Three Heliophysics Spacecraft Observe Interstellar Comet 3I/ATLAS
Traveling through our Solar System at a staggering 209,000 km (130,000 miles) per hour, 3I/ATLAS was made visible by using a series of colorized stacked images from September 11-25, 2025, using the Heliocentric Imager-1 instrument, a visible-light imager on NASA’s STEREO-A spacecraft.

NASA’s STEREO (Solar Terrestrial Relations Observatory), the NASA/ESA SOHO (Solar and Heliospheric Observatory), and NASA’s PUNCH (Polarimeter to Unify the Corona and Heliosphere) missions have the unique ability to observe areas of the sky near the Sun, which allowed them to track 3I/ATLAS as it passed behind our Sun as seen from Earth.
