A monumental discovery has revealed that an asteroid struck the East Coast of North America roughly 35 million years ago, ...

Roughly 35 million years ago, a massive asteroid slammed into the Atlantic Ocean near what’s now the East Coast. The impact ...

The furthest secondary craters found by the researchers indicated that some of the ejecta from the impact were launched as far as 1,150 miles (1,850 km). That's about four times the length of the ...

A new study finds that ejecta blankets -- the layers of rock and other material blasted out of a crater by an impact -- can vary in size depending upon what materials are present beneath the ...

Geologists have found evidence of impacts, such as ejecta (material flung far away from the impact), melted rocks, and high-pressure minerals from more than 3.5 billion years ago.

Ultra-high-speed movie showing two views of an impact flash, and crater and ejecta development during the first few microseconds, for a stainless steel sphere impacting an aluminum alloy plate at ...

He harkens back to Gene Shoemaker's work at Meteor Crater to appreciate the process of impact cratering, excavation and ejecta deposits. "Those markers are so evidently available and readily visible.

This map shows the trajectories of ejecta fragments from a theorized asteroid impact some 280 million years ago. Researchers say the orientation of confirmed and possible craters, marked with ...

The tektites also offer clues about the missing crater itself. In 2007 Shyam Prasad, a scientist at India’s National Institute of Oceanography, modeled the impact event required to produce the ...
