Nasa discovers seven new dark comets and their link to Earth's origins; here’s what we know

NASA's discovery of seven new "dark comets" doubles the known population of these asteroid-like objects with cometary behavior.

Scientists believe they may hold clues to the origins of Earth's water and life, potentially delivering these vital ingredients during Earth's early formation.
