Zooming into the center: The left image shows the deepest view yet into the plasma jet of quasar 3C 273, allowing a closer look at how the jet is focused. This extends hundreds of thousands of light-years beyond the galaxy, as seen in the optical image on the right, taken by the Hubble Space Telescope. The researchers used radio images at different wavelengths and angular resolutions to measure the expansion of the entire jet. The radio interferometers used here are the Global Millimeter VLBI Array (GMVA), the Atacama Large Millimeter/submillimeter Array (ALMA), and the High Sensitivity Array (HSA). © Hiroki Okino and Kazunori Akiyama; GMVA+ALMA and HSA
