Perseus cluster

The first scientific pictures from the Euclid satellite mission have revealed more than 1,500 billion orphan stars scattered throughout the Perseus cluster of galaxies.

The Perseus cluster, located 240 million light-years away from Earth, is one of the Universe's most massive structures, boasting thousands of galaxies.

Dr Jesse Golden-Marx, a Nottingham astronomer involved in the study, commented, "This novel observation suggests that the massive Perseus cluster may have recently undergone a merger with another group of galaxies. This recent merger could have induced a gravitational disturbance, causing either the most massive galaxy or the orphan stars to deviate from their expected orbits, thus resulting in the observed misalignment."

There are more than 100,000 galaxies in the telescope’s first snapshot of the Perseus cluster, including extremely faint ones that were never seen before.

The Perseus Cluster is one of the most massive structures in the Universe.
