The northern lights are truly a sight worth seeing at least once in your life.
Northern lights or aurora borealis is a natural display of light in the sky mostly seen in high latitude regions.
Glacier Bay National Park in Alaska is one such sight which gives a great view of the lights.
The park posted a video of the beautiful sight to their Instagram page captioned, "Bartlett Cove put on a show last night. Without tours running, winter can be quiet in Glacier Bay but sights like this are highlights of the season":
The time-lapse video shows the lights transition across the sky over Bartlett Cove.
