Astronomers have discovered the ruins of an ancient star cluster in the outer fringes of the Milky Way. This stellar stream, known as C-19, extends across a large area of the night sky, approximately 30 times the width of the full Moon. The stars in the stream have a uniquely low proportion of heavy elements — lower than any other stellar system in the Milky Way or its surroundings. This discovery was made using telescopes on the ground and in space, including the international Gemini Observatory, a Program of NSF’s NOIRLab.
