Interstellar comet 3I/ATLAS is leaking water in space, NASA says its unlike anything ever seen before

Astronomers are stunned by interstellar comet 3I/ATLAS releasing water vapor unusually far from the Sun. This rare event, detected by NASA's Swift Observatory, suggests microscopic ice grains are sublimating, challenging existing cometary models. The discovery offers vital insights into how life's building blocks travel across the galaxy, highlighting the diverse origins of planetary materials.
