Latest Impact events Stories
It's well known that Earth's most severe mass extinction occurred about 250 million years ago. What's not well known is the specific time when the extinctions occurred....until now.
The cataclysmic events that marked the end of the Permian Period some 252 million years ago were a watershed moment in the history of life on Earth.
While the cause of the mass extinction that occurred between the Permian and Triassic periods is still uncertain, two University of Rhode Island researchers collected data that show that terrestrial biodiversity recovered much faster than previously thought, potentially contradicting several theories for the cause of the extinction.
The end-Permian extinction, by far the most dramatic biological crisis to affect life on Earth, may not have been as catastrophic for some creatures as previously thought.
A hurtling asteroid about the size of the Titanic caused the scar that appeared in Jupiter's atmosphere on July 19, 2009.
After a volcanic eruption that occurred around 250 million years ago almost 95 percent of all primitive life living in the ocean and 70 percent of all animals evolving on land were wiped out.
Geologists at Brown University and the University of Washington have a cautionary tale: Lose enough species in the oceans, and the entire ecosystem could collapse.
An influx of invasive species can stop the dominant natural process of new species formation and trigger mass extinction events.
More than 251 million years ago, at the end of the Permian period, Earth almost became a lifeless planet.
WASHINGTON, Sept. 9 /PRNewswire-USNewswire/ -- Amateur astronomers using backyard telescopes were the first to detect two small objects that burned up in Jupiter's atmosphere on June 3 and Aug. 20.
Comet Shoemaker-Levy 9 -- Comet Shoemaker-Levy 9 is so-named because it was the ninth short-period comet discovered by Carolyn and Eugene Shoemaker and David Levy. It was first detected in a photograph taken on the night of March 24, 1993 with the 0.4-meter Schmidt telescope at the Mount Palomar observatory in California, and subsequently observed by many other astronomers. The comet was extremely unusual because it was in fragments, evidently due to a close encounter with the planet...
