Where Do the Biggest Galaxies Come From?

Scientists have studied ancient, dense elliptical galaxies that defy typical formation models. These galaxies, more massive than any known, puzzled researchers until the discovery of submillimeter galaxies. These dusty, star-forming regions, invisible in visible light, were found using submillimeter radiation. They form stars rapidly, suggesting they evolve into massive ellipticals. This discovery helps explain the origins of the universe's largest galaxies, highlighting the role of technology in uncovering cosmic mysteries.
