In 1977, the Ohio State University’s Big Ear radio telescope received an unusually strong narrowband radio signal, leading to widespread excitement about the possibility of having encountered evidence of life beyond Earth. In a new blog post, he suggested that interstellar object 3I/ATLAS, which is currently cruising through our solar system, could’ve sent off the signal back in 1977 — when it was still 600 times the distance between the Earth and Sun away from us. Signal, Loeb concluded that the “chance of two random directions in the sky being aligned to that level is about 0.6 percent.”“If the ‘Wow! Ever since it was first observed in July, 3I/ATLAS — only the third interstellar object ever spotted — has fascinated scientists. Signal, Loeb suggested that 3I/ATLAS would’ve had to have a power source of 0.5 to 2 gigawatts to send off the Wow!
