The 3I/ATLAS comet that will visit our solar system continues to interest Harvard science professor Avi Loeb, who has speculated it could be alien technology. Loeb tells "NewsNation Prime" we need to "use all space assets" to learn about the hurtling object. "If this happens to not be a comet, this will be a wake-up call," Loeb says. #interstellar #space #alientechnology | NewsNation
