It's happening near an American research station and worringly one scientist (from the Goddard Flight centre) was quoted as saying
It's a clash of the titans; a radical and uncommon event
as if they were describing a bout between Ali and Foreman.
When the two ice giants hit each other, the impact will probably "dent their bumpers", according to Dr Binshadler.
Actually, it's more like he's commentating on a NASCAR event.
The B-15A iceberg is a 3,000 sq km behemoth that has a history of causing trouble. It is the largest fragment of a much larger iceberg that broke off from the Ross Ice Shelf in 2000.
This year, it trapped sea ice in McMurdo Sound. The currents that normally break the ice into pieces and sweep it out into the Ross Sea have not been able to clean out the Sound.
So winter's thick ice remains intact - causing problems for Antarctic residents.
That means penguins have to swim greater distances to reach open waters and food.
As a result, there is a danger many chicks could starve, according to Antarctica New Zealand, the government organisation that oversees the country's research.
A barrell of laughs for all fans of monster trucks everywhere, but not exactly a giggle for the many penguins and other creatures living near the Ross Ice Shelf.
