Very young stars, known as ‘pre-T-Tauri stars’ (PTTS) or ‘young stellar objects’ (YSO), tend to be surrounded by elongated outflow regions involving ‘Herbig-Haro objects’ (HH). Such ‘bipolar flows’ (BF) are reminiscent of the extragalactic radio sources for which a consensus has formed in 1986 that their jets consist of extremely relativistic pair plasma, of typical Lorentz factor 104±1, generated by an ‘active galactic nucleus’ (AGN); [refs 6,7]. Here I collect new circumstantial evidence for the relativistic nature of BFs.
