Artistâs impression shows the first interstellar object discovered in the Solar System, `Oumuamua. A mysterious object the size of Manhattan could be a hostile alien spacecraft and may attack Earth in November, according to a new study. Earlier this month, experts confirmed the discovery of a rare interstellar visitorâonly the third ever detectedâhurtling through our Solar System at extraordinary speed. A draft scientific paper, dated 22 July, has proposed that the object, 3I/ATLAS, might be alien technology and could make a surprise attack on our planet. The researchers suggest that 3I/ATLASâs orbit is such that it would make it easier for an intelligent alien craft to approach Earth without being noticed. They report that when it gets closest to the Sun (perihelion) in late November, the object will be hidden from Earthâs view, allowing it to carry out a secret high-speed manoeuvre to slow down and stay in the Solar System to secretly prepare for an attack.
