NASA reports that rare, electric blue noctilucent clouds have reappeared over the South Pole, where the clouds are often spotted for five to ten days every year. NASA calls the clouds "a great geophysical light bulb" that are visible during the darkest nights.

This might look like result of some pro-level CGI, or perhaps even a glimpse into your imagination, but in fact it’s a photograph taken in Antarctica just this last week.

You’re looking at the Grand Canyon completely flooded by clouds, "a once in a lifetime event," according to park ranger Erin Whittaker. It didn’t only happen once, she says, but two times in only three days:

The problem with building man made structures in natural wonders like mountain ranges is that they can sore your eyes pretty quickly. Some parts of the world should be left untouched! But imagine a bridge like this one, designed to look like a cloud, on top of a few mountains. The views would be absolutely breathtaking and just walking the bridge would be thrilling.

Predicting how Earth’s climate will change in the coming years is a deeply important task for science. It also seems fairly fundamental—they’re just clouds! Thing is, cloud dynamics are incredibly problematic, to the point of being unknowable in some instances. More »
