Two of the world's biggest icebergs

One of the world's biggest icebergs recently collided with a giant glacier to form another massive iceberg.

The above image was composed by the European Space Agency.  ESA (h/t Antarcticana) explains:

This animation, made up of eight Envisat radar images, shows the 97-km long B-9B iceberg (right) ramming into the Mertz Glacier Tongue in Eastern Antarctica in early February 2010. The collision caused a chunk of the glacier’s tongue to snap off, giving birth to another iceberg nearly as large as B-9B. The new iceberg, named C-28, is roughly 78-km long and 39-km wide, with a surface area of 2500 sq km (the size of Luxembourg).
