What can turn an entire galaxy?

 PBC J233.9-2343 was sending out jet material on either side...and it's 40 times the size of the Milky Way.

Was.

Now those jets are pointed directly at us. (Don't worry, it's 657 million light years away and it's not going to shoot us with anything).

Scientists are now trying to work out what could have turned a giant galaxy. The lead theory, of course, is a collision with another galaxy.

This happened a long time ago over a long time, basically we know because we can see the old jets that pointed in a different direction.

Maybe Q did it for a prank?
