I just knew there was bad news about it.

Nacreous clouds-also known as polar stratospheric clouds-contribute to the formation of the polar ozone holes. The clouds form surfaces where chemical reactions can take place that produce ozone-destroying molecules.

"These clouds are more than just a curiosity," added Andrew Klekociuk, an atmospheric scientist with the Australian Antarctic Division. "They reveal extreme conditions in the atmosphere and promote chemical changes that lead to destruction of vital stratospheric ozone."

I looks like the virgin mary. Or maybe that Scream painting on its side.

I still think these clouds look cooler:

Walker

I'd shiat my pants if I looked up and saw that.

They measured temperatures of -87° Celsius (-125° Fahrenheit) and these did not even figure in the additional windchill of 230 kph (143 mph) strong winds?

This sounds cold!

Imagine its so cold that the mercury in your thermometer has long since frozen solid and you are pelted by tiny ice crystals from hurricane strength winds....

I'd like to second TheNyquilKid's motion of pants-shiatting upon sight of said clouds.

Is there a higher-res version of that, Walker?

I keep expecting the Stay-Puft Man to come out of Walker's clouds.

There is a whole gallery of cloudscapes like the one Walker posted from the same photographer at:

here and here

I don't know if they actually get clouds like that in Nebraska or if the artist is using some sort of trickery like time-lapse or photoshopping to get this effect, but it sure does look freaky.

Nah, that's as big as it gets. You can see more photos of those kind of clouds here

No reason to shiat your pants over those clouds. They are called Mammatus clouds and are harmless. They are formed after a bad thunderstorm has passed.

Anyone on the global warming thread remember the 'weird cloud formations over Antarctica' I was talking about? Yeah, these are them.

/No debate here. Let's enjoy the awesomeness.

Not to be nit-picky, but if the nacreous cloud photo was taken this month, then it is forming at sun-rise, not sun-set (hooray for crazy long periods of light and darkness at the poles).

I've heard about nacreous clouds before from my cousin (in-law) who wintered-over in McMurdo. He kept a detailed blog of his stay and there was not a moment I didn't spend amongst those pages in complete and utter awe.

Everything about that place is beautiful-- deadly but beautiful. Isn't it always the most beautiful roses have the sharpest thorns?

/plans to go there someday
//cruise would be nice

The other thing about nacreous cloud - they're composed of NITRIC ACID. Seriously.

Was that a REUTERS photographer?
