Did a Space Rock Cook the Dinosaurs?

Imagine a giant space rock, bigger than a mountain, zooming through space! About 66 million years ago, one of these crashed into Earth with a HUGE bang! For a long time, scientists thought this crash caused a super long, cold winter that made all the plants die, and then the dinosaurs starved because there was no food.

But guess what? New detective work by scientists is telling a different story! They found clues that after the asteroid hit, it kicked up tons and tons of super-duper fine dust, like the tiniest powder you can imagine, way up into the sky. This dust wasn't just blocking the sun; it was doing something even crazier!
