Helio Highlights: May 2025
The Sun is 93 million miles away, but its presence is felt strongly even at this distance. One of the more beautiful effects of this presence are the auroras which light up the sky in the Northern and Southern polar regions. These displays, also called the Northern and Southern Lights, are caused by interactions between particles of energy from the Sun and the molecules in the atmosphere above Earth’s poles.
