Strange signals from Red dwarf star

Astronomers have detected mysterious radio signals coming from a red dwarf star –Ross 128 (GJ447), 2, 800 times dimmer than the Sun, located 11 light-years from Earth. The signals detected by astronomers at the University of Puerto Rico, in May 2017, using the Arecibo Observatory, a massive 1000-foot-wide (350meters)  radio telescope built inside of a Puerto Rican Sinkhole.

According to Mendez, there are three leading explanations for the signals. The solar flare-like emissions from Ross 128, could be emissions from some other object in the same field of view and burst of some sort from a satellite orbiting high above the Earth. Each of these hypotheses has its issues, he said. Solar flares of the type that could be responsible generally occur at lower frequencies and there are not a lot of other objects in the Ross 128 field of view, as we have never seen satellites emit bursts like that”.
