Galaxies Similar to the Milky Way

This composite image shows examples of galaxies similar to our Milky Way at various stages of construction over a time span of 11 billion years.
The galaxies are arranged according to time. Those on the left reside nearby; those at far right existed when the cosmos was about 2 billion years old. The bluish glow from young stars dominates the color of the galaxies on the right. The galaxies at left are redder from the glow of older stellar populations.
Astronomers found the distant galaxies in two Hubble Space Telescope surveys: 3D-HST and the Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey, or CANDELS. The observations were made in visible and near-infrared light by Hubble's Wide Field Camera 3 and Advanced Camera for Surveys. The nearby galaxies were taken from the Sloan Digital Sky Survey.
This image traces Milky Way-like galaxies over most of cosmic history, revealing how they evolve over time. Hubble's sharp vision resolved the galaxies' shapes, showing that their bulges and disks grew simultaneously.

Artist's Illustration of the Present and Early Milky Way
What a difference 11 billion years makes, as can be seen in these two comparative views of our Milky Way galaxy. The top view shows how our galaxy looks today; the bottom view, how it appeared in the remote past. This photo illustration is based on a Hubble Space Telescope...
