In my opinion, the most appropriated level of Earth science that would be considered
the most interesting or catching would be Astronomy.
When you think of Astronomy-you think of space and the out world from our home.
Every day different space organizations such as NASA head into space trying to discover deeper
unknown places in Space. Astronomy intregrates the chemistry of radiation, the study of space, physics, scientific theorys, and atomic structure.
It also aids in discovering how our planet Earth was formed over time.

• Astronomy can be defined as two things:The scientific study of matter in outer space, especially the positions, dimensions, distribution, motion, composition, energy, and evolution of celestial bodies and phenomena; a system of knowledge or beliefs about celestial phenomena: the various astronomies of ancient civilizations.

Many people pay a fairly large sum just to aid in the space launches and control of landing areas.
It's a very big political aspect if you think of it economic wise.

Is it right to spend our money on Space?
Is it even worth it?

What really is out there in the unknown that's so worth while?
Astronomy is a very big topic in Earth science.
If you think about what could be out there.... other species.. new worlds.... other distant
Galaxys.... there's so much we have yet to discover. We use Astronomy to go to extremely far places-literally.
Astronomy is by far the best subject in Earth Science.
