Astronomers propose that micrometeorite bombardments were primarily responsible for the cooling of early climates on Mars and Earth, nearly four billion years ago. During these events, pieces of space rock no bigger than a sugar grain swooshed through the two atmospheres at great speeds. Scientists behind the new res... |
