It's an extended shutter photo. I wish TG2 could do that. Great find.

It has to be from space, if it's real.  The stars are showing - outer space.  Or what is it?

sweet, maybe tis just really clear there.

An extended shutter photo means that the camera shutter is held open for a longer amount of time, which allows more light to expose the film. This is why you see the stars and why the clouds and smoke look motion blurred.

It's referred to as 'long exposure': placing the camera on a support such as a tripod and leaving the shutter open for long time periods. You can actually see motion blur in the stars from the rotation of Earth, but only a little, meaning this exposure was probably in the ~1 minute range.

One of my favourite pictures is "A smoke angel from airplane flare" - dated 22-08-06

Thanks.  I knew this, but it looked like something was done from outer space, so I thought it has another meaning. 

lol
