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...

Scientist Calls Clovis Comet Theory Bogus
2013-01-30 20:42:49

Lee Rannals for redOrbit.com — Your Universe Online Researchers are contradicting one hypothesis that comet explosions may have ended the 9,000-year-old Clovis culture. The Clovis comet hypothesis was first reported in 2007, claiming a comet initiated the Younger Dryas cold period nearly 13,000 years ago. This period, also known as the Big Freeze, was a brief period of cold climatic conditions and drought, causing the collapse of the North American ice sheets. According to the...

Moon Formation - Evidence Backs Up Giant Impact Theory

[ Watch the Video: What is the Moon? ] | [ Watch the Video: Planetary Demolition Derby ] Lee Rannals for redOrbit.com - Your Universe Online Scientists are backing up a theory, claiming that the Moon was created when a planetary body the size of Mars collided with Earth. Planetary scientists found evidence that backs up the Giant Impact Theory, which was first proposed at a conference in 1975. The Giant Impact Theory says that Earth´s moon was created in an apocalyptic...

Amateur Astronomers Catch Rare Explosion Sighting On Jupiter
2012-09-12 07:41:43

Lawrence LeBlond for redOrbit.com - Your Universe Online Sometime early Monday morning while most of the country was in bed dreaming of sweet nothings, at least two amateur astronomers were out blazing the night skies looking for action. And what they found was the event of a lifetime: A two-second white flash on the surface of Jupiter. Amateur astronomer Dan Peterson, from Racine, Wisconsin, first reported his sighting of the explosion on Jupiter on the cloudynights.com forum. A second...

Moon Formation From Giant Hit-and-run Impact
2012-07-30 04:42:40

redOrbit Staff & Wire Reports - Your Universe Online While scientists tend to accept the theory that the Moon was formed following a collision between a young Earth and a second planet, new research published online earlier this month suggests that the impactor might have been larger and traveling faster than previously believed. Current theory suggests that Earth's satellite was formed when the protoplanet was hit by a second world, believed to have been about the size of Mars,...

Image 1 - New Study Supports Theory Of Extraterrestrial Impact
2012-03-06 04:37:04

A 16-member international team of researchers that includes James Kennett, professor of earth science at UC Santa Barbara, has identified a nearly 13,000-year-old layer of thin, dark sediment buried in the floor of Lake Cuitzeo in central Mexico. The sediment layer contains an exotic assemblage of materials, including nanodiamonds, impact spherules, and more, which, according to the researchers, are the result of a cosmic body impacting Earth. These new data are the latest to strongly...

Around 250 million years ago, most life on Earth was wiped out in an extinction known as the “Great Dying.” A team led by University of Cincinnati geologist Thomas J. Algeo finds that the end came slowly from thousands of centuries of volcanic activity. A painstakingly detailed investigation shows that mass extinctions need not be sudden events. The deadliest mass extinction of all took a long time to kill 90 percent of Earth´s marine life, and it killed in stages,...

Image 1 - Researchers Pinpoint Date, Rate Of Earth's Most Extreme Extinction
2011-11-19 04:34:24

Results stem from largest ever examination of fossil marine species 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. A team of researchers from North America and China have published a paper in Science this week which explicitly provides the date and rate of extinction. "This is the first paper to provide rates of such massive extinction," says Dr. Charles Henderson,...

Image 1 - Land Animals Suffered Catastrophic Losses After Permian Period
2011-10-26 06:31:51

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. As much as 90 percent of ocean organisms were extinguished, ushering in a new order of marine species, some of which we still see today. But while land dwellers certainly sustained major losses, the extent of extinction and the reshuffling afterward were less clear. In a paper published in the journal Proceedings of the Royal Society B,...

Results contradict several theories for cause of extinction 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. David Fastovsky, URI professor of geosciences, and graduate student David Tarailo found that...

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...

call-note
  • The call or cry of a bird or other animal to its mate or its young.
'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
