Scientists finally solved the mystery of Earth's greatest mass extinction

Why do beaches today have seashells from clams and snails instead of brachiopods? A new study suggests the answer lies in Earth's greatest mass extinction, when warming oceans and falling oxygen levels wiped out animals that couldn't adapt. Species with body plans and metabolisms

Roman telescope will spot distant black holes that shred stars

How do black holes at the centers of galaxies form and grow over time? To answer this question, scientists need to detect and study supermassive black holes at great distances that existed much earlier in the universe's history. New research suggests NASA's Nancy Grace Roman Spac
