"Euclid Telescope Unveils Trillions of Orphan Stars and Galactic Wonders"

The Euclid space telescope has discovered 1.5 trillion orphan stars in the Perseus galaxy cluster, emitting faint intracluster light. These stars, originating from disrupted smaller galaxies, are spread up to 2 million light-years from the cluster's center. The findings suggest a recent merger in the cluster, causing gravitational disturbances. This discovery, part of Euclid's early observations, enhances understanding of galaxy evolution and dark matter mapping.
