WTF? "16 story tall black objects observed on Comet Hartley 2

After about 3.2 billion miles (5.1 billion kilometers) of deep space travel, several discoveries awaited the EPOXI mission's project and science teams. On Nov. 4, 2010, the mission spacecraft flew past a weird little comet called Hartley 2. A strane mission discovery is that on the knobby ends of Hartley 2, particularly the smaller end, the surface terrain is dotted with block-like, shiny objects, some as big as one block long and 16 stories tall. These objects appear to be two to three times more reflective than the surface average.
