Repost from @The White House:

Take a look at the millions of galaxies that populate the patch of sky known as the COSMOS field, short for Cosmic Evolution Survey. A portion of the COSMOS field is seen here by @NASA's Spitzer Space Telescope. Even the smallest dots in this image are galaxies, some up to 12 billion light-years away.
The picture is a combination of infrared data from Spitzer (red) and visible-light data (blue and green) from Japan's Subaru telescope atop Mauna Kea in Hawaii. The brightest objects in the field are more than ten thousand times fainter than what you can see with the naked eye. #AstronomyNight
