An international team of more than 200 astronomers from 18 countries has published the first phase of a major new radio sky survey at unprecedented sensitivity using the Low Frequency Array (LOFAR) telescope. The survey reveals hundreds of thousands of previously undetected galaxies, shedding new light on many research areas including the physics of black holes and how clusters of galaxies evolve. A special issue of the scientific journal Astronomy & Astrophysics is dedicated to the first twenty-six research papers describing the survey and its first results.

The LOFAR radio telescope system receives in the range of 10 to 230 MegaHertz. This range hasn't gotten a great deal of attention in radio astronomy, of late. As the linked article, below, indicates, The LOFAR system will also be used to listen for radio transmissions from intelligent life in the universe. Given the unusual frequency range, who knows what they might find? We could have been listening in one frequency range, while SETI signals were streaming in, within another one.
