There is an alien message from our planet of Mars and Venus, the Earth, from the Milky Way of the billions of galaxies in the front, the Orion arm from the 3 spirals, the star system of the Sun, about 25,000 light years away from the center of the galaxy, there is an alien message: **"Morning-sheriffs are alive."** In 1977, NASA's Voyager spacecraft sent to the alien message that Turkey sends messages containing a record of the world's languages that. What about this message? Are there really any creatures out of the world (like human beings)? Do they have a more advanced civilization than we do? ***In this article, we will talk about the possibility of life outside the Earth, if there is a scabious universe, a mysterious galaxy, a scabby strand of our Earth, who thinks that it is not scabious, and if so, how we look for it. As you can see in the top cover picture, if there is indeed a place on the side of the universe that can be considered very ordinary compared to its own galaxy, why does life in the rest of the universe cause it to happen ?! This question is also included in Stephen W. Hawking's expert on the subject of most scientists' response: YES, may be aliens ** First of all, calls to Earthly Smart Living begin with a very simple assumption, if there is a civilization / planet that produces and uses science and technology, which are the symbols of civilization, we carry Radio Waves out of the planet like our Earth. Because it is the key point of our civilization: to actually create and communicate electromagnetic waves; television, telephone, internet, satellites, space telescopes, particle accelerators, etc. these are the best examples. In Figure 2 you can see how the planet of the human race, actually a "developed" race, looks from the outside - if it is - by the **"aliens".** At its simplest, we are controlling these satellites with Radio waves and we are flooding the radio waves out of our planet. Let's not forget that the atmosphere of the Earth can pass radio waves; so even if we did not have our satellites, some of the TV, radio, and telephone broadcasts would still flee the world. ![image](https://img.esteem.ws/bnmauzcckt.jpg) *The European Space Agency (ESA) considers the orbits of our earth, or in other words, our technological garbage Of course, this photo should be added to 104 satellites launched by India in February 2017.* ## [İmage Source](https://fizikist.com)

Radio astronomy began in the 1930's when an antenna for Bell Labs' wireless communication accidentally recorded signal for the first time in a long distance. It was understood that the first recorded radio waves came from the center of the Milky Way Galaxy. Later, the radio telescopes would be "the sight of the whole universe", and the instrument of the Universal Continuous Microwave, which is the proof of the Big Bang, is the instrument (microwave, part of the small wave of radio waves) that makes sense of how the universe exists . Of course, did not the possible living forms of radio frequency bring us a little prejudice to be the way to communicate with us ?! Jocelyn Bell explained a passing headline during a presentation: "In my doctoral years, I was examining a datum taken with a radio telescope and there was a repetitive signal in about one second." Put yourself in Jocely's place, please, about one second, If it comes from the depths of space, what could it be? Did not you go from somewhere on your mind to **"trying to explain something to the aliens?"** Of course, a repetitive signal at the moment was actually a neutron star completing the cycle in seconds and waving radio waves around it, and later discovered more. This data, which was first recorded by Jocelyn Bell in 1967, will then be used as a star (pulsar) in scientific writing and conclude with the Nobel Prize. ![image](https://img.esteem.ws/c9xxrk1po1.jpg) *A neutron star, or pulsar that rotates at a certain frequency and emits a cone-shaped radio wave jet. Of course, the telescope on Earth was thought to be a meaningful message for a moment as it was signaled at the frequency of rotation.* ## [İmage Source](https://fizikist.com)

**The "search for intelligent life", which started in the 1960s, continued in the '70s with' how to put ourselves in space and communicate with the Earth '. At least we could have been through the radio waves that humans know, make, control and perceive the easiest and therefore the best means of communication. But are we talking about radio waves between 3 kHz and 300 GHz, the widest range of the electromagnetic spectrum, and exactly which frequency should we focus on?*** The answer is simple, if the aliens know a little about us and life; They had to choose a frequency that the world was completely permeable and what it needed to start and last for life; the frequency of water! Yes, if we are communicating with our world, our password is obvious: water, or H + OH as in radio spectroscopy. Hydrogen (H) 21 cm and Hydroxyl (OH) are propagating in 18 centimeter radio waves, that is, by dividing the speed of light into these wave lengths (λ = c / f), the aliens must communicate with us in the 1666-1400 MHz frequency range. We call this water-hole in the frequency range and it is an easy spectrum to observe from the Earth because it has at least background noise (it is already selected for this reason). Did we find something exciting in this frequency range? Yes, his name is "wow! signal "(wow, signal!). It was a short-lived signal recorded by the Big Ear Observatory in 1977 at the frequency of the water void and lost its value due to the fact that it could not be recorded anymore - a signal from a statistical or systematic error. Radio telescopes are not only used to search for aliens. It is a device that is widely used in aeronautical and defense industries (and traffic fines), which we know as radio wave detectors, RADAR (Turkish Radiation Detection and Distance Measuring Instrument). So, giant radio telescopes are not only natural radio wave sources: galaxies, neutron stars, black holes and pulsars; ballistic rockets, their satellites, if any, aliens and their technological equipment. ## [All Article Source](https://fizikist.com)
