By fitting theoretical and observed radio maps, it was possible to find the scale of the jet (OJ 287) that depends on the average projected jet speed in the sky. This offers an important view into the internal dynamics of the secondary jet. Last year, the Dark Energy Spectroscopic Instrument's map of the Universe suggested that dark energy may not be constant. Last month, The Dark Energy Survey released its final results. Did they confirm the DESI measurement? Why are comple
