Active SETI. Active SETI, also known as messaging to extraterrestrial intelligence (METI), consists of sending signals into space in the hope that they will be picked up by an alien intelligence. SETI@home was off and running. The rest is history: SETI@home went online on May 17, 1999, and was an immediate and unprecedented hit. Within a few months more than a million people across the globe were processing work units on their personal computers, and within a year the number was approaching two million. SETI@home searches for possible evidence of radio transmissions from extraterrestrial intelligence using observational data from the Arecibo radio telescope and the Green Bank Telescope. The data is taken "piggyback" or "passively" while the telescope is used for other scientific programs. According to Prof. Tarter, in 2012 it costs around "$2 million per year to keep SETI research going at the SETI Institute" and approximately 10 times that to support "all kinds of SETI activity around the world".

https://en.wikipedia.org/wiki/Extraterrestrial

Extraterrestrial refers to any object or being beyond (extra-) the planet Earth (terrestrial). It is derived from the Latin words extra ("outside", "outwards") and terrestris ("earthly", "of or relating to the Earth").

The proper distance—the distance as would be measured at a specific time, including the present—between Earth and the edge of the observable universe is 46 billion light-years (14 billion parsecs), making the diameter of the observable universe about 93 billion light-years (28 billion parsecs).

The word extraterrestrial means "outside Earth". The first published use of extraterrestrial as a noun occurred in 1956, during the Golden Age of Science Fiction.

Thus, the range of frequencies from 1420 to 1720 MHz is called the Water Hole. It has been a popular frequency range for many SETI programs.

The Drake Equation is used to estimate the number of communicating civilizations in the cosmos, or more simply put, the odds of finding intelligent life in the universe.

https://en.wikipedia.org/wiki/Arecibo_message

The Arecibo message is a 1974 interstellar radio message carrying basic information about humanity and Earth sent to globular star cluster M13. It was meant as a demonstration of human technological achievement, rather than a real attempt to enter into a conversation with extraterrestrials.

SETI stands for the "search for extraterrestrial intelligence".
