'Inside-out' galaxy growth observed in the early universe

Astronomers using the James Webb Space Telescope have observed the earliest-ever detection of inside-out galactic growth in a galaxy 700 million years after the Big Bang. This galaxy, 100 times smaller than the Milky Way, has a dense core but is growing rapidly in its outskirts. It doubles its stellar mass in the outer regions every 10 million years, compared to the Milky Way's 10 billion years. The discovery provides new insights into early galaxy formation and evolution, allowing scientists to study processes previously only theorized through models.
