Researchers have uncovered the existence of a dwarf “dark galaxy” lurking nearly 4 billion light-years away from Earth. The discovery was made when a team of researchers, including astronomers at the University of Illinois, using the Blue Waters supercomputer at the National Center for Supercomputing Applications, noticed subtle distortions in the image of gravitational lens SDP.81. The discovery paves the way to spot many more such objects, which could help astronomers address important questions on the true nature of dark matter.
