Using the Gemini North telescope in Hawaii, astronomers have captured an image of comet 3I/ATLAS, an interstellar object that was first detected on July 1, 2025, by the Asteroid Terrestrial-impact Last Alert System (ATLAS) for which the comet was named. The letter “I” means “interstellar,” and “3” indicates it is only the third object from another star system ever observed. The observations will help scientists study the characteristics of this rare object’s origin, orbit and composition.
Gemini North is in Hawaii and is one half of the International Gemini Observatory, funded in part by the U.S. National Science Foundation. The imagery reveals the comet’s compact coma — a cloud of gas and dust surrounding its icy nucleus.
“The sensitivity and scheduling agility of the International Gemini Observatory has provided critical early characterization of this interstellar wanderer,” says Martin Still, NSF program director for the International Gemini Observatory. “We look forward to a bounty of new data and insights as this object warms itself on sunlight before continuing its cold, dark journey between the stars.”
