From yesterday's Daily Mail:

The effect is known as the 'Prandtl-Glauert singularity' and is caused by pressure differences around the aircraft. A sudden drop in pressure associated with high speed allows water vapour, which is normally invisible, to condense as fog.
These condensation clouds are frequently seen during Space Shuttle launches but their precise nature is still under debate.
The plane was pictured looking up from the deck of an aircraft carrier during Alaska’s single largest military training exercise.
