The naturally weighted 1.6-GHz VLBI image of J1427+3312 at the frequency of 1.6 GHz (18 cm wavelength). The positive contour levels increase by a factor of v2. The first contours are drawn at -50 and 50 µJy/beam (3 sigma RMS noise). The peak brightness is 460 µJy/beam. Image: JIVE.

An international group of radio astronomers has found an unexpected morphology in the most distant radio quasar ever. This was done using the world's most sensitive network of radio telescopes called the European VLBI Network (EVN). The results of their discovery are published in the Astronomy and Astrophysics journal on 5 June.
