Strange Radio Waves Coming From Nearby Star

A star located at 11 light years from Earth is transmitting “strange” radio signals.

The mysterious signals come from Ross 128, an unexplored dwarf star. Researchers suggest that the signals appear “almost periodically”, suggesting that further investigation is needed to find the exact source.

Radio signals were detected via the Arecibo Observatory, a huge telescope in Puerto Rico. Professor Abel Mendez, an astrobiologist at the University of Puerto Rico, said that the signals were not transmitted by aliens, but it does not rule out this possibility.

He suggests that the signals could be transmitted by a satellite orbiting the star and blocking the field of view of the telescope. “Arecibo’s field of view is not very wide, so there is the possibility that a certain object in front of the star can transmit radio signals”, Mendez said. On his personal blog, Mendez said that “we have not noticed any object that can emit radio signals at such a high level”.

Another hypothesis suggests that the signals could come from starburst storms, an explosion of energy coming from the surface of the star. This type of explosions can travel at the speed of light and emit strong radio signals that destroy communications satellites on Earth.
