ELGIN, S.C. — A lot of attention has been generated in the South Carolina town of Elgin following the earthquakes there in recent months. But Elgin is also making headlines for a stunning discovery ...

New findings challenge a theory that a meteor explosion or impact thousands of years ago caused catastrophic fires over much of North America and Europe and triggered an abrupt global cooling period, ...

Around 12,800 years ago, the Northern Hemisphere got cold - really cold - in an abrupt climate change crisis called the Younger Dryas event. Now, researchers have found evidence that suggests that the ...

(Santa Barbara, Calif.) — Touchdown airbursts — a type of cosmic impact that may be more common than the crater-forming, dinosaur-killing kind — remain somewhat less understood. UC Santa Barbara Earth ...

At the end of the Pleistocene period, approximately 12,800 years ago — give or take a few centuries — a cosmic impact triggered an abrupt cooling episode that earth scientists refer to as the Younger ...

(Santa Barbara, Calif.) — Researchers continue to expand the case for the Younger Dryas Impact hypothesis. The idea proposes that a fragmented comet smashed into the Earth’s atmosphere 12,800 years ...

Earth’s surface bears the scars of obvious catastrophes, from dinosaur-killing craters to lava fields, but a growing body of ...

Some cosmic impacts are loud, fiery, and leave unmistakable craters. Others are quieter in geological terms, yet no less destructive. These “touchdown airbursts” occur when a comet or asteroid ...

Touchdown airbursts are a form of cosmic impact that may happen more often than the well-known, crater-forming events linked to mass extinctions ...

Cosmic “touchdown airbursts” — explosions of comets or asteroids above Earth’s surface — may be far more common and ...
