WASHINGTON, D.C.: A “strong signal” detected by a radio telescope in Russia that is scanning the heavens for signs of extraterrestrial life has stirred interest among the scientific community. “No one is claiming that this is the work of an extraterrestrial civilization, but it is certainly worth further study,” said Paul Gilster, author of the Centauri Dreams website which covers peer-reviewed research on deep space exploration. The signal is from the direction of a HD164595, a star about 95 light-years from Earth. The star is known to have at least one planet, and may have more. The observation is being made public now, but was actually detected last year by the RATAN-600 radio telescope in Zelenchukskaya, Russia, he said. Experts say it is far too early to know what the signal means or where, precisely it came from. “But the signal is provocative enough that the RATAN-600 researchers are calling for permanent monitoring of this target,” wrote Gilster.
