A team of astronomers led by Michael Koss of Eureka Scientific Inc. has observed several pairs of galaxies in the final stages of merging together into single, larger galaxies. Peering through thick walls of gas and dust surrounding the merging galaxies’ cores, the team captured pairs of supermassive black holes — each of which once [...]... SCI-NEWS.COM · 2 months
