Phys.org isn’t a popsci publication, it’s a press release aggregator for scientific publications. This is a press release from the NRAO. https://public.nrao.edu/news/2018-alma-luminous-streamers/ https://public.nrao.edu/news/2018-alma-luminous-streamers/ Also in this case luminosity is exactly the correct term as it describes the intrinsic brightness (how much light is emitted in a given unit of time) of an object not its appearent brightess (how bright it is to the observer) which is affected by distance and other factors.
