Need a refresher about 3I/ATLAS? Here's everything to know about the interstellar object, including when the latest observations will be made.

Earth has a new friend — and it's been waiting for us to notice it for decades. In a new study published in the journal Research Notes of the American Astronomical Society, astronomers report the ...

The National Aeronautics and Space Administration has confirmed an interstellar object is passing through our solar system.

Earlier this week, the Sun unleashed a flurry of plasma and magnetic fields, or coronal mass ejection, at interstellar object ...

The Earth stands alone in the solar system as a habitable world, as far as we know. But that doesn’t mean we don’t get ...
