Earth’s magnetic past wasn’t as simple as today.
Scientists finally crack down a puzzle that has eluded the community for years. It seems sea level rise does indeed slow down Earth’s spin.
Even inside the Great Pyramid of Giza, outside of Cairo, researchers have found something interesting.
Researchers at MIT have developed a device that can track human silhouettes behind walls using Wi-Fi.
Just as the Moon is causing waters on Earth to go up and down (tides), so too does the Earth affect the Moon. Recently, researchers have found that our planet’s gravitational pull is having a deep effect on our satellite, opening new cracks and faults on its surface.
We tend to think of the Stonehenge as a lone giant, huge blocks of rock towering over the quiet British landscape. But as a new study has revealed, Stonehenge was likely a diverse and vibrant place, a complex of different religious and cultural settings. Painting Stonehenge in New Light Using geophysical techniques (mostly Ground Penetrating Radar – GPR –
A major Viking hall measuring over 50 metres in length has been identified near Vadstena in Sweden. Archaeologists from Stockholm University and Umeå University used non-invasive geophysical techniques to identify the hall, and they have a very good idea how it looked like, even without actually digging it. The Viking Age is the period from 793 AD to 1066 AD in European history,
It’s one of England’s better kept secrets – Old Sarum is a hidden gem among gems, one of the most spectacular ancient sites in Europe and in the world. Old Sarum is the site of the earliest settlement of Salisbury in England. The site contains evidence of human habitation as early as 3000 BC, but only now have archaeologists uncovered the
Scientists have discovered an almost rectangular feature consisting of ancient magma. The features are similar to rifts here on Earth, a linear zone where the Earth’s crust and lithosphere are being pulled apart. However, since the Moon doesn’t have any plate tectonics to cause rifts, the origin of this magma is still questionable. Magma on the Moon Several kilometers below the
Stonehenge is one of Britain’s greatest national treasure, but while magic, myth and mystery surrounding the monumental site has been time and time again dispelled by science, there is still much to learn. One major debate regarding Stonehenge is whether or not the site once formed a complete circle. Now, a short hosepipe and a scientist’s keen eye might settle
For the first time, geophysicist in New Zealand will place seismic sensors deep into a geological fault to record the build-up and occurrence of massive earthquakes, potentially giving crucial information about one of the biggest faults in the world. It’s hard to say anything after such an insightful and well explained video. The Alpine Fault runs for about 600 kilometres
The former popular landscape was an expanse of warped shapes, out of which some were as tall as a Manhattan skyscraper, and it was discovered by an ice-penetration radar loaded aboard NASA survey flights. According to the scientists who made the discovery, this could deepen the level of understanding concerning the way in which the ice sheets of Greenland and
A researchers from the University of Southampton has developed a a wireless network of sensors that is set to revolutionize soil-based salinity measuring. Testing the salinity levels in soils is a big deal – any salty water infiltrations can have massive effects on agriculture and sometimes, even on soil stability. At the moment, you can analyze soil salinity either indirectly,
A laudable, ambitious initiative is nearing fruition: the US$90-million Transportable Array, a moveable grid of seismometers that blankets America. Since 2004, the set of 400 seismometers, loaded on trucks, have gradually marched, from the Pacific coast across the Rocky Mountains and the Great Plains and is finally reaching the eastern coastline. Whenever they arrive at the specified location, scientists dig
Scientists at Scripps Institution of Oceanography at UC San Diego have found a layer of liquefied molten rock in Earth’s mantle that may be acting as a lubricant for the sliding motions of the planet’s tectonic plates. This discovery has very far reaching implications, which can solve some of the long standing geological puzzles, as well as lead to a
Evidence of drowned remnants of an ancient microcontinent have been found in sand grains from the beaches of a small Indian Ocean island, according to a new research. Zircons and volcanoes This evidence was found in Mauritius, a volcanic island 900 kilometres east of Madagascar which serves as an exotic destination for many tourists. Basaltic rocks from the island have
The past few years have been marked by numerous seismic events, some of dramatic magnitude; aside from the huge 9.1 temblor in Japan, the world was also shocked by the pair of massive earthquakes that rocked the Indian Ocean on 11 April 2012. However, as geophysicists warn, this may only be the beginning – the birth of a new plate
Planetary scientist Kelsi Singer initially studied satellite photographs of Saturn’s icy moon Iapetus‘ surface looking for stress fractures in the moon’s ice, what she found in process however was far more interesting. Huge landslides, stretching across tens of miles across the moon’s surface were observed, not in one, but multiple locations, hinting this is a common phenomenon on the ice covered satellite.
Scientists at MIT, Brown University, and NASA’s Goddard Space Flight Center may have come across an incredible discovery, after data from the Lunar Reconnaissance Orbiter (LRO), a spacecraft which orbits the Moon from pole to pole, suggests water ice might be present inside a massive crater, called the Shackleton crater. The researchers used the spacecraft’s laser altimeter to illuminate the crater’s interior with infrared laser light, measuring how
The Yellowstone super volcano, which basically outlines the whole Yellowstone National Park, is part of one of the most active volcanic regions in the world. A recent research conducted by a joint team of international scientists from Washington State University and the Scottish Universities Environmental Research Centre is set to cast doubts on the frequency of eruptions and, most importantly, super eruptions from the Yellowstone area, which
