Comet 3I/ATLAS recently emerged from behind the glare of the sun to become visible to ground-based telescopes.

The unusual comet—which is to pass Earth again in the coming weeks—is only the third known object to visit us from outside the solar system.

Scientists from the European Space Agency have significantly narrowed down the trajectory of the interstellar visitor 3I/ATLAS thanks to data from the alien comet's recent flyby of Mars, allowing for more accurate future observations.

Interstellar comet 3I/ATLAS is again challenging astronomers' understanding of comet physics after new images captured from New Mexico revealed three separate ionic jets and an enormous sunward anti-tail extending millions of miles.
