Physicist Michio Kaku says interstellar object 3I/ATLAS may reveal signs of intelligent life if it gains energy near the Sun. Its unusual speed and trajectory have scientists divided.

Time is running short for scientists hoping to collect data from 3I/Atlas, a massive interstellar object hurtling away from the Sun.

NASA has activated its planetary defence network to monitor comet 3I/ATLAS, a rare interstellar object showing unusual behaviour as it approaches Earth.

A UN-endorsed group focused on planetary defense has locked onto 3I/ATLAS as the mysterious interstellar visitor fuels alien tech theories.

I/ATLAS puts the Planetary Defense Network on watch. NASA and ESA say no threat as IAWN drills tracking, while Harvard’s Avi Loeb raises an alien-origin idea.
