How strange looking. Is that for real? Or has it been digitally altered?

It’s for real - it’s NASA’s “Astronomy Photo of the Day,” apparently capturing a pretty rare phenomenon. As to whether the photographer may have touched it up a little, I can’t say.

If I recall—this is caused by a down burst. If conditions were right, and this got kicked up on one end—you would have one hell of a tornado, or in this case—a waterspout.

I saw one of these one morning at a music festival after a night of terrible stormage. It passed right over camp, and everyone just stood and stared.

Seriously?  That can’t be for real.  I’d have to see video of it ... or else I suspect it’s touched up.

I could be naive, but I don’t think NASA’s in the habit of posting fictional weather formations on their website.

For those skeptics out there, this is indeed a real cloud phenomenon. No PhotoShop needed.

The occurrence in Northern Australia is called the Morning Glory.

Have a look at it in all its glory (no pun intended) at

Amazing stuff!
