ALIEN NEWS BOADCAST CRACK
A skilled alien equivalent of SETI might crack FM Radio or maybe conventional analogue TV, but the stuff coming out of a mobile phone base station doesn't even have an obvious carrier wave frequency. One thing's for sure though, we humans are using fewer huge and ultra powerful transmitters as time goes on, and using more and more much smaller devices with much more complex signals.
Accounting for radio bursts from sources such as rapidly rotating black holes, pulsars, neutron stars, quasars, and magnetars, etc, etc and that's not even including collisions or other cataclysmic events like super/hypernovas, there's simply too much background noise and radiation for exosolar civilizations to make themselves heard. note Ignoring the fact that space is both vast and far nosier than we could ever be. Another scientific theory is that they've developed a different form of communication that doesn't depend on radio broadcasts, and all of their surviving transmissions from when they did have already passed us by. note The infamous "Wow! signal" is an example of this although it demonstrates all the characteristics of an interstellar signal, no one is sure whether it was natural or artificial. Directed radio signals (like radar signals) can be possibly received thousands of light years away but can be detected in a far smaller area and may not even be recognized as sign of extra-terrestrial life.
ALIEN NEWS BOADCAST TV
First of all, non-directional broadcast signals (like TV and radio signals) cannot be received beyond a fraction of a light year even by much more powerful telescopes than the ones available, so it shouldn't be that surprising that we have not been receiving any of their transmissions, even if they have radio technology (or maybe they all read books on their planet).
However, no response has been picked up so far.Ī new plan is now being considered to send another signal into deep space with new information that includes simple principles for communication, basic mathematical concepts, physics formulas, constituents of DNA along with information about humans, the Earth, and a return address if someone wants to revert.There are some major technical problems with this concept, but most writers will ignore them. The astronomer identified an object in deep space to be the potential source of the wow signal, the sun-like star 2MASS 19281982-2640123, which is too dim to image with current technology, an extragalactic source, or any other origin.Įarth, too, had broadcast a radio message using the powerful Arecibo telescope in Puerto Rico containing information about the basic chemicals of life, the structure of DNA, Earth’s place in our solar system, and a stick figure of a human. An extraterrestrial civilization could have opted to behave in a similar manner," Caballero said in the paper. "If we analyse the history of (the few) radio signals that humanity have sent to several targets in the hope of contacting a civilization, none of those transmissions had a long duration or were repeatedly sent for a long time.
The search for the source has taken over 45 years as it never repeated and a similar signal was never detected. The research published in the International Journal of Astrobiology states that a total of 66 G and K-type stars were sampled to find out the source of the alien signal, but only one of them is identified as a potential Sun-like star considering the available information.Īstronomer Alberto Caballero, who led the research, has identified 2MASS 19281982-2640123 to be the ideal target to conduct observations in the search for techno-signatures of the signal. Reportedly, the Search for Extraterrestrial Intelligence (SETI), which has been searching the dark trenches of the universe for intelligent lifeforms, continues to study the signal. Years later, researchers have identified the source of the radio signal that Ehman had dubbed 'WOW" signal to a sun-like star in the constellation Sagittarius nearly 1800 light-years away from Earth. Upon seeing the printout of the unique signal, astronomer Jerry Ehman circled the strange frequency and scribbled 'wow', giving it the mystic name.
