A pair of 35-million-year-old craters on Earth thought to have been carved by comets now appears to be the result of a broken asteroid that generated
a slowly delivered shower of debris over millions of years.
One crater is in Chesapeake Bay off the Maryland coast. The other, called the Popigai crater, is in north-central Siberia. Estimates of their age
suggest they were created a mere 10,000 years apart.
