Water discoveries in space happen all the time. But this one’s actually a big deal, and not just because some scientists got excited (though they absolutely did). NASA’s Neil Gehrels Swift Observatory just spotted something remarkable: water vapor streaming off an interstellar comet called 3I/ATLAS.

Scientists have detected water vapor components in the interstellar object 3I/ATLAS, a significant discovery for understanding its composition and ori

Astronomers say the finding is a major advance in understanding how comets and planets form across the Galaxy.

NASA scientists have detected traces of water on the mysterious interstellar object 3I/Atlas, sparking new discussions about the possibility of life elsewhere in the universe.

NASA confirms water`s chemical signature on interstellar comet 3I/ATLAS, a discovery that could reveal secrets of distant planetary systems and the building blocks of life.

Scientists are observing an Earth-like exoplanet that may contain water using NASA's James Webb Space Telescope, the space agency said in a news release. The exoplanet, known as TRAPPIST-1 e, orbits the red dwarf star TRAPPIST-1. The system was discovered ...

The comet 3I/ATLAS, discovered on July 1, 2025, by the Asteroid Terrestrial-impact Last Alert System (ATLAS) in Hawaii, marks the third recorded interstellar object, following the discoveries of 1I/‘Oumuamua in 2017 and 2I/Borisov in 2019.

Near the Sun, where extreme heat is abundant, similar methods could, in principle, extract oxygen from CO₂ without added energy input. That means a comet or an interstellar body might generate its own power using internal compounds—CO, CO₂, and H₂O—as natural propellants.
