National Park Shares Beautiful Aurora Borealis Footage With Green Hues In Alaska

This dazzling footage shows an incredible aurora borealis lighting up the night sky with bright green colours in Alaska.

The footage was shared by Glacier Bay National Park and Preserve, which is an American National Park located in south-eastern Alaska, west of Juneau.

They captioned their post: “For much of the summer, the sun stays up too long to allow for stargazing or aurora viewing, but on Monday night and earlier last weekend the aurora and dark starry skies returned! Many skywatchers across northern latitudes saw one of the first shows of this aurora-season.

“Clear skies can be rare this time of year in Glacier Bay, with clouds retaking the sky at the end of this timelapse clip.”

Auroras are caused by disturbances in the magnetosphere as a result of solar wind. Charged particles including electrons and protons end up in the upper atmosphere where they are ionised, and this is what causes the incredible light show for anyone lucky enough to catch a glimpse of it in the night sky.

The timelapse footage shows the sky turning a bright shade of green before clouds eventually rolling and the show ends.
