International astronomy team reveal images of star-forming galaxies

An international team of astronomers have used ultra-sensitive radio images to reveal thousands of star-forming galaxies in the early universe. The scientists compiled the images using the International Low Frequency Array (LOFAR) telescope, a trans-European network of radio antennas. It works by combining the signals from more than 70,000 antenna, located in stations across the Netherlands and in partner European countries including the UK. By observing the same regions of sky repeatedly and combining the data to make a single very-long exposure image, the team detected the faint radio glow of stars exploding as supernovae, in tens of thousands of galaxies out to the most distant parts of the universe.
