The Extremely Far-Off Green Pea Galaxies

“Round or elliptical galaxies are huge and almost always reddish. Spiral galaxies are less huge but still large and almost always bluish. Galaxies that are small are almost never round and certainly not green. By July, 2008, the Zooites had found enough of these galaxies they were now calling Green Peas-their slogan, Give Peas a Chance!-that astronomers were getting seriously interested. So astronomers did what they always do with a new project, they gave it to a graduate student, this one named Carie.”
