Whether extraterrestrial life exists, whether it is intelligent or not, is one of the great unknowns that human beings face. The answers, for the moment, are scarce. Maybe there is life in our own solar system or maybe not; We can’t say anything yet. But What if we look at the center of the Milky Way? Will we find life there? At the moment there are no positive results. In fact, a Article preliminary and without peer review concludes that in their search for signs of technology in the center of our galaxy they have found nothing. This is a somewhat disappointing result., but the research is very interesting. Therefore, let’s see what they say in this article that has not been, at least not yet, published in any scientific journal.
To begin with, it should be noted again that for the scientific community to take these results seriously, must pass the filter of scientific journals. And it is that to publish in them, other researchers have to review both the methodology and the results and conclusions of the study. Therefore, everything that we are going to tell you next must be taken with a grain of salt, at least until it is published in Publications of the Astronomical Society of Australia.
But back to the investigation. And it is that a team of Australian scientists, led by the Doctor Chenoa Tremblayhas concluded that they have not found technosignatures (signs of the use of technology) in the center of the Milky Way, our galaxy.
Search for intelligent extraterrestrial life, a challenge
The search for extraterrestrial life is a challenge. But the search for intelligent life seems to be even more so. Still, astrophysicist Tremblay has tried. This is his fourth research on the subject.as pointed out in the preliminary article.
To carry out the search for intelligent extraterrestrial life, the team has used the telescope Murchinson Widefield Array (MVA) for two nights. They obtained data from the center of the Milky Way, at the position of Sagittarius A*, for a total of seven hours. And with these scans, signs of the use of technology have been sought in the 144 planetary systems that we already know at a frequency of 155 MHz.
To know what kind of signals to look for, they looked at the technological development that has occurred on Earth. Because decided on “low frequency radio signalssuch as those used by FM radio”; since “they are a ubiquitous option for communications”, they indicate in the as yet unpublished article. “Many astrophysical processes give rise to low-frequency radio emissions”, so numerous telescopes of the current generation, such as M.W.A.are able to find these signals.
Research result
We have already said the result: there doesn’t seem to be anything. Or at least, according to this study that we must remember is preliminary. So intelligent extraterrestrial life may not exist in the center of the Milky Way. But we can also assume that there is life, but it is not yet developed enough to use technology.
In the article itself, in addition, the researchers point out that it may be necessary to make new sweeps in search of intelligent life with the new telescopes that come out. And it is that the tools with which we observe the sky also improve over time. In fact, they point out: “The continual enhancement of telescope capabilitieswhen combined with methodical observation campaigns, provides a means of explore the vast space of parameters within which signs of technologically capable life may be waiting to be found”.
In short, this preliminary article is, to say the least, curious. But we have to see its limitations. Perhaps there is no intelligent life, it will have to be verified; but that does not mean that there is extraterrestrial life. Because we did not suddenly appear as human beings, life made its way until we arrived. However, these results do not have to make us give up: let’s keep looking at the starsperhaps at some point we will confirm that we are not alone in the universe.
