The same image, but with the stars removed, showing 3I/Atlas in the center, visible as a bright fuzzy object with a faint tail pointing upward. With no stars in the image, the tail is easier to make out, it appears to be a little undulated.

This movie shows comet SWAN (circled) moving across the sky from Aug. 25 to Oct. 2, 2025. The movie was made by combining images from NASA’s PUNCH (Polarimeter to Unify the Corona and Heliosphere) mission that were not fully processed. Seams between individual images appear as black lines across the view. Bright objects have white spikes extending from them. Fainter stars and cosmic rays flicker in the background. The two bright objects the comet passes between (about halfway through the video) are the planet Mars (top) and the star Spica (bottom).

3 images of comets and auroras/airglows. Descriptions from the tweet - 1. Comet Swan (C/2025 R2) appears above Earth’s yellow-green airglow just before an orbital sunrise, at a distance of about 27.2 million miles (43.8 million kilometers) from the planet. The International Space Station was orbiting 264 miles above the Atlantic Ocean off the coast of Canada's most easterly province of Newfoundland and Labrador when this photograph was taken. 2. This long-exposure photograph shows a bright aurora radiating above Earth as Comet Lemmon (C/2025 A6) soared past the planet at a distance of about 57.2 million miles (92.1 million kilometers). The International Space Station was orbiting 263 miles above northern Minnesota at the time of this photograph. 3.

A 3D animated model of the inner Solar System, centered on the Sun. It displays the orbits of Earth, Mars, and Venus, with trajectories fading over time. The animation dynamically focuses and zooms in on the path of the comet, highlighting its trajectory through the solar system.
