Ancestors of Milky Way-Type Galaxies Found, Analyzed

Scientists have peered back into the earliest epochs of the universe and discovered the types of galaxies that form modern galaxies, including spiral types like our Milky Way.

The newfound galaxies represent some of the first to form in the universe–their light has traveled between 9 and 12 billion years to reach Earth, the bulk of the universe’s 13.7-billion-year existence.
