Toward the end of last week, analysts declared that, on May 12, the 1,000 all inclusive (305 meters) Arecibo radio telescope in Puerto Rico identified a peculiar radio signal in the region of Ross 128, a red dwarf star that untruths only 11 light-years from Earth.
The signal was hypothetically predictable with a transmission from an outsider progress, the space experts stated, however they focused on that speculation was “at the base of numerous different clarifications.” Indeed, they pegged the main competitors as flares from Ross 128, discharges from some other protest in an indistinguishable field of view from the star, and a burst from at least one high-circling satellites.
Presently, follow-up perceptions — by Arecibo, and additionally the Green Bank Telescope in West Virginia and the Allen Telescope Array (ATA) in northern California — point to this last speculation as for the in all likelihood, colleagues said.

“The best clarification is that the signals are transmissions from at least one geostationary satellites,” Abel Mendez, executive of the Planetary Habitability Laboratory at the University of Puerto Rico, wrote in an announcement on July 21. (Geostationary satellites hover Earth at a height of around 22,300 miles, or 35,800 kilometers.)
“This clarifies why the signals were inside the satellite’s frequencies and just showed up and persevered in Ross 128; the star is near the heavenly equator, where numerous geostationary satellites are set,” Mendez included. “This reality, however, does not yet clarify the solid scattering like elements of the signals (diagonal lines in the figure); in any case, it is conceivable that different reflections caused these twists, yet we will require more opportunity to investigate this and different potential outcomes.”
Yet, despite the fact that it’s conceivable that the Ross 128 signal has a trite clarification, researchers should, in any case, follow up on comparable discoveries, later on, focused on Seth Shostak, a senior stargazer at the SETI (Search for Extraterrestrial Intelligence) Institute in Mountain View, California.
