Astronomers have made a groundbreaking discovery of a colossal bridge of neutral hydrogen gas linking two dwarf galaxies. Scientists at The University of Western Australia’s node of the International Centre for Radio Astronomy Research (ICRAR) have made a remarkable discovery: a massive structure stretching about 185,000 light-years between two galaxies, NGC 4532 and DDO 137, located some 53 million light-years from Earth.
According to a study published in the Monthly Notices of the Royal Astronomical Society, the team also detected a huge tail of gas extending another 1.6 million light-years beyond the bridge, making it the largest feature of its kind ever recorded.
Lead researcher Professor Lister Staveley-Smith from ICRAR UWA explained that the finding provides an important n...
