Asteroid Caused Massive Firestorm Leading To Global Extinction
2013-03-28 05:17:03

redOrbit Staff & Wire Reports - Your Universe Online Researchers from the University of Colorado claim to have uncovered new evidence supporting the notion that a Manhattan-sized asteroid collided with the Earth some 66 million years ago, triggering a global firestorm that would have led to the extinction of 80 percent of the planet´s species. According to Douglas Robertson of the Cooperative Institute for Research in Environmental Sciences (CIRES) and colleagues, the firestorm...

Comet May Have Caused Chicxulub Crater And Dinosaur Extinction
2013-03-24 05:34:56

Brett Smith for redOrbit.com - Your Universe Online One of the most popular theories on the disappearance of the dinosaurs surrounds the 110 mile-wide Chicxulub crater in Mexico. Many scientists believe the extinction was caused by an asteroid that crashed into Earth, leaving only a massive crater behind. However, a group of American scientists is presenting a theory that the culprit was actually a speeding comet, not a relatively slow-moving asteroid as many theories assert....

Evidence Supports Dinosaur Extinction Level Event

Alan McStravick for redOrbit.com — Your Universe Online We´ve had an increasing fascination with comets and asteroids over the past several years. We´ve fictionally sent a rogue group of astronauts to detonate one of these heavenly travelers. We´ve seen the disastrous effect of a potential impact in both movies and on television. We´ve elevated our global anxiety tracking the trajectory of these large, quickly moving celestial bodies. And it seems our vigilance...

A cosmic one-two punch of colossal volcanic eruptions and meteorite strikes likely caused the mass-extinction event at the end of the Cretaceous period that is famous for killing the dinosaurs 65 million years ago, according to two Princeton University reports that reject the prevailing theory that the extinction was caused by a single large meteorite. Princeton-led researchers found that a trail of dead plankton spanning half a million years provides a timeline that links the mass...

Princeton Model Shows Fallout Of Giant Meteorite Strike

Seeking to better understand the level of death and destruction that would result from a large meteorite striking the Earth, Princeton University researchers have developed a new model that can not only more accurately simulate the seismic fallout of such an impact, but also help reveal new information about the surface and interior of planets based on past collisions. Princeton researchers created the first model to take into account Earth's elliptical shape, surface features and ocean...

The Chicxulub crater in Mexico, the site of the asteroid strike that brought the dinosaurs to extinction 65 million years ago, is among the highlights of ocean drilling projects proposed for the next decade, reports BBC News. The Integrated Ocean Drilling Program (IODP) plans to study the crater by drilling about a mile into the sea bed. IODP is also planning expeditions to study earthquakes, ancient climates and a long-term aim to penetrate the Earth's mantle for the first time. IODP...

A new study theorizes that the dinosaurs were wiped out 65 million years ago by at least two meteorite strikes rather than one. Scientists previously thought that a huge meteorite impact occurred in the Gulf of Mexico, wiping out the dinosaurs in one fell swoop. New evidence, however, suggests that a second impact occurred in the Ukraine, according to a BBC News report on Friday. The study findings were published in the journal Geology by a team lead by Professor David Jolley of Aberdeen...

Deforestation in the Democratic Republic of the Congo has unveiled what could be one of the largest impact craters discovered over the past 10 years, according to a noted Italian scientist. University of Padova scholar Giovanni Monegato, who presented his findings during the recent Lunar and Planetary Science Conference in Texas, was one of the researchers who spotted the 30-mile ring using satellite imagery. He states that the geologic feature, located near the Unia River, became...

For decades, scientists have accumulated ever-larger datasets that suggest an enormous space rock crashed into the ocean off the Yucatan Peninsula more than 65 million years ago, resulting in the Cretaceous-Paleogene (K-Pg) extinction. Recent research, supported in part by the National Science Foundation (NSF), suggested that the impact could have occurred 300,000 years prior to the K-Pg extinction, and that another cause--perhaps a second impact, or the long-lasting volcanic activity at the...

Researchers from the University of Granada (UGR) have compared the disaster caused by the Aznalc³llar spillage in the Doñana National Park in Andalusia 11 years ago with the biggest species extinction known to date. What do these two disasters have in common? The scientists say that carrying out comparisons of this kind will make it possible to find out how ecosystems recover following mass extinctions. Until now, scientists used to study the fossil record in order...
