Double impact may have caused tsunami, global cooling Pieces of a giant asteroid or comet that broke apart over Earth may have crashed off Australia about 1,500 years ago, says a scientist who has found evidence of the possible impact craters. Satellite measurements of the Gulf of Carpentaria (see map) revealed tiny changes in sea level that are signs of impact craters on the seabed below, according to new research by marine geophysicist Dallas Abbott. Based on the satellite data, one crater should be about 11 miles (18 kilometers) wide, while the other should be 7.4 miles (12 kilometers) wide....

Researchers have shown that ancient Egyptian iron beads held at the UCL Petrie Museum were hammered from pieces of meteorites, rather than iron ore. The objects, which trace their origins to outer space, also predate the emergence of iron smelting by two millennia. Carefully hammered into thin sheets before being rolled into tubes, the nine beads – which are over 5000 years-old - were originally strung into a necklace together with other exotic minerals such as gold and gemstones, revealing the high value of this exotic material in ancient times. The study is published in the Journal of Archaeological Science....

Despite the name, there was iron in the Bronze Age. It was just extremely rare. Most famously, the pharaoh Tutankhamun had a headrest, bracelet and dagger made of iron. Other iron artifacts from the same time have also been found around the globe. The existence of these artifacts has led to an archaeological debate: was there, in fact, iron smelting in the Bronze Age? According to a new chemical analysis, the answer is no. The iron humans had during the Bronze Age came from space.

King Tut owned a dagger that was out of this world—literally. Researchers have recently published a study in the journal Meteoritics & Planetary Science that supports what has long been suspected: The ancient Egyptians were using meteoritic iron well before the spread of iron smelting technology. The recent study on King Tut’s dagger, led by researchers from Italy and Egypt, used X-ray fluorescence (XRF) spectrometry to analyze the composition of the iron blade. Iron meteorites mostly contain iron and nickel, and the results of the XRF analysis on King Tut’s dagger confirm that the blade is mostly composed of iron...

Italian and Egyptian researchers analyzed the metal with an X-ray fluorescence spectrometer to determine its chemical composition, and found its high nickel content, along with its levels of cobalt, “strongly suggests an extraterrestrial origin”. They compared the composition to known meteorites within 2,000km around the Red Sea coast of Egypt, and found similar levels in one meteorite.

We may still be looking for proof that aliens exist, but new research into some very curious ancient tools now reveals that humans were using extraterrestrial material long before mankind even dreamed of flying out of Earth’s atmosphere. The findings, which were published in the Journal of Archaeological Science, reveal that some incredibly old iron artifacts date to a time well before humans had the technological wit to smelt iron ore, and as it turns out, the iron used in their construction actually fell from the sky. Archaeologists have long suspected that the iron occasionally found amongst Bronze Age artifacts...

...The analyses revealed that the glass originate from the same glass workshops in Egypt that supplied the glass that the Egyptian Pharaoh Tutankhamun took with him to his grave in 1323 BC... Globalisation in the Bronze Age Twenty-three glass beads from Denmark were analysed using plasma-spectrometry. Without destroying the fragile beads, this technique makes it possible to compare the chemical composition of trace elements in the beads with reference material from Amarna in Egypt and Nippur in Mesopotamia, about 50 km south east of Baghdad in Iraq. The comparison showed that the chemical composition of the two sets of trace...

A team led by a Cardiff University archaeologist has reconstructed a 3,000-year-old glass furnace, showing that Ancient Egyptian glassmaking methods were much more advanced than previously thought. Dr Paul Nicholson, of the University’s School of History and Archaeology, is leader of an Egypt Exploration Society team working on the earliest fully excavated glassmaking site in the world. The site, at Amarna, on the banks of...

Mysterious Egyptian Glass Formed by Meteorite Strike, Study Says Stefan Lovgren for National Geographic News December 21, 2006 Strange specimens of natural glass found in the Egyptian desert are products of a meteorite slamming into Earth between 100,000 and 200,000 years ago, scientists have concluded. The glass—known locally as Dakhla glass—represents the first clear evidence of a meteorite striking an area populated by humans. At the time of the impact, the Dakhla Oasis, located in the western part of modern-day Egypt, resembled the African savanna and was inhabited by early humans, according to archaeological evidence (see Egypt map.) "This meteorite...

In 1996 in the Egyptian Museum in Cairo, Italian mineralogist Vincenzo de Michele spotted an unusual yellow-green gem in the middle of one of Tutankhamun's necklaces. The jewel was tested and found to be glass, but intriguingly it is older than the earliest Egyptian civilisation. Working with Egyptian geologist Aly Barakat, they traced its origins to unexplained chunks of glass found scattered in the sand in a remote region of the Sahara Desert. But the glass is itself a scientific enigma. How did it get to be there and who or what made it? Thursday's BBC Horizon programme reports an...

Scientists have discovered a huge crater in the Saharan desert, the largest one ever found there. The crater is about 19 miles (31 kilometers) wide, more than twice as big as the next largest Saharan crater known. It utterly dwarfs Meteor Crater in Arizona, which is about three-fourths of a mile (1.2 kilometers) in diameter. In fact, the newfound crater, in Egypt, was likely carved by a space rock that was itself roughly 0.75 miles wide in an event that would have been quite a shock, destroying everything for hundreds of miles. For comparison, the Chicxulub crater left by a...

King Tut was buried with a dagger made of an iron that literally came from space, says a new study into the composition of the iron blade from the sarcophagus of the boy king. Using non-invasive, portable X-ray fluorescence spectrometry, a team of Italian and Egyptian researchers confirmed that the iron of the dagger placed on the right thigh of King Tut's mummified body a has meteoric origin. ...

A team of scientists claims to have found the first-ever definitive evidence of a comet striking Earth. After conducting a series of analyses, the researchers determined that a mysterious black pebble discovered years ago in the Egyptian desert is a piece of a comet nucleus — the first ever discovered. "It’s a typical scientific euphoria when you eliminate all other options and come to the realization of what it must be," study lead author Jan Kramers, of the University of Johannesburg in South Africa, said in a statement. [Best Close Encounters of the Comet Kind] The pebble, which the team...

Cray Supercomputer at Sandia Helps Researchers Discover Origin of Mysterious Glass Found in King Tut's Tomb Released : Tuesday, July 31, 2007 7:26 AM Global supercomputer leader Cray Inc. (NASDAQ: CRAY) today announced that researchers running simulations on the Cray supercomputer at Sandia National Laboratories have re-created what could have happened 29 million years ago when an asteroid explosion turned Saharan sand into glass. The greenish natural glass, which can still be found scattered across remote stretches of the desert, was used by an artisan in ancient Egypt to carve a scarab that decorates one of the bejeweled breastplates buried...

King Tut's necklace shaped by fireball June 26, 2006 LONDON: Scientists believe they have solved the mystery surrounding a piece of rare natural glass at the centre of an elaborate necklace found among the treasures of Tutankhamun, the boy pharaoh. They think a fragile meteorite broke up as it entered the atmosphere, producing a fireball with temperatures over 1800C that turned the desert sand and rock into molten lava that became glass when it cooled. Experts have puzzled over the origin of the yellow-green glass -- carved into the shape of a scarab beetle -- since it was excavated in...

The “Near Earth Asteroid” discovered in 2013, which was called 2013 TX68 before being renamed to “B2Bomber,” will make its close approach to Earth on March 10. Slooh will broadcast the asteroid’s approach from Canary Islands Observatory. The event will be followed by discussions by Slooh Astronomer, Eric Edelman, and scientist Dr. Mark Boslough, an expert on planetary science and global catastrophes. The experts are unable to pin down the asteroid’s orbit, though it is suggested that it may pass as close as 11,000 miles, maybe even colliding with Earth in September 2017.
