NASA’s Hubble Space Telescope reobserved interstellar comet 3I/ATLAS Nov. 30, with its Wide Field Camera 3 instrument. At the time, the comet was about 178 million miles (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 NASA missions 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.
