A megatsunami swept over Mars after a massive asteroid hit the Red Planet

A Martian megatsunami — a giant killer wave that may have reached more than 80 stories high — may have raced across the Red Planet after a cosmic impact similar to the one that likely ended Earth’s age of dinosaurs, a new study finds.

Although the surface mars is now cold and dry, a large body of evidence indicates that an ocean’s worth of water covered the Red Planet billions of years ago. Previous research found signs that two meteor impacts could have caused a couple of megatsunamis (opens in new tab) about 3.4 billion years ago. The older tsunami inundated about 309,000 square miles (800,000 square kilometers), while the more recent one submerged an area of ​​about 386,000 square miles (1 million square kilometers).
