The Quiz: Which of Jupiter’s moons has been suspected of harboring life?
Europa
Callisto
Dia
Thebe
After the first NASA flyovers of Europa in the late 1970s, the moon made headlines with an exciting new discovery: possible liquid water. After decades of additional research, scientists now hypothesize that this moon has the three main requirements for life as we know it: liquid water, an energy source, and chemical elements for the building blocks of life. This makes Europa one of the most likely places in our solar system to support life.
The correct answer to this quiz is Europa.
