This spooky mug won't be staring off into space forever. The ring structure that outlines the face will last for only about 100 million years, while the merging of the two galaxies is expected to take about 1 billion to 2 billion years, NASA officials said in a statement.
While galaxy collisions are quite common in the universe, head-on collisions like this one are relatively rare, and the particularly violent nature of this type of collision gives rise to the peculiar ring shape. "The galaxies have to collide at just the right orientation to create the ring," NASA officials said. "The crash pulled and stretched the galaxies' disks of gas, dust, and stars outward. This action formed the ring of intense star formation that shapes the nose and face."
