Galaxies carry the imprints of past encounters. When they pass near one another or collide, gravity pulls their stars into long tails, thin streams, and faint shells – features that preserve the history of these dramatic events. Thanks to deep, high-resolution images from the Euclid space telescope, an ESA (European Space Agency) mission with critical contributions from NASA, we can now see these delicate structures more clearly than ever before in unprecedented numbers.
