Follow reports by NASA from this amazing interstellar comet's visit to our solar system.
The interstellar comet 3I/ATLAS will soon leave our solar system, never to return, but the observations of the comet will live on in NASA’s public data archives. More than a dozen NASA science missions turned their instruments to observe the…
NASA’s SPHEREx mission turned its infrared gaze on interstellar comet 3I/ATLAS in December 2025, adding to the deep pool of information the agency has gathered on what is only the third such object to be discovered passing through our solar…
NASA’s TESS (Transiting Exoplanet Survey Satellite) observed the interstellar comet 3I/ATLAS during a special observation run from Jan. 15 to 22. Scientists will use the data to study the comet’s activity and rotation. Using TESS data from Jan. 15…
NASA’s Parker Solar Probe observed interstellar comet 3I/ATLAS from Oct. 18 to Nov. 5, 2025, with its WISPR (Wide-Field Imager for Solar Probe) instrument. The spacecraft snapped around 10 images of the comet per day. During this period, Parker Solar…
NASA’s Europa Clipper mission observed the interstellar comet 3I/ATLAS on Nov. 6 from a distance of about 102 million miles (164 million kilometers). Captured over a period of seven hours, the data gathered by the spacecraft’s Europa Ultraviolet Spectrograph (Europa-UVS)…
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…
NASA’s Psyche observed interstellar comet 3I/ATLAS over the course of eight hours on Sept. 8 and 9, when the comet was about 33 million miles (53 million kilometers) from the spacecraft. Captured by the mission’s multispectral imager, these observations help…
NASA’s STEREO (Solar Terrestrial Relations Observatory) observed interstellar comet 3I/ATLAS from Sept. 11 to Oct. 2. The STEREO mission, designed to study the Sun’s activity and its influence across the solar system, is part of a fleet of NASA spacecraft…
The ESA (European Space Agency) and NASA Solar and Heliospheric Observatory, or SOHO, spacecraft captured a glimpse of interstellar comet 3I/ATLAS on Oct. 15–26. During this time period, the spacecraft’s Large Angle and Spectrometric Coronagraph (LASCO) instrument suite spotted the…
NASA’s PUNCH (Polarimeter to Unify the Corona and Heliosphere) mission observed interstellar comet 3I/ATLAS during its passage through the inner solar system. The mission’s ability to observe areas of the sky near the Sun allowed PUNCH to track the comet as it passed close to…
