Physicists identify the engine powering black hole energy beams

>> “The black hole in M87 is about the size of our solar system,” Issaoun said, yet it produces a 5,000-light-year-long current of white-hot plasma

Do both jets put together have a length of 5000 light years or does each of the two jets have a length of 5000 light years making a total lenght of 10000 light years?

Can someone please clarify. I have had this question for a ling time and it is eating me up.

Edit: grammar.

That's just one of the jets. In fact, I think only one side is observable as it pointed close to our direction, making the other side very difficult to observe.

Yes. The forward jet is already faint despite being enhanced because it's pointed towards us. We can't see the backward one until it's way way outside the galaxy.
