Astronomers observing the interstellar object 3I/ATLAS say it is showing unexpected movement as it travels through the Solar System. The latest measurements reveal a slight but measurable acceleration that does not align easily with standard models of comet behaviour.
The finding, first reported by NASA engineers and later analysed by international research teams, has drawn both interest and caution across the astronomy community. Some researchers believe the change can be explained by natural outgassing, while others say further evidence is needed to confirm the source of the motion.
