Hubble telescope captures images of the oldest galaxies
By Michael J.W. Stickings
This is just awesome:
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.
This is galaxy cluster Abell 2744. It's "the deepest image ever made of any cluster galaxy":
