|This galaxy is having a bad millennium.
In fact, the past 100 million years haven't been so good,
and probably the next billion or so will be quite tumultuous.
Visible on the upper left, NGC 4038 used to be a normal spiral galaxy, minding its own business, until NGC 4039, toward its right,
crashed into it.
The evolving wreckage, known famously as
the Antennae, is pictured above.

Such collisions are not unusual, and even our own
Milky Way Galaxy
has undergone several in the past and is
predicted to collide
with our neighboring
Andromeda Galaxy in a few billion years.
