Clouds, stars, and aurora borealis display in the night sky above, and reflected in the glassy surface of Lake McDonald, Montana. As a night sky watcher, I look forward to some amazing opportunities in 2014 to witness dancing aurora. In the meantime though, and as a celebration of the arrival ofthis year's winter solstice
here are some spectacular photographs capturing the interactions between our sun and the planet we call home.
Northern lights (aurora borealis) above snow covered mountains at a fjord in the Norwegian arctic. The solar wind from the sun carries charged particles that are drawn by Earth's magnetic fields to the poles. In the high northern and southern hemispheres the solar wind particles collide with molecules and gas atoms in Earth's atmosphere. The interaction emits a glowing light that ripples across the sky.
A 15 second time exposure shows the International Space Station passing above the aurora borealis as viewed From Blackduck Minnesota on the night of June 6, 2013. The Station, with its 250- to 260-mile-high orbit, flies well above the aurora that is caused by the interaction of charged particles and the upper atmosphere at an altitude of 80 to 200 miles.

During the winter solstice on Saturday, daylight hours will be at a minimum for the year -- providing northern night-sky watchers with a longer opportunity to see the vivid colors of any potential aurora displays.

The night of Oct. 10, 2013, and into the very early hours of Oct. 11, north of Wasilla, Alaska, brought an incredible display of the aurora borealis over many parts of the state. Here they are seen over Willow, Alaska, and reflected on a small pond near Nancy Lake.
