Take a Splash Into the Cosmos
Millions of galaxies populate the patch of sky known as the COSMOS field, short for Cosmic Evolution Survey, a portion of which is shown here. Even the smallest dots in this image are galaxies, some up to 12 billion light-years away. The square region in the center of bright objects is where the telescope was blinded by bright light.andnbsp;However, even these brightest objects in the field are more than ten thousand times fainter than what you can see with the naked eye.
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.andnbsp;These data were taken as part of the SPLASH (Spitzer large area survey with Hyper-Suprime-Cam) project.
