Interacting galaxies produce eye-shaped “tsunami” of stars

Astronomers using the Atacama Large Millimetre/submillimetre Array (ALMA) have discovered a tsunami of stars and gas that is crashing midway through the disc of a spiral galaxy known as IC 2163. This colossal wave of material — which was triggered when IC 2163 recently sideswiped another spiral galaxy dubbed NGC 2207 — produced dazzling arcs of intense star formation that resemble a pair of eyelids.

Buried in the heart of a giant

This is a young open cluster of stars known as NGC 2367, an infant stellar grouping that lies at the centre of an immense and ancient structure on the margins of the Milky Way, captured by the Wide Field Imager (WFI) camera on the MPG/ESO 2.2-metre telescope at ESO’s La Silla Observatory in Chile.
