NASA’s Planetary Defense Team Targets Comet 3I/ATLAS

The Planetary Defense Group, with backing from NASA, has commenced efforts to locate Comet 3I/ATLAS after noticing some rather strange behavior.

This comet, roughly the size of Manhattan, is intriguing as it may contain extraterrestrial technology. The International Asteroid Warning Network (IAWN) categorizes it as a potential threat. This organization unites experts and agencies on a global scale, coordinated by NASA, to identify and track potentially hazardous asteroids and near-Earth objects while evaluating their risks to our planet.

It’s actually the first instance of the group focusing on an interstellar object in a campaign like this, fine-tuning its abilities and preparing for any celestial threats. The New York Post mentions that 3I/ATLAS was first captured by the Hubble telescope on July 21, and it presents some peculiar characteristics for a comet.

The comet exhibits unusual traits, such as a stream of particle jets directed toward the Sun, contrary to what is typically observed. Instead of the usual flow, it has been reportedly ejecting columns that lack iron and are releasing about 4 grams of nickel every second, which is quite rare for a comet.

In a discussion with the New York Post, Dr. Avi Loeb, an astrophysicist at Harvard, noted that nickel tetracarbonyl—one of the emitted substances—has only been linked to human production.

Loeb suggests that the object’s unusual acceleration and its odd trajectory, bringing it close to several planets like Mars, Jupiter, and Venus, could indicate it’s an alien probe observing Earth. He articulated these thoughts in his paper, as cited by the Post.

Looking ahead, IAWN is set to initiate a “comet campaign” from November 27, 2025, to January 27, 2026, aimed at accurately determining the location of Comet 3I/ATLAS.
