TUCSON, Ariz., March 16, 2011 /PRNewswire/ -- The recent Japanese earthquake and tsunami and the 2004 Indonesian earthquake and tsunami have shocked the world. Dr. Jeffrey Goodman, an archeologist and geologist who has spent years researching the Bible's stories of catastrophe, says that tsunamis that dwarf those of Japan and Indonesia are written about in the Bible. In his new book "THE COMETS OF GOD" Goodman says the Bible tells of a mega-tsunami that occurred in the past and a...

So you think global warming is a big problem? What could happen if a 25-million-ton chunk of rock slammed into Earth? When something similar happened 65 million years ago, the dinosaurs and other forms of life were wiped out."A collision with an object of this size traveling at an estimated 30,000 to 40,000 mile per hour would be catastrophic," according to NASA researcher and New York City College of Technology (City Tech) Associate Professor of Physics Gregory L. Matloff. His...

A team of NASA-funded researchers has unveiled a new theory that contends planets gained the final portions of their mass from a limited number of large comet or asteroid impacts more than 4.5 billion years ago. These impacts added less than one percent of the planets' mass. Scientists hope the research not only will provide a better historical picture of the birth and evolution of Earth, the moon and Mars, but also allow researchers to better explore what happened in our solar system's...

Scientists at Purdue University and Imperial College London have revised their popular "ËœImpact Effects Calculator', which allows anyone to calculate the potential damage a comet or asteroid would cause if it collided with the Earth. The interactive tool, available at http://www.purdue.edu/impactearth, lets users enter in specific details about the hypothetical impactor, such as its diameter and density, velocity, angle of entry and where it will hit the Earth. It then estimates...

New research challenges the controversial theory that an ancient comet impact devastated the Clovis people, one of the earliest known cultures to inhabit North America. Writing in the October issue of Current Anthropology, archaeologists Vance Holliday (University of Arizona) and David Meltzer (Southern Methodist University) argue that there is nothing in the archaeological record to suggest an abrupt collapse of Clovis populations. "Whether or not the proposed extraterrestrial impact...

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...

Scientists have discovered that a potentially hazardous asteroid might collide with Earth in 2182. The scientists used two mathematical models in order to determine the chance of impact. "The total impact probability of asteroid '(101955) 1999 RQ36' can be estimated in 0.00092 "“approximately one-in-a-thousand chance-, but what is most surprising is that over half of this chance (0.00054) corresponds to 2182," explains to SINC María Eugenia Sansaturio, co-author of...

Researchers sifting through Google Earth images have discovered what may be the world's best-preserved small impact crater in a remote area of the Sahara desert in southwestern Egypt.   The immaculate, 148 ft. wide crater was likely excavated by a fast-moving iron meteorite, a few thousand years ago, scientists said Thursday. Dubbed Kamil, the crater is remarkably preserved when compared with most of the other craters on the Earth's surface, many of which are partially eroded. The...

Lawmakers are looking for ways to keep Earth shielded from an asteroid or comet impact.  A new bill introduced to Congress proposes establishing a government-sponsored commission in order to study a major space rock collision with Earth and how prepared we are to face such a danger. There is a growing choir of concern regarding Near Earth Objects, or NEOs. Experts say that while the annual probability of the Earth being struck by a huge asteroid or comet is small, the consequences of...

Crater -- A crater is a circular depression on the surface of a planet, moon, asteroid, or other celestial body. Craters are typically caused by meteorite impacts, although some are caused by volcanic activity. In the center of craters on Earth a crater lake often accumulates, and in craters formed by meteorites a central island (caused by rebounding crustal rock after the impact) is usually a prominent feature in the lake. Ancient craters whose relief has disappeared leaving only a...

Near-Earth Asteroid -- Near-Earth asteroids (NEAs) are asteroids whose orbit intersects Earth's orbit and which may therefore pose a collision danger, as well as being most easily accessible for spacecraft from Earth. In fact, some near-Earth asteroids can be reached with much less ΔV than the Moon. The most famous near-Earth asteroid is 433 Eros that was visited by NASA's Near Earth Asteroid Rendezvous probe. A few hundred such near-Earth asteroids are known, ranging in size up...
