Euclid Space Telescope Discovers Distant New Comet C/2026 S1
The European Space Agency’s Euclid observatory has identified a long-period comet located over 800 million miles away while performing its dark energy survey.

The Euclid space telescope has identified a new celestial visitor named Comet C/2026 S1, according to a report from Popular Science on October 20, 2026. While the European Space Agency telescope was originally launched in 2023 to investigate the mysteries of dark matter and dark energy, it successfully detected this icy object within our solar system. At the time it was found, the comet was positioned more than 807.7 million miles from Earth, which is approximately 1.3 billion kilometers away.
The discovery was made by Mikko Pontinen of the University of Helsinki, who utilized specialized moving-object detection software to scan the telescope's data. The comet was spotted in the Deep Field North, located within the constellation Draco. These observations were captured over a period of several days, specifically from September 16 to September 24, 2026. Following the initial sighting, the International Astronomical Union Minor Planet Center officially confirmed the discovery on October 8.
Euclid usually avoids the ecliptic plane where most solar system objects are found, yet the telescope managed to document the comet as a distinct trail appearing across five different sets of images. The data revealed that the object possesses a fuzzy coma composed of gas and dust. Because of its extreme distance and low brightness, the comet remains too faint for amateur telescopes to see from Earth.
Initial orbital analysis shows that C/2026 S1 is a long-period comet, meaning it takes thousands of years to complete a single orbit around the Sun. Furthermore, its orbital path is unique as it arches high above the main plane of the solar system. This discovery highlights the telescope's ability to identify small, moving bodies even as it focuses on the invisible forces that shape the wider universe.
