Even interstellar comet 3I/ATLAS, at a distance of approximately 3.51 astronomical units (4.6) in relation to the Sun, was ...

For millions of years, a frozen wanderer drifted between the stars before slipping into our solar system as 3I/ATLAS—only the ...

Observations of interstellar object 3I/ATLAS show increased water, carbon dioxide, and organic gas release after its passage near the Sun, based on data from NASA’s SPHEREx mission ...

What does a body belonging to some other star system tell us when the rays of the sun begin heating it on the outside? An ...

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 ...

NASA’s SPHEREx telescope observed a dramatic outburst from interstellar comet 3I/ATLAS after its October 2025 solar flyby.

Comet 3I/ATLAS was full-on erupting into space in December 2025, after its close flyby of the sun, causing it to significantly brighten. Even water ice was quickly sublimating into gas in ...

Researchers from Auburn University have discovered hydroxyl gas coming from the interstellar comet 3I/ATLAS, a clear chemical sign of water. The Swift Observatory also detected a faint ultraviolet ...

NASA's SPHEREx space telescope detected methanol, cyanide and methane, key ingredients for life, in interstellar comet 3I/ATLAS during its December 2025 flyby.

The space telescope 'SPHEREx,' jointly developed by Korea and the U.S. National Aeronautics and Space Administration (NASA), has captured the emission of water and organic molecules from an ...

Using the Swift telescope, hydroxyl emissions glowed with ultraviolet light, resembling fireworks in slow motion. The presence of these signals, which are ...
