Auroras have long been fascinating to scientists and stargazers alike, and now experts have an even better understanding of the mysterious phenomenon. A new study, published in Nature Communications, has revealed the secrets behind the formation of auroras.

This research has found that the auroras are created by a combination of two processes. The first is the impact of powerful solar winds on Earth’s magnetic field, which causes particles to be flung towards the atmosphere. The second is the collision of these particles with the gases in the atmosphere, which then produce the stunning light displays of greens, blues, and reds. This research offers a new and comprehensive understanding of how auroras form, and the process by which they can be observed in the sky.
