NASA observes largest Oort Cloud comet, C/2014 UN271, exploding with CO gas jets, thanks to ALMA’s deep-space capabilities.

A recent study indicates a small chance that Earth could be ejected from our solar system due to passing stars. Simulations ...

If our solar system seems stable, it's because our short lifespans make it seem that way. Earth revolves, night follows day, the moon moves through light and shadow, and the sun hangs in the sky. But ...
