Story summary

Scientists discovered a unique Einstein Cross with five light points around the galaxy HerS-3, challenging existing astronomical models.
The fifth image suggests a massive dark matter halo, as visible matter alone cannot explain it.
Data from the Northern Extended Millimeter Array (NOEMA) and Atacama Large Millimeter/submillimeter Array (ALMA) confirmed this anomaly.
Advanced modeling indicates that only a dark matter halo can create the observed lensing pattern.
This discovery improves understanding of dark matter's influence on galaxy formation and evolution.
