The Northern Lights Won’t Be This Bright Again Until 2025
If you’ve ever camped out to see the northern lights, you know they can be elusive. They’re only visible on dark, clear nights up north when a solar flare or solar wind shoots particles toward Earth. Seeing the phenomenon live takes a bit of luck, but if spectators wish to boost their chances, now's the time. As Thrillist reports, the aurora borealis is at its peak—and won’t be this bright again until 2025.
The colorful lights that seem to bend in the sky over the Arctic Circle are the product of electrons from the Sun colliding with gases in the planet’s atmosphere. The lights are controlled by the Sun, and because solar activity goes through 11-year cycles, so does the aurora borealis.
The Sun is currently at the end of the maximum stage of its cycle. The increased solar activity makes for northern lights that are more frequent and visible farther south. As the Sun starts to move into its minimum phase of activity, the light show will be harder to see from parts of the world to the south of northern Russia, northern Canada, Alaska, and Scandinavia. The next part of the cycle will last about eight years, with solar activity starting to heat up again around 2025.
On rare occasions, the northern lights can be seen from some of the lower 48 states, like Maine, Michigan, and Washington. But to make sure you catch them in peak season, U.S. residents may have to travel north. Here are a few inexpensive trips you can take to get an eyeful of the spectacle.
