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.

July's Last Quarter Moon Is Coming This Weekend

If you scan the sky after the sun sets this Sunday, July 12, you’ll see this month’s last quarter moon. And if you’re a novice sky-gazer, you might be surprised to find that half—not a quarter—of the moon is illuminated.

The name isn’t related to how much of the moon is visible, but rather, which phase of its monthly orbit around Earth it’s currently in. The Old Farmer’s Almanac suggests picturing the cycle like a baseball diamond: A new moon (which you can’t see at all) is home plate; a first quarter moon is first base; a full moon is second base; and a third (or last) quarter moon is third base. In other words, the last quarter moon marks the last quarter of the cycle before we get another new moon. And since we can see half of it, it’s sometimes colloquially called a half moon.

As EarthSky reports, July’s last quarter moon hits its peak at 7:29 p.m. EDT on Sunday night, but you can wait until the sky gets darker for a clearer view. Though it’s not the last last quarter moon of the year, this one is extra special. Since it peaks just four hours after the lunar apogee—the point in the moon’s orbit when it’s farthest from Earth—July’s last quarter moon will be farther from the Earth than any other quarter moon this year.

It won’t appear noticeably dimmer or more distant to the naked eye, but it’s still a cool fact to mention to whomever happens to be around on Sunday night. On the following nights, you can watch the waning crescent grow slimmer and slimmer until the moon disappears completely on July 20 and starts the cycle over again.
