An early universe radio jet spanning an astonishing 200,000 light years has been discovered by the International Gemini ...

Abell 2255 is a cluster containing between 300 and 500 constituent galaxies, many of which are merging. It's located around 800 million light-years from Earth and spans around 16.3 million light-years ...

Our LOFAR survey only covered 15 percent of the sky. And most of these giant jets are likely difficult to spot, so we believe there are many more of these behemoths out there.” ...

The jet is known as Quasar J1601+3102, and it was first spotted by astronomers using the Low Frequency Array (LOFAR). Researchers estimate that the jet spans nearly 200,000 light-years, more than ...
