#3I/ATLAS

Observations of interstellar comet 3I/ATLAS after perihelion found a lower carbon-dioxide-to-water ratio than earlier space-based observations suggested, pointing to changing coma chemistry and a more layered interior.

A new analysis of James Webb Space Telescope observations indicates that interstellar comet 3I/ATLAS contains abundant methane, offering a rare chemical snapshot of material formed around another star.

ESA's Jupiter-bound JUICE spacecraft has observed interstellar visitor 3I/ATLAS venting about two tons of water per second, offering scientists a rare chance to study material from beyond the solar system while it is ac

As interstellar comet 3I/ATLAS prepares to exit the solar system permanently, NASA has released its complete observational dataset to the public, enabling researchers worldwide to extract discoveries from one of the rarest cosmic visitors ever recorded.

The discovery of 3I/ATLAS, the third confirmed interstellar visitor, signals a revolution in astronomical survey capabilities rather than a sudden increase in cosmic visitors.

ESA's JUICE probe photographed the third known interstellar visitor to our solar system, revealing a glowing coma and sweeping tail as the comet approaches the sun.
