Hubble Reveals Universe's Oldest Galaxies
The new Frontier Fields images show 13-billion-year-old stars.
Hubble Space Telescope astronomers Tuesday released views of the oldest galaxies yet seen, about 13.2 billion years old. They offer intriguing glimpses of the chaotic birth of the first stars.
The images are the first in a series called Frontier Fields.
Explaining the earliest stars would answer astronomers' questions about how galaxies such as our own Milky Way arose and how stars such as our sun came to reside within a galaxy.
The universe is about 13.7 billion years old. Since 1995, the Hubble Space Telescope has provided astronomers with glimpses of galaxies ever closer in age to the early days of the cosmos. Hubble started with a Deep Field image produced by focusing toward the Big Dipper for 43
