The Latest Breaking News from 3I

As comet 3I/ATLAS nears its 29 October perihelion, scientists test whether its acceleration hints at alien propulsion—a bold 'mothership' theory led by Avi Loeb.

Astronomers are tracking interstellar object 3I/ATLAS as it passes near the Sun and Venus this week, marking a rare celestial alignment that could provide fresh insights into deep-space activity.

NASA scientists are investigating an unexplained energy burst from 3I/ATLAS, an interstellar comet emitting unusual gases and light patterns as it nears the Sun.

A massive coronal mass ejection (CME) is hurtling from the Sun's far side, setting a collision course for the unusual interstellar Comet 3I/ATLAS.

At the end of October Europa Clipper will fly in line with 3I/ATLAS’ ion tail — but will any of the charged particles reach the spacecraft, and will the spacecraft be ready to receive them?

An interstellar object the size of Manhattan, named 3I/ATLAS, is baffling scientists by emitting an industrial metal compound never before seen in nature. With a peculiar orbit and other anomalies, experts like Harvard's Dr Avi Loeb question if it could be evidence of alien technology.

Researchers have discovered that interstellar comet 3I/ATLAS has been shedding water, providing insights into the building blocks of life outside of our solar system and the evolution of interstellar comets.

The European Space Agency's ExoMars orbiter has captured the closest view yet of the interstellar comet 3I/ATLAS. The images reveal the comet's bright coma but show no signs of a tail.

The interstellar comet 3I/ATLAS does not come from our corner of the Milky Way, and may be a time capsule of the early galaxy, new research into its trajectory hints.
