There was no sign of life at Gliese 581

The hunt for other extraterrestrial civilizations has just been armed with new weapons, but the first military outpost did not produce satisfactory results.

Astronomers from Curtin University (Australia) used radio telescopes at three observatories to 'eavesdrop' the star system Gliese 581 , which is 20 light-years away from the earth.

Red dwarf Gliese 581 is thought to contain two planets capable of carrying life, according to previous research by Earth experts.

Due to being a red dwarf, Gliese 581 is smaller in size and less light than our sun. Therefore, the area that is capable of containing life around this star is more crowded than the solar system.

Accordingly, Gliese 581d - a super-Earth with 7 times the mass of the Earth - is rotating in the outer ring of the area that can survive life, with an orbit of 64 days long.

Gleise 581g - 3 times the mass of the earth - is more impressive when it only takes 37 days to complete a spin.

After 8 hours of investigation Gliese 581, a total of 222 radio signals were detected, but no signal came from the star system, according to a report published in The Astrophysical Journal.

Although the first departure failed, experts pursuing the SETI program (seeking extraterrestrial civilization) said Gliese 581 is just one of millions of potential star systems that contain life in the universe. immense.

The Kepler space telescope estimates that there are about 50 billion planets in the Milky Way, with 500 million planets in the region that may exist.
