Scientists are weighing up the possibility of intercepting an interstellar object hurtling towards our solar system at speed. The mysterious intergalactic object is believed to have been ...

The interstellar interloper is zipping through our solar system at ludicrous speeds, clocking in at 37 miles (60 kilometers) per second.

A controversial new paper questions whether the interstellar object 3I/ATLAS is a potentially dangerous alien probe, similar to claims made about 'Oumuamua. But experts have called it "nonsense".

In a new, yet-to-be-peer-reviewed paper, Harvard astronomer Avi Loeb — the same scientist who suggested that 'Oumuamua, the first interstellar object ever detected back in 2017, was alien in ...

In comparison, the first known interstellar visitor, 1I/'Oumuamua, had an eccentricity of about 1.2, and 2I/Borisov came in at 3.6. 3I/ATLAS massively outpaces both.

Interstellar comet 3I/ATLAS shines in the sharpest view yet captured by the Hubble Space Telescope, helping astronomers determine the object’s size.

For only the third time, astronomers have found something passing through our solar system that came from outside the solar system. This interstellar object, known as 3I/ATLAS, is still pretty far ...
