The "water hole" is the name given to a radio frequency window that astronomers use to search for extraterrestrial communication. It is located between the hydrogen line (1420 MHz) and the hydroxyl line (1662-1670 MHz) frequencies, which are significant because they are abundant elements in the universe, making this range a likely candidate for interstellar communication.
