A team of astronomers has taken the sharpest-ever picture of the unexpected interstellar comet 3I/ATLAS using the crisp ...

Yet NASA - and other experts - do not share his concerns and maintain 3I/ATLAS is simply an interstellar comet, thought to be around 7 miles (11.2 kilometers) wide. The US space agency has been ...

Scientists estimate the object to be more than 12-miles-wide, speeding at 37 miles-per-second, relative to the sun.

Does the scientific community as a whole share the notion that a newly discovered interstellar object 3I/ATLAS is an alien ...

Harvard astrophysicist Avi Loeb has cowritten a research paper speculating whether the comet 3I/ATLAS is in fact "hostile" alien technology.

Hubble has captured images of comet 3I/ATLAS, an ancient interstellar object likely 7 billion years old. As only the third known visitor from beyond the solar system, it offers rare insights into ...
