The Hubble Space Telescope has captured the best picture yet of a high-speed comet visiting our solar system from another star.

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.

If you imagined that capturing a cosmic speedster was as easy as aiming a rocket and blasting, forget it intercepting ...

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

Scientists are exploring various proposals to repurpose existing spacecraft in order to chase after the interstellar object ...
