A burst of radio signals which may have originated from an alien satellite in deep space, in the line of sight leading to Ross 128 (also known as FI Virginis) may have been intercepted by the 1,000-foot-wide radio telescope at Puerto Rico's Arecibo Observatory. According to Abel Mendez, a planetary astrobiologist at the University of Puerto Rico "the signals consisted of broadband quasi-periodic non-polarized pulses with very strong dispersion-like features." Earth-based satellite use similar radio signals to communicate. Although downplaying the possibility of aliens, Mendez admitted that "communication satellites transmit in the frequencies we observed." However, there were (and are) no satellites (from Earth) in the field of view which can explain the signals. Instead, "they are unique to Ross 128, and observations of other stars immediately before and after did not show anything similar" according to Mendez. Ross 128, like other Ross stars, is a red dwarf, and is less than 11 light years from Earth (located in the constellation of Virgo). The Ross stars were first catalogued in 1926 by Frank Ross, and several are believed to possess multiple extrasolar planets which in turn have been the subject of speculation as to alien intelligent life. For example, Michael Kube-McDowel has targeted Ross 128 as the location of an abandoned colony of humans, whereas Gregory Benford--an astronomer and author of numerous science fiction stories--has pontificated about hunter-killer satellites and amphibious alien races living beneath the seas of a watery world orbiting Ross 128--satellites which would transmit communication signals perhaps similar to those detected by Mendez and colleagues. The radio signals reported by Mendez et al, are in fact, similar to radio signals employed by communication satellites and space craft, whereas it is not likely they are being emitted by Ross 128: "... there is the possibility that the signals were caused not by the star but another object in the line of sight" such as "communication satellites" says Mendez. The signals were detected in May of 2017. As summarized by Mendez: "Two weeks after these observations, we realized that there were some very peculiar signals in the 10-minute dynamic spectrum that we obtained from Ross 128 (GJ 447), observed May 12 at 8:53 PM AST (2017/05/13 00:53:55 UTC). The signals consisted of broadband quasi-periodic non-polarized pulses with very strong dispersion-like features. We believe that the signals are not local radio frequency interferences (RFI) since they are unique to Ross 128 and observations of other stars immediately before and after did not show anything similar."
