The article does call it an "observed age" of 30 years later on, but it should have been clearer at the beginning.

- archgoon 16y agoIt's perfectly clear, even if they hadn't said 'observed age'. The entire point of the article is that we're witnessing the development of black hole, thirty years in. How far away it is and 'how long ago' doesn't affect this.
