The Arecibo Observatory in Puerto Rico received radio signals from a red dwarf star 11 light years from Earth.

Scientists at the Arecibo Observatory in Puerto Rico on May 12 discovered unusual radio signals that most likely came from Ross 128, a red dwarf star, 2,800 times fainter than the Sun, 11 times from Earth. light years, according to Business Insider.

Abel Méndez, an astrobiologist at the University of Puerto Rico, said that when he observed Ross 128 for 10 minutes, he discovered that the signal strength increased and became almost cyclical. It is difficult to confirm that this is a signal from aliens, but this possibility is still possible.

“The Arecibo Observatory’s viewing angle is very wide, so the mysterious signal may not be emitted by the star but by another object, such as an alien communications satellite,” Méndez said. .

However, some scientists hypothesize that the radio signal originated from comets or bursts of energy on the star’s surface. Similar explosions on the surface of the Sun create magnetic storms, damaging satellites, power grids, and terrestrial communications systems, as well as endangering astronauts.

Méndez said scientists used the Arecibo Observatory to observe Ross 128 again from July 16 to collect more data.
