What causes the northern lights?
The northern lights are caused by charged particles from the sun colliding with gases in Earth's atmosphere.
Science / Astronomy
The northern lights, or aurora borealis, may be visible across several U.S. states due to ongoing geomagnetic storm activity. This natural phenomenon, caused by solar wind interacting with Earth's atmosphere, could create a dazzling display...
The aurora borealis is created when charged particles from the sun collide with the Earth's atmosphere. These collisions excite the atmospheric gases, causing them to emit light. The colors of the aurora depend on the type of gas and the energy of the collision. Oxygen produces green and red light, while nitrogen produces blue light.
Geomagnetic storms, disturbances in Earth's magnetic field, enhance the aurora by directing more solar particles towards the poles. NOAA's Space Weather Prediction Center (SWPC) monitors these storms and provides forecasts for aurora visibility.
To maximize your chances of seeing the northern lights: 1. Find a dark location away from city lights. 2. Look towards the northern horizon. 3. Check space weather forecasts for geomagnetic activity. 4. Use a camera with night mode to capture faint auroras.
The current solar maximum means increased solar activity and more frequent geomagnetic storms, leading to better chances of seeing the northern lights in the coming years.
The northern lights are caused by charged particles from the sun colliding with gases in Earth's atmosphere.
A geomagnetic storm is a disturbance in Earth's magnetic field caused by solar activity.
The best time is between 10 p.m. and 2 a.m. local time, away from city lights, during periods of high geomagnetic activity.
