The NASA/ESA Hubble Space Telescope reobserved interstellar comet 3I/ATLAS on 30 November with its Wide Field Camera 3 instrument. At the time, the comet was about 286 million kilometers from Earth.

Scientists confirmed that the interstellar comet 3I/ATLAS, which passed closest to Earth in December 2025, showed no detectable technosignatures strong enough to suggest it is an alien spacecraft.
