Avi Loeb: Now best time for 3I/ATLAS to reveal alien tech

As 3I/ATLAS reaches its closest approach to the Sun, Harvard astrophysicist Avi Loeb says this could be the ideal moment for the interstellar object to reveal signs of alien technology — if it’s not a natural comet. Loeb tells "ChicagoNOW" he’s awaiting new high-resolution NASA images that could help determine the object’s true nature and explains how the International Asteroid Warning Network will be tracking its path.
