High above the landscapes of Lapland, something extraordinary happens. Charged particles from the Sun travel toward Earth, where our planet’s magnetic field guides some of them into the upper atmosphere. There, they collide with gases—including oxygen.
Those collisions transfer energy to oxygen atoms. As the atoms release that energy, it becomes visible as light. At the altitudes where many auroras occur, oxygen produces the brilliant green that has come to define the northern lights.
There is something remarkable about that transformation. Oxygen, an element so closely connected with life on Earth, becomes part of an entirely different phenomenon high above it—one where energy, atmosphere and light come together to create colour across a darkened sky.
Unlike the pigments drawn from earth, this is a colour that cannot be gathered, ground or mixed. It exists for a moment, constantly changing with the conditions that create it.
Some colours can only be witnessed. This one, you can write with.
