    ...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...

    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.)

    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...

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...

    You’re probably as eager as I am for new images of Pluto and Ceres as both New Horizons and Dawn push ever closer to their respective little worlds. Recent photos, of which there are only a few, reveal some wild new features including what appears to a large crater on Pluto. In the end, this apparent large impact might only be a contrast effect or worse, an artifact of over-processing, but there’s no denying its strong resemblance to foreshortened, shadow-filled craters seen on the Moon and other moons. It’s also encouraging that an earlier photo from June 27 shows the...

The bizarre wedge-shaped structure with rows of seven light-like dots along its edge appears on the lunar surface. It was discovered on the Google Moon viewer at coordinates 22042'38.46N and 142034'44.52E. Speculation has exploded over the images of the anomaly that UFO websites have likened to an alien lunar base or spaceship. There are also theories that it is an alien spaceship nestled under the dust of the moon or even a secret moon base occupied by humans.

    SYDNEY: An Australian Aboriginal 'Dreaming' story has helped experts uncover a meteorite impact crater in the outback of the Northern Territory. Duane Hamacher, an astrophysicist studying Aboriginal astronomy at Sydney's Macquarie University, used Google Maps to search for the signs of impact craters in areas related to Aboriginal stories of stars or stones falling from the sky. One story, from the folklore of the Arrernte people, is about a star falling to Earth at a site called Puka. This led to a search on Google Maps of Palm Valley, about 130 km southwest of Alice Springs. Here Hamacher discovered what...

    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...

    Connect the dots: 1) Heard about a new (small) eruption of Piton de la Fournaise. 2) Piton de la Fournaise is the current "expression" of the La Reunion mantle plume. 3) Thought about what happened when the Indian subcontinent passed over the La Reunion plume = Deccan Traps volcanism. 4) Tried to find a good picture of the Deccan Traps. 5) Discovered that one of the few places to see Deccan Trap basalt layering is Lonar Crater. 6) Lonar Crater is said to be the only impact crater on volcanic basalt. 7) Found remote sensing and surface pictures of Lonar...

    Nature ^ | 9 June 2005
    This image from the Mars Express spacecraft shows a pocket of water ice nestling in a martian crater, bathed in the late martian summer sun. The shadow of the crater’s rim, which towers 300 metres over the surrounding plains, prevents the ice from vaporizing in the planet’s thin atmosphere. A dusting of frost survives inside the rim to the upper right, while the sun glimmers on its south-facing outer edge. The 35-kilometre-wide crater sits 70 north of the martian equator, in a low-lying region known as Vastitas Borealis. Previous orbiters have spotted ice deposits in craters, but the High Resolution...

    LOS ANGELES (AP) - NASA's Mars rovers don't seem to be wearing out so mission planners have begun to think more boldly, including a plan to let one climb up a steep "escape hatch" from a crater it has been exploring and set out on a trek across a plain. "The rovers have lasted longer than expected, but as long as we have them we're going to keep them busy," project manager Jim Erickson said Thursday in a conference call with reporters. Already on the second extension of their mission, the rovers Spirit and Opportunity have lasted so long that...
  • Report: Huge explosion in North Korean province [Crater seen by satellite.]

    A large explosion occurred in the northern part of North Korea, sending a huge column of smoke into the air on an important anniversary of the communist regime, a South Korean news agency reported Sunday. The South Korean government said it was trying to confirm the report of an explosion at 11 a.m. on Thursday in Yanggang province near the border with China. The Yonhap news agency carried reports from unidentified sources, with one in Washington saying the incident could be related to a natural disaster such as a forest fire. It also cited a diplomatic source in Seoul as...

    CAPE CHARLES, Va. - Geologists drilling half a mile below Virginia's Eastern Shore say they have uncovered more signs of a space rock's impact 35 million years ago. For more than two weeks, scientists drilled around the clock alongside a parking lot across the harbor from Cape Charles. They stopped at 2,700 feet. From the depths came jumbled, mixed bits of crystalline and melted rock that can be dated, as well as marine deposits, brine and other evidence of an ancient comet or asteroid that slammed into once-shallow waters near the Delmarva Peninsula. Cape Charles is considered Ground Zero for...

    WASHINGTON - Scientists have discovered signs of a large impact crater buried off the coast of Australia that may be linked to the biggest extinction event in Earth's history, the "Great Dying" 250 million years ago. Many scientists have long blamed a massive meteor near Mexico's Yucatan Peninsula for wiping out the dinosaurs 65 million years ago. What caused the far earlier and larger Permian-Triassic extinction — when about 90 percent of all species disappeared — is subject to sharper debate. The leading theory is that the extinction actually stretched over thousands of years, triggered by volcanic eruptions. A massive...

    PASADENA, Calif. (AP) - NASA scientists said Thursday they may send the Opportunity rover on a one-way trip to the depths of a crater on Mars so the robot can finish out its days studying stacks of layered rock that may have formed long ago at the bottom of a salty extraterrestrial ocean. The multiple layers of bedrock that line much of the inner slope of Endurance crater stand in cliffs 16 to 33 feet tall in places. They are seen in a sweeping color panorama that NASA released Thursday at Jet Propulsion Laboratory. "It's the most spectacular view we've...
