Fornax A galaxy. Combined optical (white) and radio (orange) image of the galaxy Fornax A (NGC 1316,centre). The smaller galaxy NGC 1317 is above it. These galaxies are members of the Fornax cluster,a gravitationally linked group of 18 galaxies which lies around 70 million light years from Earth in the constellation Fornax. Fornax A is a powerful source of radio waves (orange). These radio emissions are powered by a massive black hole at the galaxy's centre.
