A starry sky made of more than 25,000 supermassive black holes

An international team of astronomers has produced the largest and sharpest map of the sky at ultra-low radio frequencies, using the Low Frequency Array (LOFAR) radio telescope. The map published in the journal Astronomy & Astrophysics reveals more than 25,000 active supermassive black holes in distant galaxies.

The LOFAR core is clearly visible on this Sentinel image from space, taken 11 February 2021. The HBA tiles have been blown clear of snow by the wind, which makes them contrast nicely against the snow on the ground.
