectacle. However, I soon found myself questioning, what exactly are the northern lights?
The Sun: Our Vital Star
The sun, a typical star amidst billions in the Milky Way galaxy, plays an essential role in our existence. Positioned approximately 93 million miles from Earth, it is a massive sphere composed of gas and plasma, which is a superheated state of matter containing charged particles. This plasma continuously escapes from the sun’s outer layer, known as the corona, creating the solar wind.
Every 11 years, during a solar cycle, a solar maximum occurs, resulting in a more potent solar wind that allows individuals in lower latitudes, like myself, to discuss the wonders that unfold.
The Earth: Our Unique Home
Earth, orbiting this crucial star, is a seemingly random rock, yet it holds immense significance for us. The presence of various metals allows our planet to generate its own magnetic field, surrounded by a complex atmosphere primarily made of gases.
What Are the Northern Lights?
As the solar wind nears Earth, the planet’s magnetic field channels the charged particles toward the poles. When these particles collide with the gases in our atmosphere, atoms—predominantly nitrogen and oxygen—become excited. This excess energy is then emitted as light.
This dazzling display, observed near the North Pole, is known as the northern lights (aurora borealis), while its counterpart near the South Pole is called the southern lights (aurora australis). During periods of solar maximum, this phenomenon can even be visible far from the poles. However, these remarkable events can also disrupt satellites, communication systems, and power grids; I personally experienced a brief power outage the following morning.
A Couple of Songs to Set the Mood
After absorbing the science behind the lights, I concluded my night with some music to match the magical atmosphere.
“Northern Lights” by St. Vincent
For those of you who enjoy deep, introspective indie rock, this track perfectly captures the essence of the experience.
“Die a Happy Man” by Thomas Rhett
For the more laid-back, fun-loving crowd, this song offers a lighter vibe that complements the wonder of the night sky.
