De onde veio o cometa 3I/ATLAS?

Um astrofísico de Harvard propôs uma hipótese surpreendente sobre o cometa 3I/ATLAS.

Avi Loeb sugeriu que o objeto pode não ser natural, mas sim uma possível nave alienígena.

O cometa teria mais de 50 bilhões de toneladas, cerca de um milhão de vezes mais que o 1I/Oumuamua.

Loeb acredita que os jatos do 3I/ATLAS poderiam funcionar como propulsores tecnológicos, indicando origem artificial.

O objeto se aproximará da Terra em dezembro, e a sonda JUICE, da ESA, deve analisá-lo ainda em novembro.

A NASA já detectou gás hidroxila no cometa, um sinal de presença de água e possível origem interestelar.

Apesar da especulação, não há evidências de que o 3I/ATLAS represente ameaça ou seja uma nave alienígena.

Astrônomos seguem monitorando o cometa, que intriga pela sua massa, velocidade e comportamento fora do comum.
