“Baby Galaxy” Born 800 Million Years Ago

A look at the giant galaxy “HUDF-JD2” was revealed on September 27 by U.S. astronomers. Although HUDF-JD2 has a short history of 800 million years compared to our 13 billion, its mass is eight times larger. It is therefore known as the “Big Baby.” Also, it reverses the existing theory that stars gather to gradually evolve into a big galactic system.
