I/ATLAS is set to make its closest approach to Earth, sparking new theories of alien origins due to the latest observed ...

The path of comet 3I/ATLAS through the solar system has been predicted with an accuracy 10 times greater than previous estimates, thanks to images taken by a European Space Agency spacecraft orbiting ...

Interstellar objects like 3I/ATLAS are most likely to enter our solar system from two specific directions, a new study suggests. What does it mean for Earth? When you purchase through links on our ...

Even the best telescopes can’t see exoplanets. It’s all about watching for jiggly stars, blue shifts, and transits.
