The Subaru Telescope observed the interstellar comet 3I/ATLAS on January 7, 2026, after it made its closest approach to the sun. By observing colors in the coma around the comet, astronomers could ...

3I/ATLAS Leaked NASA Pics Fuel Alien Craft Buzz: Harvard Hints at Maneuver, But Science Says No For decades, we have looked up at the night sky with a sense of predictable comfort. We understand the ...

Harvard scientist Avi Loeb has offered a provocative analysis of the interstellar comet 3I/ATLAS, suggesting its chemical composition raises questions about whether such objects could seed life on ...

Interstellar comet 3I/ATLAS is seen in this composite image captured on Nov. 6 by the Europa Ultraviolet Spectrograph instrument on NASA’s Europa Clipper spacecraft, from a distance of around 102 ...

Comet 3I/ATLAS was discovered on July 1, 2025, by the Asteroid Terrestrial-impact Last Alert System (ATLAS) telescope in Chile. The designation “3I” marks it as the third confirmed interstellar object ...

Astronomers have revealed new details about the make-up and age of a visiting comet that was born around a distant star. They conclude that the composition of 3I/Atlas is strikingly different from any ...

The interstellar object, 3I/ATLAS, was first discovered in July 2025, and made its closest approach to the sun (perihelion) in late October. New observations of 3I/ATLAS were taken in December from ...

A strange interstellar comet discovered last year and speculated by a prominent astronomer to be an alien spacecraft could be older than our Solar System, according to a new study. The comet, first ...

Comet 3I/Atlas is now heading out of the solar system and into interstellar space, but scientists are still analyzing the data it left behind as it passed through our cosmic neighborhood. A new study, ...
