Antarctica is getting fully into the swing of summer -- and there that can mean an entire day of sunlight. Here's what that looks like.
The above panoramic image was stitched together from the ESA's Concordia research base in Antarctica by a visiting UK physician, Eoin Macdonald-Nethercott. During Antarctic winter, areas can go for weeks without seeing the sun -- the flipside of that is that in the summer, you get periods of no sunset in those same areas.
That means that, instead of sunrise or set, you can watch the sun snake across the sky over the span of a full day. With winter's short days still well-ahead of us, it makes a lovely contrast.
