the first big surprise of EMU’s experimental investigation was the discovery of mysterious strange radio rings (ORCs), which seem to be huge radio rings, nearly one million light-years in diameter, surrounding distant galaxies. A few weeks later, astronomers discovered two radio galaxies, about a billion light-years away. At the center of each galaxy is a supermassive black hole, and the jet of electrons is bent into strange shapes by the intergalactic wind. But where does the intergalactic wind come from? Why is it so tangled? What causes the emergence of radio current? Astronomers still don’t know the details of what’s happening here, and it may take more observation and modeling to understand

these things have never been seen before because they are so rare and weak. Astronomers still don’t know what they are, but they are working frantically to find out. Next to the studied Galaxy ic5063, astronomers found a huge radio galaxy. It is one of the largest known galaxies, and its existence has never been suspected. The Nova system also contains a supermassive black hole, ejecting nearly 5 million light-old electron jets. Askap is the only telescope in the world that can see this weak launch

most known radio emission sources are caused by supermassive black holes in quasars and active galaxies, which produce unusually bright signals.

Although ic5063 galaxy is a well studied galaxy, these plumes have never been seen before the EMU pilot survey

the EMU project has seen almost all spiral galaxies in the nearby universe, which previously could only be seen through optical and infrared telescopes. EMU can even track the nearest spiral arms. EMU will help astronomers understand the birth of new stars in these galaxies. The EMU team, composed of more than 400 scientists from more than 20 countries, has planned projects, developed technologies, written software, and worked with engineers building telescopes over the past 12 years. It was a long process, but astronomers finally saw the amazing data they had dreamed of for a long time
