Extraterrestrial law refers to the legal frameworks and principles that govern activities related to outer space and celestial bodies. This includes treaties and agreements that regulate the use of space, such as the Outer Space Treaty of 1967, which establishes that space exploration should benefit all humanity and prohibits the placement of nuclear weapons in space. The field also addresses issues like the ownership of resources on other planets, the rights of potential extraterrestrial life, and the responsibilities of nations in space exploration. As humanity advances in space travel, the need for clear regulations becomes increasingly important to ensure peaceful and cooperative use of outer space.
