Intergalactic Joust: The Dance of Distant Galaxies

Astronomers have observed what can be likened to an interstellar joust, as two galaxies on a collision course were discovered. This cosmic dance was seen as it occurred 11.4 billion years ago in the early universe.

Utilizing two telescopes in Chile, researchers found one galaxy with a quasar at its heart disrupting star formation in the companion galaxy by emitting intense radiation, a novel occurrence never before documented.

The event highlights the gravitational interplay between galaxies, as noted by experts, eventually leading to their merger into a single larger entity. This study utilizes the ALMA and VLT telescopes to gain insights into these distant cosmic phenomena.
