Scientists drilled into the Chixclub crater in the Gulf of Mexico to learn more about the end of the mesozoic era. They learned more than they expected, reports Katherine Kornei in The New York Times.
The first day of the Cenozoic was peppered with cataclysms. When the asteroid struck, it temporarily carved a hole 60 miles across and 20 miles deep. The impact triggered a tsunami moving away from the crater. It also catapulted rock into the upper atmosphere and beyond.
“Almost certainly some of the material would have reached the Moon,” Dr. Gulick said.
The largest pieces of debris rained back down to Earth within minutes, Dr. Gulick and his team say, pelting the scarred landscape with solidifying rock. Smaller particles lingered for longer periods, and glassy blobs known as tektites, formed when falling, molten rock cools, have been found across North America and dated to the Chicxulub impact. Within about 30 minutes, ocean water began to flood back into the crater through a gap in its northeastern rim, the researchers suggest.
Researchers successfully revived ancient microbes, some more than 100 million years old, that were buried in the seafloor. During an expedition to the South Pacific Gyre, the scientists from the Japan Agency for Marine-Earth Science and Technology (JAMSTEC) and their colleagues drilled into the ocean sediment almost 6,000 meters below the surface. “Our main question […]
My family stopped wiping down all our groceries to “disinfect” them a couple months ago, mostly because of hygiene exhaustion. Then in May, the Center for Disease Control and Prevention clarified its own Web page about how COVID-19 spreads to state that “based on data from lab studies on COVID-19 and what we know about […]
I’d totally go.
