  The family links between radio galaxies and microquasars have been strongly
strengthened thanks to a new common phenomenon: the presence of extended winged
features. The first detection of such structures in a Galactic microquasar,
recently reported in Nature Communications (http://rdcu.be/zgX8), widens the
already known analogy between both kinds of outflow sources (Mart\'i et al.
2017). This observational result also has potential implications affecting the
black hole merger scenarios that contribute to the gravitational wave
background.
