What is a proto-galaxy?
AstronomyGalaxy Formation
Quick Answer
A proto-galaxy is an early stage in galaxy formation, before a galaxy has fully assembled into its final shape. These objects are found in the young Universe.
The Full Story
Proto-galaxies are assembling systems of gas, stars, and dark matter seen at very high redshifts, when the Universe was young. They are important because they show how the first large galaxies grew from smaller clumps after the cosmic dark ages. Observations with powerful telescopes, including the Hubble and James Webb Space Telescopes, have revealed many extremely distant candidates. Studying proto-galaxies helps astronomers understand how star formation, mergers, and black hole growth began.
