Ignore the hype, just look at the images, and note:
The team used the Low Frequency Array (LOFAR) telescope in the Netherlands to pick up traces — or “jets” — of ancient radiation produced when galaxies merge. These jets, previously undetected, can extend over millions of light years.
The map created by the LOFAR observations, part of which was published in the journal Astronomy & Astrophysics, contains data equivalent to ten million DVDs yet charts just two per cent of the sky.
The LOFAR telescope is made up of a Europe-wide network of radio antenna across seven countries, forming the equivalent of a 1,300-kilometre diameter satellite dish.
