NASA has announced that they have confirmation that Saturn’s moon Enceladus has a food source that could support potential microbial lifeforms. This crucial ingredient accompanies Enceladus’ grocery list of elements needed to support life: carbon, hydrogen, nitrogen, oxygen, organic molecules, and of course, liquid water.

"Almost all of the conditions that astrobiologists have identified for habitability are present on Enceladus: water, organics, and a chemical energy source," explains Hunter Waite, from the Southwest Research Institute. "The only things that are left on the checklist are phosphorus or sulfur."

These high-flying menageries were sent aloft to study the effects of travel into space on biological organisms, as no-one at the time knew what would happen to a human being if they were sent to that high an altitude.
