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 ...

Impact craters are everywhere in the solar system, ... Because the craters are fresh, their ejecta blankets haven't been eroded much, making it relatively easy to measure their original size.

Scientists used computer simulations to show that the way debris spreads from small impact craters on Mars, called ejecta mobility, can reveal what’s beneath the surface, including buried ice.

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 ...

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.

However, some new discoveries can unearth signatures of impact structures, such as “ejecta” materials thrown out of a crater during an asteroid impact.

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.

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 ...

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 ...
