The SETI Institute has announced that interstellar comet 3I/Atlas, which passed through our solar system, is entirely a natural object, dismissing earlier speculations about alien technology. Discovered last summer, it is only the third confirmed interstellar object, with previous ones also deemed natural. NASA's observations noted its closest approach to Earth was 167 million miles in December, while it swung past Mars at a distance of 19 million miles in October. SETI's extensive radio scans, lasting over seven hours, filtered through nearly 74 million signals, ultimately finding all signals traced back to Earth-based sources. Co-author Valeria Garcia Lopez highlighted the significance of these findings in demonstrating the realistic potential for detecting extraterrestrial signals. The comet, currently moving back to interstellar space, is estimated to be between 1,444 feet and 3.5 miles long and could be as old as 11 billion years, making it twice as old as our sun.
