For 4 days the pulse is noticeable, a hiatus of three times as long follows. A mysterious space signal strikes the Earth every 16 days.
The question that comes to mind is really always the same: are we alone in the universe? The answers, at least the scientifically founded ones, have been disparate, but none of them has been, in some way, definitive.
There are no irrefutable traces of alien civilizations: for the rest, some scientists hypothesize life in space based on some photos taken by the NASA rover on Mars (specifically, it would be even extraterrestrial mushrooms). A well-known Harvard professor has also collected 2 million dollars for the project that will search for life on other planets. And what about Oumuamua, the mysterious and unpronounceable space object that several times has been compared to a UFO probe?
What are the galactic pulses FRBS and why we talk about it
To enrich this range of theories on extraterrestrials come some curious galactic signals, called Fast Radio Bursts (FRBS) that, scientists have observed, are repeated at intervals of time always equal. To be precise, they are very strong radio signals yet very short, observable at a distance of billions of light years. At the origin, is the hypothesis, there would be very powerful sources of energy. Among the FRBS, some are observed once and then never again, others on more than one occasion.
What is the space pulse that always returns the same
A team of researchers led by Inés Pastor-Marazuela, PhD at the Anton Pannekoek Institute of Astronomy at the University of Amsterdam has gone a step further, actually managing to capture the pulses in question at lower frequencies than those experienced so far: the new study has revealed a sequence that always repeats the same, based on an interval of 16 days. Specifically, the pulse propagates for a third of the time, immediately after comes a pause that lasts three times as long (12 days). This regularity is repeated again and again.
Some might think that behind the "mathematics" of the signal there is an intelligence that wants to send organized pulses, but one hypothesis refers to a dead and very dense star, called, properly, "magnetar". The pulses would be according to this hypothesis generated by the rotation of the celestial body. Because of the rotational motion, in fact, the magnetar would be oriented toward the Earth, then, in the dormant phase of the signal, the same inclination would increase the distance from the instrument receptor of scientists.
