They build on discoveries made by other scientists and apply these theories and principles to their own scientific study. 47 Chapter 6 Becoming an Astrobiologist TRAINING FOR ASTROBIOLOGISTS If you’re interested in a career in astrobiology, you should take as many math and science classes as you can. This will give you a strong background for courses in biology, physics, and advanced mathematics in college. These are the foundations of astrobiology training. Scientists use the principles of math, physics, and chemistry to understand life in the universe.

The orbit of a planet says a lot about whether it could support life. For example, the mostly circular orbit of the Earth keeps it in a stable habitable zone (scientists sometimes refer to this as the “Goldilocks zone”—not too hot, not too cold, but just right) where the warmth of the sun allows life to thrive. If a planet’s orbit is too elliptical, distances can be too extreme at some points—either too close or too far away from the star that gives the planet warmth. Earth-like orbits are also of interest to astrobiologists because the stable temperatures would allow any water on the planet to remain there and not evaporate.
