Here are 6 of the coolest jobs that are sure to generate alot of questions at a party. Please note that I did not create the content for this particular section. I also give the source of the information so you can look into it,  get a degree in one of those fields and change reality forever!

Galactic Archaeologist
Galactic Archaeology is concerned with the search for the most metal-poor and hence oldest stars of the Galaxy, and the determination of their chemical abundance patterns.
These stars are important tools for studying, e.g., the formation and chemical evolution of the Galaxy, the properties (e.g., mass, rotation) of the first generation of massive stars which exploded as type II supernovae and nucleosynthesis processes that occurred in them.

Exobiologist (or Astrobiologist)
The branch of biology that deals with the search for extraterrestrial life and the effects of extraterrestrial surroundings on living organisms. Also called astrobiology, space biology.
http://www.thefreedictionary.com/Exobiologist

The Exobiology Branch conducts research in Exobiology seeking to increase our knowledge of the origin, evolution, and distribution of life in the universe. Answers are sought to questions such as: To what extent did chemical evolution occur in the primitive bodies of the solar system? How did life originate on the Earth, and what role did minerals play? What evidence exists regarding the early interplay between biological and environmental evolution?

What do molecular fossils tell us about early microbial evolution? How can the study of contemporary microbes or geochemical samples inform us of past events? The work of the staff in this Branch also provides the conceptual basis and measurement criteria for future spacecraft missions to other solar system bodies such as Mars, Titan, and comets, in search of answers to such fundamental questions in non-terrestrial settings.

Exopsychologist
The field of Astropsychology or Exopsychology is the field of study concerned with how intelligent extra-terrestrial beings operate, including their behavior, mental processes, and pathologies and is directly related to the more established and recognized field of space science known as Astrobiology or Exobiology

Terraformer
The terraforming (literally, “Earth-shaping”) of a planet, moon, or other body is the hypothetical process of deliberately modifying its atmosphere, temperature, surface topography or ecology to be similar to those of Earth to make it habitable by humans.
The term is sometimes used more generally as a synonym for planetary engineering. The concept of terraforming developed from both science fiction and actual science. The term was probably invented by Jack Williamson in a science-fiction story (“Collision Orbit”) published during 1942 in Astounding Science Fiction,[1] but the actual concept pre-dates this work.

Plastinator
Plastination is a technique used in anatomy to preserve bodies or body parts. The water and fat are replaced by certain plastics, yielding specimens that can be touched, do not smell or decay, and even retain most microscopic properties of the original sample. The 5 steps of plastination are:

• Fixation
• Dehydration
• Forced impregnation
• Hardening
• Posing

Cryptozoologist
Cryptozoology (from Greek κρυπτός, kruptos, “hidden” + zoology; literally, “study of hidden animals”) is the study of and search for animals which fall outside of contemporary zoological catalogs. It consists of two primary fields of research:

• The search for living examples of animals taxonomically identified through fossil records, but which are believed to be extinct.

• The search for animals that fall outside of taxonomic records due to a lack of empirical evidence, but for which anecdotal evidence exists in the form of myths, legends, or undocumented sightings.

Those involved in cryptozoological study are known as cryptozoologists; the animals that they study are often referred to as “cryptids”, a term coined by John Wall in 1983.

Cryptozoology has seen very little attention from the mainstream scientific community because it does not follow the scientific method in attempts to support its claims.
