Monster Galaxy Observed at Dawn of the Universe –“Ancestor of the Huge Elliptical Objects That Exist Today”

Astronomers obtained the most detailed anatomy chart of a monster galaxy located 12.4 billion light-years away. Using the Atacama Large Millimeter/submillimeter Array (ALMA), the team revealed that the molecular clouds in the galaxy are highly unstable, which leads to runaway star formation. Monster galaxies are thought to be the ancestors of the huge elliptical galaxies (image below) in today’s Universe, therefore these findings pave the way to understand the formation and evolution of such galaxies.
