K2-155 radio pulse: what China’s FAST found

This news report covers a narrow-band radio pulse, designated NBS 260108, identified in archived observations from China’s FAST radio telescope. The signal came from the direction of K2-155, a star system about 238 light-years from Earth.

K2-155 has three super-Earths, including one near its star’s habitable zone. The pulse’s unusual frequency characteristics made it a candidate for a possible technological signal. But there is no proof that it came from an alien civilization. Interference from human technology or the telescope’s equipment remains the more likely explanation.
