Quote:In 2005 the Hubble Space Telescope spotted unusually small galaxies densely packed with red stars in the distant, young universe. They were nicknamed “red nuggets,” not only because they are small and red but also their existence challenged current theories of galaxy formation, making them precious in astronomers’ eyes.

Since no “red nuggets” were seen nearby, astronomers wondered why they had disappeared over time. New research shows that they didn’t disappear completely. In fact, they were simply hidden within the data of previous surveys.
