A star similar to the Sun signals the Earth: the signal "Wow" can be given by aliens

A star like the sun is giving signals to the earth

For a long time, the scientists have not been able to identify a potential signal source, which is called "Wow". It turns out that it is sent to the Earth by a star similar to the Sun. The scientists do not exclude that it may be sent by alien intelligence. In the last century, a radio telescope was developed and put into operation that was installed in Delaware. It served for over 30 years. And then its territory turned into a golf course.

The Big Ear Radio telescope, which was conventionally called the "Big Ear", was never considered either the largest radio telescope in the world, nor the most sensitive. But the Big Ear made one of the most astonishing observations in the history of astronomy, which has yet to be reasonably explained.


In the 70s of the last century, the radio telescope began to search for signals from extraterrestrial civilizations. On August 15, 1977, it recorded a strong intermittent signal. Its duration was 72 seconds. Against the background of the general noise, it stood out like a searchlight. Ground origin of the signal was immediately ruled out. An astronomer Jerry Eman recognized it as powerful and unusual, similar to "Wow!" And that word stuck with a strange cosmic phenomenon.

He and his colleagues came to the conclusion that the signal could be a fragment of extraterrestrial intelligence. You should wait for its repetition to study in detail. The researchers continued to study the part of the sky where the signal came from, but it did not repeat itself.

And nowhere else was anything like that observed. The astronomers checked the star catalogs, but failed to reveal the secret of the signal. This week, the astronomers said that they managed to find out what space object was sending those very strange signals. This discovery was made due to a long investigation. It was conducted by an amateur astronomer who was helped by a three-dimensional map of the Galaxy created at the Gaia space observatory.


It mapped nearly 1.3 billion stars, and the astronomers believe the mission to create such a map will last until 2024. An amateur astronomer Alberto Caballero believed the new database would help to uncover the secret of the signal. He searched for the source among stars similar to the Sun, among thousands of objects identified by equipment in the part from which the signal came.

There was a single potential target. It is the star 2MASS 19281982-2640123. It lies in the constellation Sagittarius, 1,800 light years away. It can be the identical twin of our Sun, with the same temperature, radius and brightness. The astronomers recognized the hobbyist as possible, naming the distant star as a potential candidate that could send strange signals.
