William Shatner makes a planetary plea — Musk's response might ... Its reclassification not only altered the astronomical model but also challenged how people relate to celestial objects on ...

This knowledge reshapes how scientists model the life cycles of planetary systems. It also helps refine predictions about the stability of distant worlds that orbit close to their stars.

For decades, many scientists have relied on the "hard steps" model to suggest that intelligent life is rare — the improbable result of a series of unlikely evolutionary leaps. But new research by ...

Planetary defense is knowing what's out there ... Those models are very similar. Europe's model is a little different than the model we use. But that's actually a strength. We compare results ...
