Overview of the ASKAP 944 MHz Sculptor field. Overlaid are enlarged images of the 15 giant radio galaxies in the sample. Credit: arXiv (2025). DOI: 10.48550/arxiv.2504.07314 Using the Australian Square Kilometer Array Pathfinder (ASKAP), astronomers have discovered 15 new giant radio galaxies with physical sizes exceeding 3 million light years. The finding was reported in a research paper published April 9 on the arXiv preprint server. The so-called giant radio galaxies (GRGs) have an overall pr...
