The safeguarding of Earth and other worlds from biological cross-contamination (i.e. billionaires with too much time on their hands).

Also known as “planetary protection.” Planetary protection / quarantine “reflects both the unknown nature of the space environment and the desire of the scientific community to preserve the pristine nature of celestial bodies until they can be studied in detail.”

There are two types of interplanetary contamination. Forward contamination is the transfer of viable organisms from Earth to another celestial body. Back contamination is the transfer of extraterrestrial organisms, if such exist, back to the Earth's biosphere.

An event or situation that is unpleasant or causes extreme distress.

Derived from Captain Kirk's famous yell of "Khaaaaaaaan!!!" in Star Trek II: The Wrath of Khan

The leading antagonist in the episode "Space Seed" of Star Trek: The Original Series. Spawned the second Star Trek movie, titled "The Wrath of Khan". Khan was the leader of the genetically engineered "super humans" created during the fictional Eugenics War (World War III), which occured in the late 20th century. Kirk's famous outburst in the movie, in which he screams, "KHAAAAAAAAN!" is still used today to express rage at a situation.

The name of a pose commonly used for profile pictures on social sites such as facebook. Typically the Khan is performed by a shirtless male often covered in some sort of lubricant where the male has one arm behind the head to accentuate the biceps.

Variations of 'The Khan' include

'The 2 handed (or Double) Khan' where both hands are placed behind the head. (useful in those situations where 1 hand just isn't enough) and the ever-popular 'Inverted Khan'.

Although , the name khan is prevalent almost worldwide, the true khan family are the descendents fo the Icursian tribe of ancient Egypt. Micheal Hart, one of the most famous eugenicists traced the Khans to be the true proto-hamitic or the Aryan peoples. Although the Khan families are predominantly caucasian throughout the Middle east and Europe, they also include a vast number of muslim families in places like India, China and south east asia. An interesting fact: Khan families in Europe and elsewhere have for long provided excellent athletes, musicians and actors in various countries.

A Khan is always ready for trouble. They tend to be naturally talented and often have (many) friends. They are charming and those around them feel cheerful. They are great at video games and eating cheese. They are (no doubt) able to handle pressure. Basically, (they) are perfect except for the fact that they can (sometimes) obliterate people with their sheer greatness.
