Jobs which they often perform are doing testing on the compostion of the ocean in particular areas, and the effects that the environment have on the organisms in it. In exobiology, oceanographers study deep sea hydrothermal vents and the environment surrounding them. Testing is done on the chemical composition of the water, to see if, and how, organisms are able to survive. Often, oceanographers work closely with marine biologists and chemists when conducting research. When the planets and their moons are being observed to determine if life might be possible on them, it is an astronomer who is looking through the telescope.
Astronomers search the skies for many things.
Some search for other solar systems, some look or comets and meteorites, and some are busy making observations in our own solar system. Astronomers in exobiology are currently looking at the moons of other planets in our solar system, such as Titan and Europa, to determine if life was ever possible on them. They do this by examining both the atmosphere and the surface to see if organic compounds and liquid water were ever able to exist. These are just some of the jobs which are a part of the field of exobiology. If you think you might be interested in any of these occupations, click on these organizations to find out more about them.
