Tidal debris detected in a nearby galaxy group

Using the MeerKAT telescope, an international team of astronomers has identified wide-spread tidal debris in a nearby galaxy group known as NGC 7232. The newly found structure is composed of cold neutral atomic hydrogen and extends over 450,000 light years. The finding is reported in a paper published May 21 on arXiv.org.

The ground that was beneath this ice is also shifting and rising as these glaciers disappear. Geologists have discovered a link between recent ice mass loss, rapid rock uplift and a gap between tectonic plates that underlie Patagonia. from Phys.org - latest science and technology news stories https://ift.tt/j1h2ds5
