3I ATLAS (30 November 2025)
December 4, 2025 · ESA/Hubble · 3I/ATLAS
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. Hubble tracked the comet as it moved across the sky. As a result, background stars appear as streaks of light.
Hubble previously observed 3I/ATLAS in July , shortly after its discovery, and a number of observatories have since studied the comet as well. Observations are expected to continue for several more months as 3I/ATLAS heads out of the solar system.
