Faster than Light Motion?

Astronomers have been observing faster than light phenomena for a long
time now.

``We see almost a dozen clouds which appear to be moving out from the
galaxy's center at between four and six times the speed of light.
These are all located in a narrow jet of gas streaming out from the
region of the black hole at the galaxy's center," said Dr. John
Biretta
of the Space Telescope Science Institute.

But then they have to always try to explain them away.

``We believe this apparent speed translates into an actual velocity
just slightly below that of light
itself." Biretta

What gives? Are things really moving faster than light?
