Spacecraft have revealed that the comet—which one scientist suggests could be an alien spacecraft—is now "distinctly bluer than the Sun."

Harvard astrophysicist Avi Loeb, in a recent conversation regarding the interstellar object 3I/ATLAS, stirred global debate. Loeb, who had earlier claimed that 2017’s ‘Oumuamua could be alien technology, now argues that 3I/ATLAS might also be of artificial origin, setting off another storm in the scientific community.

Physicist Avi Loeb sheds light on a recent study which observes the interstellar object glowing brighter than before and becoming bluer than the Sun

I/ATLAS has unexpectedly become bluer than the Sun, hinting that it could be emitting light, not just reflecting it — a sign it may be composed of something far beyond ordinary comet material.
