In a study published in The Astrophysical Journal, researchers reveal a markedly different ecosystem from the smaller number of satellite galaxies that circle our Milky Way in the nearby Andromeda galaxy.

When researchers glimpsed the first images and data from the James Webb Space Telescope, humanity’s largest and most powerful space telescope, they noticed something peculiar. A large number of bright galaxies deep in the universe formed during a period called “Cosmic Dawn." New research published in The Astrophysical Journal Letters shows that a theoretical model produced roughly five years ago predicted these very observations and credits them to bursty star formation.
