New sky survey reveals hundreds of thousands of galaxies

The radio signals of almost 300,000 sources have finally reached Earth, and most of them are previously unknown galaxies from the distant universe. More than 200 astronomers in 18 countries created a radio sky survey using the Low Frequency Array telescope, known as LOFAR. The first phase of this major survey was published this week,…MORE
