Researchers constantly receive signals from space that come from natural objects. But among them may be hints of the existence of intelligent aliens. Not surprisingly, in 1967, scientists believed in the detection of aliens.
In 1967, Jocelyn Bell and Anthony Hewish recorded a radio signal that reached a period of 1.337302088331 seconds, and the pulse width was 0.04 seconds. It was possible to determine the coordinates and characteristics.
At first, the researchers considered that this was a mistake in the observations or a consequence of some noise. The fact is that previously they did not catch such an ideal repeat regularity. However, a thorough check showed that the signals really exist and come from a single source.
Then the idea arose that aliens trying to contact us, sending an encrypted message. The signal became a joke called LGM-1 (little green men 1).
Anthony Hewish told:
“It was hard to believe that we really managed to get a message from an extraterrestrial developed life. Of course, this idea arose in our head, especially since we could not prove that the signal was created naturally, and not artificially. We did not know how to explain it and who to ask for help ”.
But then the situation changed, because we managed to find another signal in another place, which also came to Earth with a certain regularity. What scientists have discovered?
It turned out that in 1967, researchers recorded the first-ever pulsar. Recall that we are talking about cosmic radiation sources (a neutron star with a magnetic field), which send pulses to the Earth. The find was PSR B1919 + 21, distant from us by 2280 light years and located on the territory of the constellation Chanterelle. The mass of PSR B1919 + 21 is 1.4 times higher than the solar indicators.
Scientists noted that the signal from this object was fixed back in 1919 and, most likely, it was possible to find many more similar ones. However, they were ignored and perceived as a system error, so PSR B1919 + 21, although it did not turn out to be a signal from the aliens, was remembered in history as the first pulsar found.
