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. Traveling through our Solar System at a staggering 209,000 km (130,000 miles) per hour, 3I/ATLAS was made visible...

The image shows NGC 1866 superimposed with a false color image from the MUSE data cube, where the ionized shell of the planetary nebula Ka LMC 1 is seen as a red ring. The grayscale insets illustrate the different size of the ionized shells of singly ionized nitrogen [N II] and doubly ionized oxygen [O III]. The magnified Hubble image near the center of the ring reveals the presence of a pale blue star -- most probably the hot central star of Ka LMC 1. Image credit: AIP / M.M.
