Astronomers have inspected a mysterious isolated star cluster complex, SH2 in the galaxy NGC 1316 (also known as Fornax A). The results of their study, which were published Mar. 1 in a paper on arXiv.org, reveal important insights into the nature of this complex, providing crucial information about its origin.
Located some 62 million years away in the constellation Fornax, NGC 1316 is one of the brightest radio sources in the sky, classified as a lenticular radio galaxy. While the galaxy is dominated by old and intermediate-age stars, it shows signs of previous galaxy interactions. However, the only indicator of current star formation in this galaxy is HII region SH2.
