UN says planetary defenses will observe interstellar comet 3I/ATLAS

The United Nations (UN) has confirmed that Earth’s planetary defenses will be observing the interstellar comet 3I/ATLAS as it races through our solar system. 

Starting on November 27, a global team of scientists with the International Asteroid Warning Network (IAWN) will kick off a two–month campaign to track the comet as it nears our planet.

‘While it poses no threat, comet 3I/ATLAS presents a great opportunity for the IAWN community to perform an observing exercise due to its prolonged observability from Earth and high interest to the scientific community,’ the UN explains on its website. 

‘This 3I/ATLAS campaign is the 8th IAWN observing exercise since 2017 – IAWN holds these exercises roughly once a year.’

While 3I/ATLAS was only discovered in July 2025, the UN explained that this ‘comet campaign’ has long been planned. 

‘IAWN had been planning to do a Fall 2025 comet campaign since 2024 to exercise capabilities for measuring the position of comets, which pose additional astrometric challenges as they appear as fuzzy extended objects compared to point–like asteroids in a telescope’s field of view,’ it added. 

The news comes shortly after NASA put claims that the object could be an alien spacecraft to bed once and for all. 

‘We want very much to find signs of life in the universe… but 3I/ATLAS is a comet,’ said Amit Kshatriya, a senior NASA official, at a press conference. 

Since it was first spotted in July, the object – dubbed 3I/ATLAS – has captivated scientists and internet users alike, even prompting Kim Kardashian to ask NASA for answers.

Many scientists maintained it was merely a comet visiting us from a different solar system. 

However, others – including a member of US Congress and a Harvard researcher – were convinced that the object was an alien spacecraft. 

Last week, NASA released photos snapped by three of its Mars spacecraft as they passed just 18 million miles away from the object. 

These pictures finally put any speculation to rest, as they confirmed the object’s identity.

And unfortunately for alien hunters, the US space agency says that 3I/ATLAS is a comet.  

The one man holding on to hope that the object could be extraterrestrial is Harvard professor Avi Loeb, who has shared new amateur telescope images of the interstellar object, captured between November 22 and November 24.

The photos reveal a glowing, fuzzy ‘head’ called a coma, along with a narrow tail stretching over 600,000 miles and pointing toward the sun instead of away from it like a typical comet.

One appears to reveal the shape of 3I/ATLAS, showing a cone–like object covered in a bright haze.

The images came from everyday skywatchers using small backyard telescopes around the world, including in Japan, Spain, and Chile.

Professor Loeb noted that a clear shot of the object on November 22, which showed its bright green body and long ‘anti–tail,’ was taken by Mitsunori Tsumura using a common 20–inch backyard telescope used by stargazers worldwide.

Another caught a sharp image of the interstellar visitor over Spain that same night using a 12.4–inch telescope – a very popular size used by hobbyists in their backyards.

Perhaps the sharpest picture Professor Loeb highlighted came from Paul Craggs of Canada, who was able to capture a clear image of the comet’s current shape while traveling over North America on November 21.
