Today at 2 pm EST, AGU is holding a press conference titled “Penguins! From space” at Fall Meeting 2018. New research will be discussed about how studying satellite images of penguin poop, or guano, in west Antarctica can give scientists an idea of how penguin diets changed over decades or centuries.

To help you get a picture of the penguin research, check out this beautiful comic, created by JoAnna Wendel.
