Light Horror is a division in the Horror genre that categorizes horror movies from the early days of cinema, to the 1970s. The characteristics of such films, are their slow pace action, rare jump-scares, and scenes of contemporary life. They are mostly from easy to moderate to watch, and can be at times relaxing or very fun. One example would be the 70s TV series - Kolchak: Night Stalker.

The other side of the division, Heavy Horror, is on the other hand very fast paced, and doesn't give you any room to breathe. Heavy Horror features films which are very grim, dark, and show a whole slew of plots which basically have many flaws in them, and have no explainable ending. They are in essence, the film/comic/stand-alone drawing artist's attempt to create something which they think is so profound, when it's really just disturb-fucking-scary.

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.
