Actually, the common standard is that whenever distances are reported in light years, they are actually lookback times and not distances at all. There is no difference in our galaxy, but at much larger distances where the metric expansion of the universe comes into play, it is almost always lookback times that are reported in the popular press, rarely comoving distances (even though "light year" is a distance, not a time). If they don't say "comoving distance," and they generally don't, they mean lookback time! Apparently a decision was made long ago that this distinction would only confuse people, so ingrained are we in the idea of a static universe. Here's a random example, at https://www.eso.org/public/usa/news/eso9304/ : " This corresponds to a look-back time of 83% of the age of the Universe, i.e. we see them as they were when the Universe was less than one-fifth as old as it is now. Assuming the age of the Universe to be 20,000 million years, the distance to this quasar would be about 16,000 million light-years." Don't ask me why they also decided to "dumb down" the numbers themselves! It's pretty awful what article writers think the public can understand.
