Archaeologists measured the magnetic fields found in clay bricks to determine the construction date of Babylon's Ishtar Gate.Babylon's bright-blue Ishtar Gate was thought to have been built to celebrate the conquest of Jerusalem — but a new analysis finds that it may have been erected years later.The iconic glazed-brick edifice, which King Nebuchadnezzar II ordered to be built and decorated with wild bulls and mušhuššu-dragons while ruling the Babylonian empire from 605 to 562 B.C., was constructed in three phases and served as the entrance to the ancient city of Babylon, located in southern Mesopotamia. However, the exact dates of...

Brick dates to the reign of Nebuchadnezzar II (ca. 604 to 562 BCE) based on the interpretation of the inscription. This object was looted from its original context before being acquired by the Slemani Museum and stored in that museum with agreement from the central government.

This archaeomagnetic approach provides a more precise method for dating ancient artifacts and understanding historical magnetic field fluctuations. Ancient bricks inscribed with the names...

A joint study by TAU and the Hebrew University, involving 20 researchers from different countries and disciplines, has accurately dated 21 destruction layers at 17 archaeological sites in Israel by reconstructing the direction and/or intensity of the earth's magnetic field recorded in burnt remnants. The new data verify the Biblical accounts of the Egyptian, Aramean, Assyrian, and Babylonian military campaigns against the Kingdoms of Israel and Judah.

The crack in the magnet field was created by a rare phenomenon called a co-rotating interaction region (CIR) from the Sun. CIRs are large-scale plasma structures generated in the low and mid-latitude regions of the heliosphere – the region surrounding the Sun that includes the solar magnetic field and the solar winds – when fast and slow-moving streams of solar wind interact. Like coronal mass ejections (CMEs), CIRs get flung out from the Sun towards Earth and can contain shockwaves and compressed magnetic fields that cause stormy space weather, which usually presents itself to us as pretty aurorae. This one...

The faster growth under Indonesia's Banda Sea hasn't left the core lopsided. Gravity evenly distributes the new growth—iron crystals that form as the molten iron cools—to maintain a spherical inner core that grows in radius by an average of 1 millimeter per year. But the enhanced growth on one side suggests that something in Earth's outer core or mantle under Indonesia is removing heat from the inner core at a faster rate than on the opposite side, under Brazil. Quicker cooling on one side would accelerate iron crystallization and inner core growth on that side. This has implications for Earth's...

The scans for MH370 revealed that the ocean crust rises and falls in waves that start at the Southeast Indian Ridge and continue outward. The ridge spreads about 35 millimeters in opposite directions every year, and the wave crests, where crust grew faster, are more than 100 kilometers long and repeat every 10-14 kilometers. The researchers estimated when each wave formed by comparing the bathymetry maps to independent measurements and models of the crust's magnetic field. ...Crustal rocks record the polarity of Earth's magnetic field as they form, allowing scientists to trace the age of different sections of ocean crust....

<p>Ship logs and pottery show how the geomagnetic field has changed.</p> <p>Old ship records of magnetic north have helped to unravel a record of our planet's field.</p> <p>While sailors plied the Seven Seas in the seventeenth and eighteenth centuries, little did they know that their ships' logs would one day help scientists to reconstruct the history of the Earth's magnetic field.</p>

Earlier this year, US National Oceanic and Atmospheric Administration and the British Geological Survey (BGS) were forced to update the World Magnetic Model a year ahead of schedule due to the speed with which the magnetic north pole is shifting out of the Canadian Arctic and toward Russia’s Siberia. The BGS and the US National Centers for Environmental Information has released a new update to the World Magnetic Model this week, confirming that the magnetic north pole, whose coordinates are crucial for the navigation systems used by governments, militaries and a slew of civilian applications, is continuing its push toward...

A joint study by Tel-Aviv University and the Hebrew University, involving 20 researchers from different countries and disciplines, has accurately dated 21 destruction layers at 17 archaeological sites in Israel by reconstructing the direction and/or intensity of the Earth's magnetic field recorded in burnt remnants. The new data verify the Biblical accounts of the Egyptian, Aramean, Assyrian, and Babylonian military campaigns against the Kingdoms of Israel and Judah. Findings indicate, for example, that the army of Hazael, King of Aram-Damascus, was responsible for the destruction of several cities: Tel Rehov, Tel Zayit, and Horvat Tevet, in addition to Gath of...

Jupiter's Spots Disappear Amid Major Climate Change By Robert Roy Britt Senior Science Writer posted: 01:00 pm ET 21 April 2004 Jupiter is undergoing major climate change and could lose many of its large spots over the next seven years, only to make way for the creation of fresh spots in a decades-long cycle, according to a new explanation of old mysteries. While the analysis remains to be proven, it is seen by other researchers as interesting and, importantly, testable even with large backyard telescopes. Philip Marcus, a professor at the University of California, Berkeley who came up with the...

Earth's magnetic field - the force that protects us from deadly radiation bursts from outer space - is weakening dramatically. Scientists have discovered that its strength has dropped precipitously over the past two centuries and could disappear over the next 1,000 years. The effects could be catastrophic. Powerful radiation bursts, which normally never touch the atmosphere, would heat up its upper layers, triggering climatic disruption. Navigation and communication satellites, Earth's eyes and ears, would be destroyed and migrating animals left unable to navigate. 'Earth's magnetic field has disappeared many times before - as a prelude to our magnetic poles flipping...

Researchers are preparing to test the highly controversial theory of a San Diego scientist, J. Marvin Herndon, who thinks a huge, natural nuclear reactor or "georeactor" -- a vast deposit of uranium several miles wide -- exists at Earth's core, thousands of miles beneath our feet... [I]t might help to explain otherwise puzzling phenomena of planetary science, such as fluctuations in the intensity of Earth's magnetic field... If Herndon's theoretical nuclear reactor really exists, then it should be gushing out antineutrinos that would fly through the roughly 4,000 miles of solid rock and emerge at the Earth's surface.

Last Updated: Thursday, 27 March, 2003, 12:02 GMT Is the Earth preparing to flip? By Dr David Whitehouse BBC News Online science editor Finding the shifting magnetic pole It is not just the plot for a far-fetched science-fiction disaster movie. Something unexplained really is happening to the Earth's magnetic field. In recent years, the field has been behaving in ways not previously seen in the admittedly short time it has been monitored. Some researchers think it may presage a geomagnetic reversal when the north and south magnetic poles flip. Such speculation takes place as the science-fiction movie The Core goes...

Ancient history as taught today is a disaster area. The chronology of the first and second millennium BCE is badly wrong.
