Let’s Begin…
Why do we see those stunning lights in the northern- and southernmost portions of the night sky? The Aurora Borealis and Aurora Australis occur when high-energy particles are flung from the Sun’s corona toward the Earth and mingle with the neutral atoms in our atmosphere -- ultimately emitting extraordinary light and color. Michael Molina explains every step of this dazzling phenomenon.

Color: If you’ve seen the polar lights or looked at pictures you’ve noticed that they appear in a variety of colors. This has to do with the atoms that are being excited and the size of their wavelength. Find out more about the colors of the polar lights.
Wind: Science is always making breakthroughs thanks to technology and instruments we have built over the years. Wind is a solar probe that helped capture solar wind.
