Galaxies Battle in ‘Cosmic Joust’ Witnessed by Astronomers for the First Time
- Astronomers observed two distant galaxies 11 billion light-years away engaged in a 'cosmic joust' as they merge in the early universe.
- This event occurred because quasars, the bright cores powered by supermassive black holes, emit strong radiation that often outshines host galaxies and can impact nearby galactic gas.
- Researchers used data from ESO’s Very Large Telescope and ALMA telescopes in Chile over nearly four years to distinctly observe the merging galaxies and the quasar's radiation effects.
- Study coauthor Sergei Balashev noted that this marks a novel observation of how radiation from a quasar influences the molecular gas within a neighboring galaxy, shedding light on its impact on star-forming regions.
- The findings offer a rare insight into galaxy evolution and quasar influence during a cosmic epoch when galaxy mergers and star formation were more common, though it remains unclear if such jousts are typical.

‘Violent’ galactic merger captured by ESO telescopes
Future Space The Very Large Telescope (VLT) and the Atacama Large Millimeter/submillimeter Array (ALMA) has captured a "violent cosmic collision in which one galaxy pierces another with intense radiation," according to the European Southern Observatory (ESO).

Telescope Capture Galaxies in Comparison with Space
Astronomers made a fascinating discovery by observing two galaxies involved in a real “duol” in deep space. Using data from terrestrial telescopes collected for almost four years, researchers witnessed these distant galaxies at an impressive speed of more than 1.8 million kilometers per hour. During this process, one of the... The post Telescope captures galaxies in comparison with the area appeared first on The Antagnonist.
