Massive interstellar object 3I/ATLAS, larger than Manhattan, shows unusual glow pattern and planetary alignment that Harvard physicist calls potentially technological.

STARRS Observatory in Hawaii made history in 2017 when they detected 'Oumuamua, the first interstellar object (ISO) ever ...

A controversial new paper questions whether the interstellar object 3I/ATLAS is a potentially dangerous alien probe, similar ...

An interstellar comet spotted by NASA is headed for our solar system, showing up near Earth later this year, but it's another ...

I/ATLAS is just the third recorded interstellar object to enter the solar system. However, the scientific consensus is that ...

A Harvard University astrophysicist has suggested the incoming interstellar object 3I/ATLAS could be an alien probe. But NASA ...

In a groundbreaking study,Harvard physicist Dr. Avi Loeb has brought new attention to an unusual interstellar object, ...

Currently, 3I/ATLAS is visible only with large, sensitive telescopes. It sits in the constellation Sagittarius and is incredibly faint, about 2.5 million times dimmer than Polaris.

The space rock 3I/ATLAS is only the third confirmed interstellar object discovered by astronomers, following 'Oumuamua and the comet Borisov. While astronomers are still busily collecting data on the ...

"The consequences, should the hypothesis turn out to be correct, could potentially be dire for humanity," said Avi Loeb.

However, we might also want to look for hints of alien origin. One very strong piece of evidence would be any kind of radio waves coming from the probe as a form of communication. This is assuming the ...

Instead, scientists are looking into existing spacecraft already in orbit around other planets. Harvard Professor Avi Loeb ...
